Iranosauripus

Iranosauripus is an ichnogenus of dinosaur footprint found in the Shemshak Group of Iran that supposedly belonged to a theropod. Iranosauripus supposedly existed during Middle Triassic to Early Jurassic, although the first true dinosaurs, such as Eoraptor, did not exist until the Late Triassic; the age of the specimens has since been refined to 201.6 to 183.0 Ma and further to 182.7 Ma.

Discovery and naming

The first known footprints were discovered in 1975 in the Shemshak Group in the Alborz Mountains of Iran by Albert-Félix de Lapparent and M. A. Nowgol Sadat, and the type ichnospecies, I. zerabensis was also named in 1975. Abbassi described more specimens.
