| | FAQ Alligators and Their Kin |
 | | Although this family has existed since the upper Triassic Period, over 200 million years ago, reptiles which can definitely be classed as modern alligators, caimans, gavials, and crocodiles only appear in the fossil record about 80 million years ago. |
 | | Today, Family Crocodylidae contains three subfamilies: Alligatorinae (alligators and caimans), Crocodylinae (crocodiles), and Gavialinae (gharials or gavials). |
 | | A fourth subfamily, Tomistominae, containing a single species, the False Gharial, Tomistoma shlegelii, has been proposed. |
