Crocodylia - skulls of American crocodile (Crocodylus acutus), American alligator (Alligator mississippiensis), and crocodile sp. Similar animals began to show up in the fossil record as much as 230mya, but modern-day members of Crocodylia have remain largely unchanged for the last 80my, and out-survived the dinosaurs that perished during the mass extinction event signaling the end of the Cretaceous period 66mya.
This is sorta crazy, considering modern-day humans diverged from our closest relatives only about 500,000 years ago. Lol.
