New website for The Theropod Database plus new nomina nuda

I had to move hosts, so the new website for The Theropod Database is
https://theropoddatabase.github.io/ .  We're working out some encoding issues for special characters, but in the meantime here are some nomina nuda that have not been reported before.

I'm sure Dalman's new tyrannosaur names have been making the rounds based on his new curriculum vitae at https://www.montana.edu/earthsciences/graduate-program/students/cv/Sebastian_Dalman.html .  Here's some informed guesswork as to what they are...

"Bistityrannus" Dalman, Jasinski, Lucas, Malinzak, Loewen, Fiorillo and Currie, in progress/review in Dalman, online 2024
?= "Alamotyrannus" Dalman and Lucas, in press in Dalman, 2013 in part
"B. anax" Dalman, Jasinski, Lucas, Malinzak, Loewen, Fiorillo and Currie, in progress/review in Dalman, online 2024
?= "Alamotyrannus brinkmani" Dalman and Lucas, in press in Dalman, 2013 in part
Etymologies- Bisti is Navajo for "large area of shale hills" after the Bisti/De-Na-Zin Wilderness Area where the specimen was probably found + Latin tyrannus "ruler", common suffix for tyrannosauroids.  Greek anax "tribal chief or leader".
Alamo after the Ojo Alamo Formation where the material is from, in turn named for the Ojo Alamo trading post + Latin tyrannus "ruler", common suffix for tyrannosauroids. brinkmani probably from vertebrate paleontologist Donald B. Brinkman.
Late Campanian, Late Cretaceous
De-na-zin Member of Kirtland Formation?, San Juan Basin, New Mexico, US
Material- ?(ACM 7975; intended syntype of "Alamotyrannus brinkmani") anterior right dentary (~142 mm deep) (Dalman, 2013)
Campanian-Maastrichtian, Late Cretaceous
San Juan Basin, New Mexico, US
?(PMU.R35; = PMU.R85 of Carr and Williamson, 2000 Appendix 1; = PMU.R1235 of Carr and Williamson, 2000 Fig. 9G-H and Appendix 1; intended syntype of "Alamotyrannus brinkmani"?) anterior right dentary (Sullivan and Williamson, 1997)
Comments- ACM 7975 was discovered in July or August 1924, and figured and briefly described by Dalman and Lucas (2016) as "Tyrannosauridae indeterminate" despite the authors listing two characters purportedly differentiating it from other tyrannosaurids.  Namely, "the possession of two foramina intermandibularis oralis" and "the morphology of the anterior step of the lingual bar" which "is anterodorsally inclined and has a relatively short posterior surface (towards the mouth), whereas in other tyrannosaurids (e.g., Daspletosaurus, Tarbosaurus, and Tyrannosaurus) the posterior surface of the step is well-developed and nearly the same length as the dorsal surface."
Dalman (2013) stated "the many isolated but diagnostic tyrannosaurid skeletal fossil elements from the Naashoibito Member of the Ojo Alamo Formation (early Maastrichtian) of northwestern New Mexico (Sullivan et al. 2005; Jasinski et al. 2011; Dalman and Lucas, in press) provide evidence for the occurrence of a new taxon of a large tyrannosaurid" with the in press paper's bibliographic entry naming it "Alamotyrannus brinkmani." Stuchlik (pers. comm. to Dalman, 7-2018) informs me the intended holotype was two dentaries, presumedly including ACM 7975 that was mentioned in Dalman (2013) as "the new Ojo Alamo tyrannosaurid taxon ACM 7975." Dalman (pers. comm. to Demirjian, 2015) stated the paper is postponed as more complete remains were discovered, and that the taxon would receive a different name.  A probable explanation is that Dalman and Lucas (2016) briefly described and figured ACM 7975 as a diagnostic tyrannosaurid under study by Dalman but noted that the previous referral to the Ojo Alamo Formation was due to its discoverer Loomis using an old, broader definition for the formation.  Geographical and preservational data indicated instead that ACM 7975 was probably from the De-na-zin Member of the Kirtland Formation, so mixing it with the diagnostic Ojo Alamo elements noted by Dalman (2013) would make his "Alamotyrannus" concept a chimaera.  Thus Dalman would want to describe the diagnostic Kirtland dentary and the diagnostic Ojo Alamo elements as different taxa, which seems to be the plan based on his 2024 online curriculum vitae. 
This lists "Dalman, S.G., Jasinski, S.E., Lucas, S.G., Malinzak, D.E., Loewen, M.A., Fiorillo, A.R., Currie, P.J. 2024. Bistityrannus anax, a new tyrannosaurid from the Kirtland Formation (Upper Cretaceous) of northwestern New Mexico. Cretaceous Research (in review/in progress)" under Published Research despite being unpublished as of 9-21-2024.  The genus and species are obviously invalid pending this publication as his online curriculum vitae is not "issued for the purpose of providing a public and permanent scientific record" (IZCN Article 8.1.1), "produced in an edition containing simultaneously obtainable copies by a method that assures 8.1.3.1. numerous identical and durable copies (see Article 8.4), or 8.1.3.2. widely accessible electronic copies with fixed content and layout" (Article 8.1.3), does not "state the date of publication in the work itself, and" is not "registered in the Official Register of Zoological Nomenclature (ZooBank) (see Article 78.2.4) and contain evidence in the work itself that such registration has occurred" (Articles 8.5.2 and 8.5.3), the taxa are not "accompanied by a description or definition that states in words characters that are purported to differentiate the taxon" (Article 13.1) or "explicitly indicated as intentionally new" (Article 16.1).
Another unpublished entry on that page with identical authorship is "Denazinosaurus sicarius, a new tyrannosaurid from the Kirtland Formation (De-na-zin Member) Upper Cretaceous of New Mexico, USA", giving us two proposed new Kirtland tyrannosaurids with nothing distinguishing them in their publication titles besides "Denazinosaurus" definitely being from the De-na-zin Member.  While either or neither of these could be intended for former "Alamotyrannus" dentary ACM 7975, it's here suggested the stratigraphic uncertainty behind that specimen's discovery makes De-Na-Zin unlikely to feature in the article title or genus name.  Thus ACM 7975 is probably "Bistityrannus", while "Denazinosaurus" would be a different specimen with a more definite locality.  Given most De-Na-Zin tyrannosaurid specimens are isolated teeth and postcrania (generally considered indeterminate in Tyrannosauridae), that ideally Dalman would want a specimen comparable to ACM 7975 to erect a new contemporaneous species distinct from it, and that he is describing other tyrannosaurids based on dentaries (see Fruitland Formation KU VP-96888), the obvious identity of "Denazinosaurus" would be classic dentary USNM V 8346 described by Gilmore in 1916 (see entry).  Whether this logic proves true awaits either publication. 
Interestingly, given Dalman originally intended to name "Alamotyrannus" based on two dentary syntypes including ACM 7975, it implies a second tyrannosaur dentary plausibly from the Ojo Alamo Formation.  While NMMNH P-7199 is an obvious possibility as the only dentary I know of confirmed from that formation, it's so poorly preserved that it's never even been figured.  I propose a more likely possibility is anterior dentary PMU.R35 whose locality can only be specified to San Juan County, and which seems to have the anterior step morphology described for ACM 7975- anterodorsally inclined with a short posterior surface (Sullivan and Williamson, 1997- Fig. 1D).  As its uncertain stratigraphic placement makes it plausibly from the De-Na-Zin Member, this may be an additional specimen of "Bistityrannus".  Discovered in 1921 or 1922, this was not published until Sullivan and Williamson's 1997 review of PMU specimens sent by Sternberg, where it is figured in lateral and medial views as "tyrannosaurid partial right dentary."

