So how does it fare? Pretty well, though Herrerasauridae, Megalosauria, Spinosauridae and Tyrannosauridae have definitions that fail. There are some uncertainties based on the unclear position of ornithomimosaurs, and due to the date there are no taxa between Archaeopteryx and ornithothoracines. But overall, not bad.
Among the "Theropod Odds and Ends", Taquet's (1984) taxon has yet to be redescribed but seems to be a coelophysoid, "Labrosaurus" ferox is agreed to be an allosaurid/Allosaurus specimen and maybe a portion of the A. fragilis neotype. (Magnosaurus) nethercombensis is a megalosauroid, possibly afrovenatorine. (Duriavenator) hesperis is a megalosaurid. Xuanhanosaurus seems to be a metriacanthosaurid. Iliosuchus may be a basal tyrannosauroid or other basal coelurosaurian, which is debated for taxa known from far more than only ilia. Stokesosaurus is universally agreed to be a basal tyrannosauroid. Finally, Segisaurus is agreed to be a coelophysoid closer to Coelophysis than Dilophosaurus.
Twenty-third (II) and twenty-second (III) dentary tooth of holotype of Segnosaurus galbinensis (IGM 10/80), after Zanno et al. (2016). Note the weird lingual carina (lc). |
