Pterospondylus (meaning "winged vertebra") is a dubious genus of theropod dinosaur from the Late Triassic. It was a coelophysid theropod which lived in what is now Germany ( Trossingen Formation). The type species, Pterospondylus trielbae, (derived from "Tri", in reference to the Triassic period, and "Elba", for the Elbe River area [1]), was described by Jaekel in 1913–14 for a single back vertebra found inside the shell of the Proganochelys turtle. [1] Sometimes, it is aligned with Procompsognathus, [2] or even considered to be synonymous with it, [3] despite being based on a vertebra that is twice the size of the corresponding bone in Procompsognathus. [4] P. trielbae has no diagnostic features and is therefore considered a nomen dubium. [5]
