Hylaeochampsa

''Hylaeochampsa'' is an extinct genus of eusuchian crocodylomorph. It is known only from a partial skull recovered from Barremian-age rocks of the Lower Cretaceous Vectis Formation (Wealden Group) of the Isle of Wight. This skull, BMNH R 177, is short and wide, with a eusuchian-like palate and inferred enlarged posterior teeth that would have been suitable for crushing. ''Hylaochampsa'' was described by Richard Owen in 1874, with ''H. vectiana'' as the type species. It may be the same genus as the slightly older ''Heterosuchus'', inferred to have been of similar evolutionary grade, but there is no overlapping material as ''Heterosuchus'' is known only from vertebrae. If the two could be shown to be synonyms, ''Hylaeochampsa'' would have priority because it is the older name. ''Hylaeochampsa'' is the type genus of the family Hylaeochampsidae, which also includes ''Iharkutosuchus'' from the Late Cretaceous of Hungary. James Clark and Mark Norell positioned it as the sister group to Crocodylia. ''Hylaeochampsa'' is currently the oldest known eusuchian.
