   “Artiodactyls first appear in the fossil record in the Eocene as small generalized creatures scarcely distinguishable from primitive insectivores or early carnivores. These were the paleodonts […]”

   “Another family, the Entelodontidae, flourished during the Oligocene and Miocene; they also were pig-like but somewhat larger than the paleodonts, with strong canine teeth and two toes on each foot. They disappeared during the Pliocene.”

   “The paleodonts had intermediate types of teeth. Primitive suines appeared in the Eocene.”

   “Wild and domesticated pigs are members of the paleodont artiodactyl family called Suidae, which is presumably the source of the popular hog-calling term "sooey."”
