Saltopus elginensis (von Huene 1910) Late Triassic (~210 mya), ~60 cm long, is known from a spine and pelvis in dorsal view plus a few limb parts. The curved femur, open space between the radius and ulna and the pedal bone were most similar to those of Gracilisuchus.
Von Huene (1910) found six sacrals. Benton and Walker (2011) found two sacrals twice as long as the adjoining dorsals and caudals. I found four sacrals (as in the sister taxon, Scleromochlus), each the same length as adjoining vertebrae, plus the lower pelvic elements. The caudals were longer, producing a longer tail.
The scapula was larger. The anterior process of the pelvis was larger. The tibia was longer than the femur and the toes were relatively longer.
No basal dinosaur captures as many sacral vertebrae between the ilia. No fenestrasaur or dinosaur had such a large space between the ulna and radius. In consideration of the elongation of the pelvis, tibia and toes, Saltopus was a bipedal croc, like Scleromochlus.
