The name of the extinct mammal is Jaggermeryx naida, or Jagger’s water nymph. It was sort of a mix between a slender hippo and a long legged pig. It lived about 19 million years ago in Egypt. After scientists studied the bone structure of the skull, it was determined to have a large tongue and lips. They considered naming it after Angelina Jolie, but thought she wouldn't be pleased, so they switched to Mick Jagger. Link