Late Campanian, Late Cretaceous
head of Hunter Wash / locality 60 of Bauer 1916, De-na-zin Member of Kirtland Formation, San Juan County, New Mexico, US
Material- ?(USNM V 8346) incomplete left dentary (tooth row length 354 mm) (Gilmore, 1916)
Comments- Discovered August 20, 1915, this was initially described by Gilmore (1916) as "Deinodon?" and figured in medial view.  He noted "In the number of tooth sockets this jaw agrees with Dynamosaurus imperosus Osborn,^a [now Tyrannosaurus rex] but in the general form of the dentary, particularly the contour of the anterior end, it approaches Albertosaurus⁴ (Dryptosaurus) most nearly, but as the dentary of Albertosaurus has sockets for 15 teeth the presence of 13 in this individual would appear to show its distinctness."  Gilmore further stated "It is quite possible that this dentary pertains to the genus Deinodon, but that can not be determined at this time because the dentary of that genus is unknown. The identification of this specimen must therefore await the discovery of additional material."  Gilmore (1920) repeated most of this verbatim, listing it as "DEINODON, species." this time.  In a later publication, Gilmore (1935) wrote "Comparison of this bone directly with a dentary of Gorgosaurus libratus Lambe from the Belly River of Canada now shows such close resemblances in size, shape, and other characteristics down to the smallest details as to leave little doubt of their being congeneric. Likewise, the number of alveoli (13) is in agreement with Lambe’s (1917) determination from a number of specimens that the dentary in this genus bears 13 or 14 teeth."  Lucas et al. (1987) felt the dentary "almost certainly pertain[s] to Albertosaurus" sensu Russell 1970, equating to modern Albertosaurinae.  Carr and Williamson (2000) figured the dentary in lateral, medial and dorsal views, and stated "Based on personal observation of this and other tyrannosaurid dentaries, this bone does not appear to be diagnostic at the specific or generic levels."  They noted "There are actually 14 dental alveoli" and concluded "Because the alveolus count of USNM 8346 overlaps with that of A. libratus and T. rex and in light of the fact that tooth count is variable in these species, we consider it best to consider this specimen as indeterminate Tyrannosauridae."  Indeed, 14 dentary alveoli are also present in some Albertosaurus sarcophagus (AMNH 5222, TMP 1986.064.0001), Daspletosaurus torosus (CMN 8506) and Tarbosaurus (IGM 107/7) specimens.

