Alligator, 80 million years
The alligator’s ancestors evolved about 245 million years ago, however, the closest relatives to alligators, the crocodilians, appeared 80 million years ago, which are also related to crocodiles. Even though many animals went extinct in this time period, it’s still unknown why the alligators survived.
