the two extant genera of true crocodiles, "crocodylus" and "osteolaemus", are in the subfamily crocodylinae. even according to traditional classification, the "tomistoma" is not a true crocodile, though it is a member of the family crocodylidae. latest molecular evidence points to an even greater difference, creating the possibility that in fact "tomistoma" is genetically closer to the gharial than true crocodiles. if proven, the species will be classified under the family gavialidae.
