There is one species of Polar Bear, or (Ursus maritimus). In the past, before they were fully studied and researched, there was some confusion as to the number of subspecies. In 1774 when the Polar Bear was first identified, it was considered two subspecies. The first to be documented was named (Ursus maritimus maritimus) by Constance Phipps. The second was named (Ursus maritimus marinus) by Peter Pallas in 1776. Both of these subspecies were later invalidated. Also fossil history leaves a clue about Polar Bears, the (Ursus maritimus tyrannus) was a subspecies that was much larger than Polar Bears of today. These Polar Bears passed into extinction, about 100,000 years ago, sometime in the Pleistocene. For more details, please see the sites listed below.
