Eusuchia ("true crocodiles") is a clade of crocodylomorphs that first appears in the Early Cretaceous with Hylaeochampsa.[1] All living crocodilian species are eusuchians, as are many extinct forms.
Description[]
Unlike primitive crocodylomorphs, eusuchians possess a secondary bony palate.[1] This feature enables crocodiles and alligators to safely breathe in through their nostrils while the rest of the head (including the mouth) remains submerged.[2]
