Saltopus ("hopping foot") is a genus of very small bipedal dinosauriform, roughly 60 centimeters (23 in) long, not much bigger than a rabbit, that was discovered in Scotland by Friedrich von Huene in 1910.[1] It was a late Triassic carnivore. Probably the size of a small cat, with hollow bones like those of a bird, it may have weighed in at around two pounds (one kilogram). Based on related forms, it probably had five-fingered hands and a long head with dozens of sharp teeth. To date, Saltopus is known only from very poor material, mostly hind limb fragments.
It has been variously identified as a saurischian (lizard-hipped) dinosaur, a more advanced theropod, and a close relative of the herrerasaurs, but its taxonomy is in dispute because only fragmentary remains have been recovered. Some researchers, such as Gregory S. Paul,[2] have suggested it may represent a juvenile specimen of a coelophysid theropod such as Coelophysis or Procompsognathus. Rauhut and Hungerbühler suggested it is a primitive dinosauriform, not a true dinosaur, closely related to Lagosuchus.[3] Benton and Walker found it to be a dinosauriform more derived than Pseudolagosuchus and basal to a clade composed of silesauridae and dinosauria.[4]
