''Pterospondylus'' (meaning "winged vertebra") is a dubious genus of theropod dinosaur from the Late Triassic. It was a coelophysoid theropod which lived in what is now Germany (Trossingen Formation). The type species, ''Pterospondylus trielbae'', was described by Jaekel in 1913-14 for a single back vertebra.〔Jaekel, O. (1913-14). Über die Wirbeltierefunde in der oberen Trias von Halberstadt. ''Paläontologische Zeitschrift'' 1:155-215.〕 Sometimes, it is aligned with ''Procompsognathus'',〔von Huene, F. (1932). Die fossile Reptil-Ordnung Saurischia, ihte Entwicklung und Geschichte. ''Monographien zur Geologie und Palaeontologie'' 1(4). 361 p. ()〕 or even considered to be synonymous with it,〔Steel, R. (1970). Part 14. Saurischia. ''Handbuch der Paläoherpetologie''. Gustav Fischer Verlag:Stuttgart, 1-87.〕 despite being based on a vertebra that is twice the size of the corresponding bone in ''Procompsognathus''.〔Ostrom, J.H. (1981). ''Procompsognathus'' — theropod or thecodont? ''Palaeontographica'' Abstract A, 175(4-6):179-195.〕 ==References==