Material- ?(KU VP-96888) (~10 m) anterior left dentary (140 mm deep) (Dalman and Lucas, 2021)
Comments- Dalman and Lucas (2021) state "The specimen is being described by us in detail in another paper as belonging to a new genus and a new species" but contradictorally identify it as "Tyrannosauridae indet."  They also say "When compared to the dentaries of other tyrannosaurids such as Albertosaurus, Bistahieversor, Daspletosaurus, Gorgosaurus, Lythronax, Tarbosaurus, Teratophoneus and Tyrannosaurus, the body length of KUVP-96888 was close to 10 m."  This is listed as Tyrannosaurus sp. in the KU online catalog.
Coincidentally, Dalman's 2024 online curriculum vitae lists "Dalman, S.G., Jasinski, S.E., Loewen, M.A., Malinzak, D.E., Currie, P.J., Fiorillo, A.R., Lucas, S.G. 2024. Erinotonax sabathi, a new tyrannosaurid from the Fruitland Formation (Upper Cretaceous) of New Mexico, USA, insights into the evolution, diversity, and paleogeography of tyrannosaurids in North America.

Unless Dalman and Lucas are describing multiple new genera of tyrannosaurids from the Fruitland Formation, it seems likely "Erinotonax" is KU VP-96888.  Given its fragmentary and pathological condition, I'm skeptical of any future diagnosis.

"A. eversor" Dalman, Jasinski, Loewen, Lucas, Malinzak, Fiorillo and Currie, in progress/review in Dalman, online 2024
Etymology- Latin atrox "fierce" + ? Latin arius "agent of use", except the 'c' is unexplained and atrox is not a noun. Creisler (pers. comm 9-2024) suggests atrox + Latin cara "head" + Latin suffix -ius, but that should imply cranial remains which are not at all certain. Greek eversor "destroyer."

