Western Camel, Camelops hesternus. The camel family evolved in North America during the Middle Eocene Epoch, 40-45 million years ago. Many different species of camels were present in North America during the various geologic ages. Camels migrated to Asia 4-5 million years ago across the Bering land bridge. All camel species in North America were extinct by 11,000 years ago.

Gastornis, a large flightless bird from the Eocene of Wyoming. Gastornis were very large birds, & have traditionally been considered to be predators of small mammals. However, several lines of evidence, including the lack of hooked claws in known Gastornis footprints & studies of their beak structure, have caused scientists to re-interpret these birds as herbivores which probably fed on tough plant material & seeds

Gastornis giganteus, the Terror Bird, Paleocene and Eocene Period of the Cenozoic Million Years Ago

Basilosaurus is Latin for “King Lizard”, but actually they are mammals. Another common name “Zeuglodon” means ‘Yoke Tooth,’ because its triangular teeth resemble a yoke. It was 50-70 ft. (18M) in length and was one of the first whales to become extremely large. This Archaeocete Whale lived 45-34 Million Years Ago in the late Eocene Period. It hunted and raised its young in warm shallow seas.
