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

Giganotosaurus

Giganotosaurus

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.

A new fossil discovery, named Heteronectes (meaning 'different swimmer'), was found in 50 million year old marine rocks from northern Italy. This study provides the first detailed description of a primitive flatfish, revealing that the migrated eye had not yet crossed to the opposite side of the skull in early members of this group.
