Pachygenys ("thick jaw") is a genus of scincomorphan lizard from the Lower Cretaceous of Japan. Its name is composed of the Greek words παχυς pachys ("thick") and γένυς génys ("jaw").[1]
Description[]
Pachygenys has a few defining characters, of which include a distinct foreshortening of the dentary tooth row and a reduced amount of dentary teeth. P.adachii differs from P.thlastesa in a few aspects; P.adachii has a shorter tooth row than P.thlastesa, as well as anterior and middle teeth that have uncuspid crowns and posterior teeth with simple, uncuspid conical crowns.[1]
