Epicyon - Facts and Figures

Epicyon - Facts and Figures Name: Epicyon (Greek for more than a dog); pronounced EPP-ih-SIGH-on Habitat: Plains of North America Historical Epoch: Middle-Late Miocene (15-5 million years ago) Size and Weight: About five feet long and 200-300 pounds Diet: Meat Distinguishing Characteristics: Large size; quadrupedal posture; big-cat-like head About Epicyon Possibly the largest prehistoric dog that ever lived, Epicyon was a true canid, belonging to the same general family as wolves, hyenas and modern dogs- and was thus a different beast altogether from the non-canid creodont mammals (typified by the giant Sarkastodon) that ruled the North American plains for millions of years before the Miocene epoch. The largest species of Epicyon weighed in the neighborhood of 200 to 300 pounds- as much as, or more than, a full-grown humanand it possessed unusually powerful jaws and teeth, which made its head look more like that of a big cat than a dog or wolf. However, paleontologists dont know much about Epicyons feeding habits:  this megafauna mammal  may have hunted alone or in packs, and it may even have subsisted exclusively on already-dead carcasses, like  a modern hyena. Epicyon is known by three species, all of which were discovered in western North America in the course of the 19th and 20th centuries. The lightest variant, Epicyon saevus, was named by the famous American paleontologist Joseph Leidy, and for a time was classified as a species of Aelurodon; adults only weighed about 100 pounds fully grown. E. haydeni was also named by Leidy, and has been synonymized not only with Aelurodon, but with the even more obscure Osteoborus and Tephrocyon as well; this was the largest Epicyon species, weighing more than 300 pounds. The most recent addition to the Epicyon family, E. aelurodontoides, was discovered in Kansas in 1999; you can tell by its species name that it was also close kin to Aelurodon!
