“ | They don't come much meaner than this. A giant Enteledon, the bully of the plains. These are distant relatives of the pig. Two meters tall, aggressive, and built like tanks, but with a brain no bigger than an orange. | „ |
— Allen Johnson, about Entelodon in The Big, The Bad, and The Ugly |
Entelodon (name meaning "Complete Teeth"), often nicknamed the "Hell Hog", is a genus of entelodont artiodactyl that originated during the Middle Eocene epoch in what is now Eurasia. Standing 2 meters tall, measuring 3 meters long, and weighing a ton, these omnivorous mammals are distantly related to modern day swine.
In the Series 3 episode "The Big, the Bad, and the Ugly," a group of Entelodon (consisting of four adults and three juveniles) were brought to the park from Late Oligocene Mongolia, 25 million years ago.
