Batrachopus is an extinct ichnotaxon of pseudosuchian that lived during the Triassic-Cretaceous periods between 235-100 million years ago.[1] It was first named by Edward Hitchcock in 1845.[2] The first known Batrachopus footprints were discovered in 1843 in the Newark Group (Massachusetts).[3] Batrachopus grandis from the Early Cretaceous Jinju Formation and Haman Formation of South Korea, initially considered as a pterosaur track until it was redescribed as an ichnospecies within the ichnogenus Batrachopus as a bipedal crocodylomorph, might instead represent trace fossils of a therizinosaur.[4]
