Prehistoric Predators is a 2007 National Geographic Channel program based on different predators that lived in the Cenozoic era, including Smilodon and C. megalodon. The series investigated how such beasts hunted and fought other creatures, and what drove them to extinction.
The huge terror birds of South and North America, Kelenken and Titanis, are both shown as apex predators. Kelenken is shown to eat Homalodotherium, glyptodonts, and rodents, and Titanis is shown coming into competition with additional predators Smilodon gracilis and Canis edwardii, and is also shown to eat horses.
Archaeotherium was the largest and most powerful beast of the badlands until the bear dogs arrived, and is depicted evolving into the even larger Daeodon (or Dinohyus) in order to survive against the new threat.

The only animal who would attack an Archaeotherium was Hyaenodon, with its powerful razor jaws, until bear dogs arrived on the continent, driving both to extinction.
