Squirrel Facts: The First Squirrel

He lived in the North America during the Oligocene period, around 25 million years ago. Protosciurus was very similar in appearance, size, and skeletal structure to modern tree squirrels such as the eastern gray squirrel. The most complete specimen was found in Wyoming, and its remarkable similarity to modern tree squirrels has led to the theory that all of the present-day squirrels originated in North America with this species.

Do you ever have one of those mornings when
you just don't feel like getting out of bed?