?(AMNH 5882) right pedal phalanx IV-2 (~143 mm) (Carr and Williamson, 2000)
Comments- Discovered May 7, 1998, NMMNH P-7199 is a partial dentary associated with tooth fragments and a partial vertebra that all remain unfigured.  Carr and Williamson (2000) refer it "to cf. T. rex on the basis of its large apical and midheight denticles, 7.5 denticles per 5 mm and 8.5 denticles per 5 mm, respectively" on the mesial carina and note the dentary and vertebra "are too weathered and incomplete to permit identification."  Jasinski et al. (2011) suggested however that "identification below the family level (Tyrannosauridae) based on denticle densities is tenuous" so retained it as Tyrannosauridae indet..  The NMMNH online catalog incorrectly lists this as being from the De-na-zin Member of the Kirtland Formation.
Jasinski et al. (2011) notes "The scapulocoracoid (SMP VP-2105, Fig. 7A-B) may be from an adult as it compares readily in size and morphology to the scapulocoracoids of Tyrannosaurus rex (FMNH PR2081; Brochu, 2003, fig. 80). While this indicates the presence of a large tyrannosaurid in the Naashoibito Member, the specimen cannot be confidently referred to Tyrannosaurus rex, but may represent Tyrannosaurus sp."
Femur SMP VP-1113 is first published as "SMP VP-? femur Naashoibito Mbr., Kirtland Fm. Tyrannosauridae indet" by Carr and Williamson (2000), then figured by Lucas and Sullivan (2000) as "Tyrannosauridae, incomplete femur."  Sullivan et al. (2005) identified it as "cf. Daspletosaurus sp., based on comparison with USNM 10754, a right femur of either Gorgosaurus or Daspletosaurus sp. (labelled as Albertosaurus sp.) ... from the Dinosaur Park Formation" because "the size and morphology of SMP VP-1113 closely resembles that of USNM 10754", but the only stated character is gracility compared to Tyrannosaurus, which is true for almost all other tyrannosaurids.
Jasinski et al. (2011) figure a metatarsal I (incorrectly called "the 1st phalanx of the 1st metatarsal" on page 226), which along with femur SMP VP-1113 they state is "from a large tyrannosaurid that seems more gracile than an adult Tyrannosaurus rex, although they may represent a juvenile or sub-adult."
Lehman (1981) wrote "single, complete, right fourth metatarsal (on loan from the collection of Ronald P. Ratkevich of Alamogordo, New Mexico) is tentatively referred here to Albertosaurus sp." using the broad concept of the genus popular at the time where it included Gorgosaurus.  It is figured in anterior, medial and five sectional views.
Carr and Williamson (2000) reported "a large pedal phalanx (AMNH 5882; Fig. 4A-F) was collected from the Naashoibito Member of the Kirtland Formation. The collector and date of collection of this specimen are unknown" and figured it in multiple views as Tyrannosauridae indet..  Oddly, the AMNH online catalog lists this as being collected by Brown from the Hell Creek Formation of Snow Creek, Montana, but does correctly list it as a "2nd phalanx" of Theropoda.  Williamson and Carr (2005) referred the phalanx to cf. Tyrannosaurus rex in an abstract.
"Alamotyrannus" into "Atroxicarius"- Dalman (2013) stated "the many isolated but diagnostic tyrannosaurid skeletal fossil elements from the Naashoibito Member of the Ojo Alamo Formation (early Maastrichtian) of northwestern New Mexico (Sullivan et al. 2005; Jasinski et al. 2011; Dalman and Lucas, in press) provide evidence for the occurrence of a new taxon of a large tyrannosaurid" with the in press paper's bibliographic entry naming it "Alamotyrannus brinkmani." Stuchlik (pers. comm. to Dalman, 7-2018) informs me the intended holotype was two dentaries, presumedly including ACM 7975 that was mentioned in Dalman (2013) as "the new Ojo Alamo tyrannosaurid taxon ACM 7975." Dalman (pers. comm. to Demirjian, 2015) stated the paper is postponed as more complete remains were discovered, and that the taxon would receive a different name.  A probable explanation is that Dalman and Lucas (2016) briefly described and figured ACM 7975 as a diagnostic tyrannosaurid under study by Dalman but noted that the previous referral to the Ojo Alamo Formation was due to its discoverer Loomis using an old, broader definition for the formation.  Geographical and preservational data indicated instead that ACM 7975 was probably from the De-na-zin Member of the Kirtland Formation, so mixing it with the diagnostic Ojo Alamo elements noted by Dalman (2013) would make his "Alamotyrannus" concept a chimaera.  Thus Dalman would want to describe the diagnostic Kirtland dentary and the diagnostic Ojo Alamo elements as different taxa, which seems to be the plan based on his 2024 online curriculum vitae. 
This lists "Dalman, S.G., Jasinski, S.E., Loewen, M.A., Lucas, S.G., Malinzak, D.E., Fiorillo, A.R., and Currie, P.J. 2024. Atroxicarius eversor, a new tyrannosaurid from the Ojo Alamo Formation (Upper Cretaceous) of New Mexico, USA, new insights into the evolution of bistahiversorin tyrannosaurids in North America. Anatomical Records (in review/in progress)" under Published Research despite being unpublished as of 9-21-2024 and presumedly referring to The Anatomical Record.  This would then seem to be the new name of the Ojo Alamo tyrannosaurid, which the title suggests is related to Bistahieversor in a new tribe "Bistahieversorini", although note Dalman misspelled it without the first 'e'. The tribe, genus and species are obviously invalid pending this publication as his online curriculum vitae is not "issued for the purpose of providing a public and permanent scientific record" (IZCN Article 8.1.1), "produced in an edition containing simultaneously obtainable copies by a method that assures 8.1.3.1. numerous identical and durable copies (see Article 8.4), or 8.1.3.2. widely accessible electronic copies with fixed content and layout" (Article 8.1.3), does not "state the date of publication in the work itself, and" is not "registered in the Official Register of Zoological Nomenclature (ZooBank) (see Article 78.2.4) and contain evidence in the work itself that such registration has occurred" (Articles 8.5.2 and 8.5.3), the taxa are not "accompanied by a description or definition that states in words characters that are purported to differentiate the taxon" (Article 13.1) or "explicitly indicated as intentionally new" (Article 16.1) and even a correctly spelled "bistahieversorine" is not in Latinized form (article 11.7.2) nor is it "accompanied by citation of the name of the type genus" (Article 16.2).  Based on another Dalman et al. (in review/progress) citation in Dalman's curriculum vitae, the De-na-zin tyrannosaurid will be named "Denazinosaurus sicarius" and preseumedly includes dentary ACM 7975 as the intended holotype.
It's unknown which specimens will be types of "Atroxicarius", but as Dalman (2013) cited skeletal (not dental, which are generally undiagnostic) elements described by Sullivan et al. (2005) and Jasinski et al.

