Pachagnathus ("earth jaw") is an extinct genus of non-pterodactyloid pterosaur from the late Norian–early Rhaetian-aged Quebrada del Barro Formation of Argentina. It lived in the Late Triassic period (217-201 million years ago),[1] and is one of the only known definitive Triassic pterosaurs from the southern hemisphere (along with the contemporaneous and related Yelaphomte). It is also one of the few known continental Triassic pterosaurs, indicating that the absence of early pterosaurs in both the southern hemisphere and terrestrial environments is likely a sampling bias, and not a true absence.
