| Pezosiren portelli Domning, 2001 |
Pezosiren portelli is the name given to what is thought to be an early sirenian represented by a Jamaican fossil skeleton, described in 2001 by Daryl Domning, a marine mammal paleontologist at Howard University in Washington, DC. It is believed to have lived 50 million years ago, perhaps with a hippopotamus-like amphibious lifestyle.
It had the skull and basic body shared by most modern sirenians, like manatees and dugongs, but also had four normal limbs, still adapted for walking on land.
