Iranosauripus is an ichnogenus of dinosaur footprint found in the Shemshak Group of Iran that supposedly belonged to a theropod.[1] Iranosauripus supposedly existed during Middle Triassic to Early Jurassic,[2][3] although the first true dinosaurs, such as Eoraptor, did not exist until the Late Triassic;[4] the age of the specimens has since been refined to 201.6 to 183.0 Ma and further to 182.7 Ma.[5]

Discovery and naming

edit

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.[6] Abbassi (2014) described more specimens.[5]