But we also have a few other nomina nuda based on early versions of papers.

Fujianvenator Xu, Wang, Chen, Dong, Lin, Xu, Tang, You, Zhou, Wang, He, Li, Zhang and Zhou, 2023
F. prodigiosus Xu, Wang, Chen, Dong, Lin, Xu, Tang, You, Zhou, Wang, He, Li, Zhang and Zhou, 2023
= Fujianvenator "rapidus" Xu, Wang, Chen, Dong, Lin, Xu, Tang, You, Zhou, Wang, He, Li, Zhang and Zhou, 2023
Etymology- The apparent early species name "rapidus" is no doubt from Latin rapidus "quick", as the authors state "Fujianvenator was well adapted for terrestrial locomotion and is likely to have been capable of running at a high speed."
Comments- Xu et al.'s (2023) reporting summary states "The holotype of Fujianvenator rapidus (IVPP V31985) was discovered in Daxi Basin near Yangyuan Village, Zhenghe Country, Nanping City, Fujian Province, Southeast China" three times, making this a likely early name for F. prodigiosus.

H. matsubaraetoheorum Kubota, Kobayashi and Ikeda, 2024
= Hypnovenator "sasayamaensis" Kubota, Kobayashi and Ikeda, 2024 online
Etymology- "The specific name, "sasayama", refers to previous name of a city placed in the eastern region of Hyogo Prefecture, from where the holotype specimen was collected. It also refers to an amateur group "Association to Study the Sasayama Group", to which the two discovers belong."
Comments- The species name "sasayamaensis" was used in the preprint of the article.

Daspletosaurus wilsoni Warshaw and Fowler, 2022
= Daspletosaurus "diadematus" Warshaw, Wilson and Fowler, 2022 online
Etymology- "Diadematus, Latin for “crowned,” in reference to the novel postorbital horn morphology unique to this species, and its diagnosis as a tyrant dinosaur."
Comments- The initial manuscript called this D. "diadematus", which was replaced by wilsoni after its discoverer John Wilson was removed from the authorship.

Fonseca et al (2024) perform a Lori-style analysis of basal Ornithischia

This post is a shout-out to Fonseca et al. (2024), whose abstract states-

"Resolving the evolutionary relationships of early diverging (‘basal’) ornithischian dinosaurs is a challenging topic in palaeontology, with multiple competing hypotheses on the phylogenetic relationships of heterodontosaurids, ‘hypsilophodontids’, and other early-diverging forms. These hypotheses cannot be directly compared because they are derived from differently constructed datasets (i.e. distinct samples of taxa and characters). This study aims to address these issues by revising and combining the distinct datasets into a single analysis in order to create the most comprehensive dataset for the investigation of the phylogenetic relationships of early-diverging ornithischians."

