The Sauropodomorph Database Approacheth- "Yibinosaurus" and "Sugiyamasaurus"

The Sauropodomorph Database is almost ready to debut, but first here's a couple more entries to illustrate why I'm making the website.  The first is "Yibinosaurus", whose usual online information is limited to what Olshevsky wrote on the DML in 2001.  The other is "Sugiyamasaurus", which no one seems to have connected to Fukuititan yet. 

"Yibinosaurus" Ouyang vide anonymous, 2001
"Y. zhoui" Ouyang vide anonymous, 2001
Toarcian, Early Jurassic
Dongyuemiao Member of Ziliujing Formation, Sichuan, China
Material- (Chongqing Museum of Natural History coll.) specimen including dorsal vertebrae
Comments- This name originally appeared in a guidebook, with the taxon stated to be under study by Ouyang. Ouyang (2003) later mentioned it in his thesis as a new genus, which he places in an eponymous subfamily within Vulcanodontidae. As he also includes the more basal Gongxianosaurus in Vulcanodontidae, Ouyang's conception of the family may be more of a grade. Ouyang further notes the anterior dorsal neural spines are transversely expanded, which he believes indicates a possible relationship to taxa with bifurcated spines like Datousaurus. As Ouyang states "Yibinosaurus" is from the same locality as Gongxianosaurus, the dorsal vertebrae, 51 articulated caudal vertebrae, scapulae and ilium mentioned by Luo and Wang (1999) as Gongxianosaurus sp. nov. may be the "Yibinosaurus" material.

Titanosauriform tooth (FPDM coll.) from the Kitadani Formation, probably Fukuititan and/or "Sugiyamasaurus".  Scale = 10 mm.  After Goto et al. (2002).

Fukuititan Azuma and Shibata, 2010
?= "Sugiyamasaurus" Lambert, 1990
F. nipponensis Azuma and Shibata, 2010
Barremian, Early Cretaceous
Kitadani Formation of the Akaiwa Subgroup of the Tetori Group, Japan
Holotype- (FPDM V8468) three teeth, incomplete cervical neural arch, three distal caudal vertebrae (30 mm), proximal scapula, incomplete humeri (~910 mm), incomplete radii (~600 mm), metacarpal IV (295 mm), incomplete ischia, partial femur (~1.14 m), partial tibia, fibula, pedal phalanx (130 mm), fragments
Referred- ?(Sugiyama-ryu; "Sugiyamasaurus") three teeth (Azuma, 1991)
? five teeth (Azuma, 1991)
?(FPDM 1080417) tooth (Goto et al., 2002)
?(FPDM 1080417-A) tooth (Goto et al., 2002)
?(FPDM 1080757) tooth (Goto et al., 2002)
?(FPDM 1080920) tooth (Goto et al., 2002)
?(FPDM 1080942) tooth (Goto et al., 2002)
?(FPDM 1080944) tooth (Goto et al., 2002)
Diagnosis- (after Azuma and Shibata, 2010) tooth crowns asymmetrical and elongated with weak or absent labial groove and no lingual concavity; stalk-like cervical epipophyses; humerus proximal width 32% of length; metacarpal IV 48% of radial length; ischia slightly expanded distally.
Comments- The holotype was discovered in 2007 and described as a basal titanosauriform, though it has yet to be included in an analysis.
Teeth were first discovered from the quarry in 1989. Three teeth were informally called "Sugiyama-ryu", as found in Azuma (1991) and referred to Camarasauridae by this author and Dong et al. (1990). Lambert (1990) inappropriately made it into a genus name, listing it as "Sugiyamasaurus" in a childrens' book. Azuma (1991) lists five additional sauropod teeth as family indet. A and B, but he later (2003) placed all the teeth in Brachiosauridae. Kobayashi et al. (2006) referred the specimens to Titanosauriformes indet. based on near identical morphology to teeth from the Kuwajima Formation. Goto et al. (2002) illustrate a tooth. As the "Sugiyamasaurus" teeth are generally similar to Fukuititan's in morphology (D-shaped section; wrinkled enamel; parallel mesial and distal edges- Kobayashi et al., 2006) and found in the same quarry, they may belong to the same taxon. They should be examined for Fukuititan's supposed dental autapomorphies, which should be checked for positional variation and compared to other taxa as well.
