Platyognathus

''Platyognathus'' is an extinct genus of protosuchian crocodylomorph. Fossils are known from the Early Jurassic Lower Lufeng Formation in Yunnan, China and belong to the type and only species, ''P. hsui''.
==Description==
The skull of ''Platyognathus'' is small, being about in length. The snout is narrow and shorter than the remainder of the skull, as indicated by the anterior position of the antorbital fenestra. Two teeth, dentaries 5 and 6, are enlarged into caniniforms in the lower jaw. Paired caniniform teeth are not seen in any other described crocodyliform taxa, but they have been recorded from an unidentified crocodyliform from the Lower Jurassic Kayenta Formation and from a protosuchid from the Lower Jurassic McCoy Brook Formation in Nova Scotia.〔