This is the ideal for a phylogenetic analysis and exactly what I attempted for Lori, providing some useful data.  They write "constrained analysis forcing a close affinity between Heterodontosauridae and Marginocephalia require at least 26 extra steps, while joining them and Pachycephalosauria require at a minimum 44 steps", so those are implausible.  The weird little bipedal armored Jakapil comes out sister to Eurypoda, and "enforcing it as a marginocephalian requires 16 additional steps" so is unlikely.  Making it parankylosaurian requires only 4 steps though, so is quite likely and matches geographically.  For as much crap as I gave Norman's phylogenetic nomenclature, his Hypsilophodontia including Tenontosaurus (and other rhabdodontomorphs) only takes 6 more steps, so is less likely but not bad.  While Fonseca et al.'s main results are interesting, I found the supplementary information where they commented on all the taxa they excluded equally informative.

Teeth of Ferganocephale adenticulatum- A-B paratype ZIN PH 31/42; C-F holotype ZIN PH 34/32; G-J paratype ZIN PH 36/42; K-N paratype ZIN PH 33/42. Apical- A, C, G, N; Mesial or distal- B, E, I, L; Labial or lingual- D, F, H, J, K, M. After Averianov et al., 2005.

"Ferganocephale adenticulatum Averianov et al. (2005) displays no ankylothecodonty (ch388:0), low crowns (ch411:0), round crown apices (ch413:1), no apicobasal ridges (ch421:0), an asymmetric labiolingual expansion (ch422:1), a cingulum (ch423:1), and no denticles. While these features show the most similarity to Chaoyangsauridae, the lack of denticles and strength of the cingulum are very different from the clade, so a classification as intermediate Saphornithischia is most likely. The position of Ferganocephale adenticulatum requires further work done to assess the dental morphologies within Pan-Aves as a whole, especially due to its un-archosauriform lack of denticulation (see Ezcurra, 2016)."

Holotype right maxilla of Lusitanosaurus liassicus in lateral view (University of Lisbon coll.; destroyed). After Lapparent and Zbyszewski, 1957.

"Lusitanosaurus liassicus Lapparent and Zbyszewski (1957) displays ankylothecodont teeth (ch388:1), low crowns (ch411:0), no recurvature (ch414:2), no apicobasal ridges (ch421:0), and no cingulum (ch423:0). The type specimen was lost in a fire (Mateus et al., 2022), so the only information available about the taxon is from the original description and plate of Lapparent and Zbyszewski (1957). The crowns are tricuspid, which is shared with members of Pterosauria (Dalla Vecchia, 2013), Squamata (Conrad, 2008), Tanystropheidae (Renesto & Dalla Vecchia, 2000; Spiekman et al., 2020), and basal Cynodontia (Hahn et al., 1984) but not Ornithischia. The lack of a cingulum also suggests Lusitanosaurus liassicus is not an ornithischian, as that was the only feature identified by Irmis et al. (2007) to distinguish early ornithischian teeth from similar but non-ornithischian phyllodont teeth. While it has been previously excluded from studies as a dubious basal thyreophoran (Antunes & Mateus, 2003; Norman et al., 2004a; Norman, 2020c), the distribution of anatomy instead suggests that Lusitanosaurus liassicus cannot be considered an ornithischian and should instead be considered Archosauromorpha indeterminate on the basis of ankylothecodont tooth implantation."

Teeth of Taveirosaurus costai- A paratype TV 16; B paratype TV 11; C paratype 14; D-E, J-K holotype TV 10; F paratype TV 8; G paratype TV 7; H paratype TV 13; I paratype TV 9. Lingual- A-D, F-J; Labial- E, K. After Antunes and Sigogneau-Russell, 1991.

"Taveirosaurus costai Antunes and Sigogneau-Russell (1991) displays cheek tooth crowns without mesial and distal ‘kinks’ (ch412:0), low crown height (ch411:0), coarse denticles (ch416:2), and no cingulum (ch423:0), which would support a position just within or outside Ornithischia. However, the morphology of the crowns is very divergent from ornithischians, and the only features linking the taxon with Ornithischia are also found in non-ornithischian archosauromorphs (Irmis et al., 2007), mammaliforms (Luo et al., 2002) and even hybodontiformes (Stumpf et al., 2022). Taveirosaurus costai is considered to belong to Eutriconodonta here on the basis of linear molar cusps and a distinct, straight cingulum (Luo et al., 2002) as well as its Late Cretaceous age, until further work is done to establish possible shared dental morphology with Ornithischia."

