This is an accepted version of this page Jaggermeryx is an extinct genus of semiaquatic anthracothere, ungulates related to hippopotamuses, from the Early Miocene Moghara Formation in Egypt.

"Some of my colleagues suggested naming the new species after Hollywood star Angelina Jolie, because she also has famous lips," said lead author Ellen Miller.

[5][7] At the site, six species of anthracotheres were discovered, but this sample was unlike other family members because of "a series of tiny holes on either side of its jaw that held the nerves providing sensation to the chin and lower lip.

Fossilized jawbones contain a number of mental foramina,[8] eight on each side of the jaw,[3] indicating that the species had very sensitive lips and a mobile snout.

[7][11] Judging by the low oxygen isotope values of its teeth, J. naida is believed to have been semiaquatic, likely spending most of the time when it was not feeding in the water, not unlike a hippopotamus.
