Saltopus elginensis
Taxonomy
Saltopus elginensis was named by Huene (1910). Its type specimen is NHMUK (formerly BMNH) R.3915, a partial skeleton (partial postcranial skeleton), and it is a mold. Its type locality is Lossiemouth West & East Quarries, Elgin, which is in a Carnian/Norian dune sandstone/sandstone in the Lossiemouth Sandstone Formation of the United Kingdom.
It was considered a nomen dubium by Welles (1984); it was considered a nomen dubium by Rauhut and Hungerbühler (2000).

M. J. Benton and A. D. Walker 2011 | Saltopus elginensis possesses synapomorphies of Archosauria, Avemetatarsalia, Dinosauromorpha, and Dinosauriformes, successive nested clades (see below). Comparison with other basal dinosauromorphs shows that Saltopus lacks the fused astragalocalcaneum and functionally didactyl pes of Lagerpeton (Sereno & Arcucci 1993), the robust pubis and reduced calcaneum of Pseudolagosuchus (Arcucci 1987), and probably the two fused dorsosacral vertebrae, elongate forelimb, very short iliac blade, and reduced calcaneum of Silesaurus (Dzik 2003). Saltopus shows no unique apomorphies in comparison with these and other taxa, so it could be regarded as a nomen dubium until a skull, or some better preserved postcranial remains come to light. However, its character coding (Table 2) is unique, being replicated in no other Triassic archosaur (Brusatte et al. 2010), and so the genus and species is valid. |
