Alligatoroidea

This is a taxonomic superfamily. It is thought to have split from other Crocodylians between 100 million to 80 million years ago, back in the Cretaceous period. Thus when someone tells you that alligators haven't changed since the Jurassic period, don't believe them.https://en.wikipedia.org/w/index.php?title=Alligatoroidea&oldid=1137286425https://en.wikipedia.org/w/index.php?title=Alligatoridae&oldid=1121478934