Holotype tooth of Trimucrodon cuneatus (Lehrstuhl für Paläontologie coll.). Lingual- a; Labial- b. After Thulborn, 1973.

"Trimucrodon cuneatus Thulborn (1973) displays sporadic wear facets (ch407:0), low crowns (ch411:0), kinked mesial and distal crown edges (ch412:1), triangular crown apices (ch413:0), no recurvature (ch414:2), mesiodistal expansion above the root (ch415:1), no apicobasal ridges (ch421:0), symmetric labiolingual expansion (ch422:0), and no cingulum (ch423:0). These features show significant conflict, especially the lack of a cingulum and asymmetrical labiolingual swelling which are exclusive synapomorphies of Parapredentata except for clades that are excluded for other characters (eg. lack of apicobasal ridges). Until further work is done to assess the dental morphologies within Pan-Aves as a whole, Trimucrodon cuneatus should be retained as a possibly valid taxon that cannot be classified beyond Ornithischia outside Parapredentata."

Several taxa like Alocodon, Phyllodon and Xiaosaurus are considered valid despite generally being ignored due to being fragmentary.  They even include a large supplement illustrating their characters, and justifying which characters were not included.  And you can tell they went up to the submission limit by commenting on recent taxa like Vectidromeus and Chakisaurus.

Things I wish Fonseca et al. would have done are list the possible positions of the taxa excluded WISELY a posteriori- "Daemonosaurus chauliodus; Diodorus scytobrachion; Gamatavus antiquus; Sacisaurus agudoensis; Mymoorapelta maysi; Nevadadromeus schmitti; Hualianceratops wucaiwaneisis; Beg tse; Ceratops montanus; the ‘Vegagete ornithopod’; Weewarrasaurus pobeni; Atlascopcosaurus loadsi; Galleonosaurus dorisae; Leaellynasaura amicagraphica; Qantassaurus intrepidus; Trinisaura santamartaensis; Isasicursor santacrucensis; Sektensaurus sanjuanboscoi; Callovosaurus leedsi; and Draconyx loureiroi", and scorings for the excluded taxa like Vectidromeus and "Hypsilophodon" wielandi.  Also more constraint analyses for things like the position of Lesothosaurus and Albalophosaurus (here the earliest pachycephalosaur).

Now we need someone to do this for the 30+ incertae sedis sauropodomorph taxa everyone's ignored for over three decades since they were kicked out of Plateosaurus/Massospondylus/Euskelosaurus using Yates' matrix or something better.

Correct citations for Sinosauropteryx and Protarchaeopteryx

A quick one today based on the fact I just found out the entirety of Chinese Geology is free online.  Ji and Ji used it for their early Yixian feathered theropod descriptions in the 90s.  Back then getting Chinese papers in the West was not as easy as today, and as Sinosauropteryx and Protarchaeopteryx both got redescribed in Nature in 1998 and had their original descriptions translated by Downs in 2001 and uploaded to The Polyglot Paleontologist, I think most researchers never bothered to hunt down the Chinese originals.  But now that they're easily available, I've noticed everyone's been copying the incorrect citations in the Nature or Downs' papers, so this post is here to sort that out.



Sinosauropteryx

https://www.cgsjournals.com/article/id/zgdz_DIZI199610011

Note these mid-90s papers don't actually have English titles.  The first published was the original description of Sinosauropteryx, given by Chen et al. (1998) as-

Ji, Q. & Ji, S. A. On discovery of the earliest bird fossil in China and the origin of birds. Chinese Geol. 233, 30–33 (1996).

And by Downs' 2001 translation as-

Qiang Ji and Shu’an Ji. On the Discovery of the earliest fossil bird in China (Sinosauropteryx gen. nov.) and the origin of birds. Chinese Geology. Volume 233. 1996. pp. 30-33.

But the actual citation is-

Ji and Ji, 1996. 中国最早鸟类化石的发现及鸟类的起源. Chinese Geology. 23(10) (total issue 233), 30-32.

Chen et al.'s is closer, as Google Translate translates the Chinese title as "The discovery of the earliest bird fossils in China and the origin of birds", and it certainly doesn't say "Sinosauropteryx gen. nov." which would be "中华龙鸟属新属".  I'm curious to know if there was a page 33 that the Chinese Geology scanners missed, perhaps containing a figure like the last pages of the next two articles (since there are no figures in the paper otherwise).

