Daeodon was an entelodont a group of prehistoric hoofed mammals that resembled pigs. In fact, Daeodon was once known as Dinohyuswhich means Terrible Pig Daeodons had huge heads that could measure up to three feet long, and they were omnivores, which means they ate plants and other animals. They ranged across the United States between 20 and 30 million years ago. History: Daeodon was discovered in 1878 by paleontologist Edward Drinker Cope but was not classified as an entelodont until some 30 years later. Many other genera, including Dinohyus, would later be folded into the Daeodon genus. Daeodon shoshonensis was the largest known entelodont, standing almost six feet tall at the shoulder.
