What is "crocodylidae"

The Crocodylidae family of crocodylians includes the true crocodiles which are the members of the subfamily Crocodylinae and the Tomistoma genus. Currently, the family includes two subfamilies, Crocodylinae and Tomistominae, with the latter being a subject of controversy whether it is a crocodile or belongs to the family Gavialidae. Further genetic analysis has to be done to come to a final conclusion.