Skull of NGMC 2124 (photo by Mortimer at the TMP in 1999).

https://www.cgsjournals.com/article/id/zgdz_DIZI199707010

A second paper describing supposed Sinosauropteryx specimen NGMC 2124 was published the following year, and sadly remains the only paper describing this unique taxon (recovered a couple weeks ago as a juvenile tyrannosauroid in Cau's ontomatrix).  Currie and Chen (2001) give the reference as-

Ji, Q., and Ji, S.-A. 1997b. Advances in the study of the avian Sinosauropteryx prima. Chinese Geology, 242: 30–32 (in Chinese).

And there's an HTML translation that was online (as of 2010) that gives it as-

Ji Qiang & Ji Shuan, Advances in Sinosauropteryx Research, Chinese Geology, 1997, 7, p. 30-32 and cover page 3.

But the actual citation is-

Ji and Ji, 1997. 中华龙岛(Sinosauropteryx) 化石研究新进展. Chinese Geology. 24(7) (total issue 242), 30-32, 49.

Google Translate translates the Chinese title to "New progress in the study of Sinosauropteryx fossils" which seems more accurate than Currie and Chen's as the species name is certainly never mentioned.



Protarchaeopteryx

https://www.cgsjournals.com/article/id/zgdz_DIZI199703012

Ji et al. (1998) give the reference as-

Ji, Q. & Ji, S. A. Protarchaeopterygid bird (Protarchaeopteryx gen. nov.)—fossil remains of archaeopterygids from China. Chinese Geol. 238, 38–41 (1997).

Downs' 2001 translation gives us-

Qiang Ji and Shu’an Ji. A Chinese archaeopterygian, Protarchaeopteryx gen. nov.. Geological Science and Technology (Di Zhi Ke Ji). Volume 238. 1997. pp. 38-41.

But the actual citation is-

Ji and Ji, 1997. 恩错祖鸟(Protarchaeopteryx gen. nov.) - 中国的始祖鸟类亿右. Chinese Geology. 24(3) (total issue 238), 38-41, 49.

The first four characters (恩错祖鸟) translate to Protarchaeopteryx, so "protarchaeopterygid" is an invention of Ji et al., made more obvious by the fact it was classified as an archaeopterygid in the paper.  The implied family 'Protarchaeopterygidae' has never been published so remains unofficial.  Google Translate gives the translation "Protarchaeopteryx gen. nov. - Archaeopteryx of China."

Center of Protarchaeoptery holotype.

Lingyuanornis

https://www.cgsjournals.com/article/id/zgdz_DIZI199903021

I think the only other dinosaur described in Chinese Geology is Lingyuanornis, an objective junior synonym of Liaoxiornis that may have been first cited in Western literature by Chiappe and Walker (2002) as-

Ji Q. and Ji S.-A. 1999. A new genus of the Mesozoic birds from Lingyuan, Liaoning, China. Chinese Geology 262:45–48.

As English titles were a thing by now, the actual citation is pretty similar-

Ji and Ji, 1999. A new genus of the Mesozoic birds from Lingyuan, Liaoning, China. Chinese Geology. 26(3) (total issue 262), 45-49.

The volume issue

One obvious difference in citations besides the titles and page numbers are the volume numbers, with most prior citations using what appears to be a single large number representing the issue perhaps all the way from 1954 when the journal started.  However, the format the Chinese Geology website has is one with volumes corresponding to year (from 1958 forward), then issues of a variable number within that year.  The HTML Ji and Ji 1997 'Sinosauropteryx' translation does give the issue number (7) correctly, but none of them cite the volume corresponding to the official website.  Notably, the latter includes photos of all the issue covers showing the issue format was there from the beginning.  Also interesting is that while the 1996-1998 papers themselves have no indication of a volume or issue, Lingyuanornis' does include both "总第262 期 中 自 地 质" and "1999 年第3 期", translating to "Total Issue No. 262 China Geology" and "Issue No. 3, 1999".  Back in 2001 I assumed this meant volume 262 issue 3, but this is obviously not the case, and 26(3) and 262 are two different ways of referencing the same issue.  Counting back shows that the other three "total issues" are indeed 233, 242 and 238, although I'm not sure where in the issues people found these numbers and they're not very useful for navigating the archive.
