American Bison, Bison Bison Pleistocene Bison Priscus, Bison Wisent, Bison Antiquus, Occidentalis, Bison is a product of natural environmental change and inbreeding between migrated subspecies. Bison Priscus became extinct, but North America contained both Bison Antiquus, Latifrons and later, Bison Occidentalis. Antiquus stood 7.0 feet at the shoulders and weighed nearly 3,000 pounds. It’s hypothesized that what has come to be called the smaller but very successful American Bison was mostly derived from Occidentalis, but we don't really know. Both spread across North America from Canada to Texas, probably inbreeding, although Occidentalis seems to have been more successful. Largest of the Bison was Latifron Bison Bison,Latifrons, Bison Priscus or the large Steppe Bison Bison originally had a range stretching from Western Europe to the eastern tip of Asia. During the Ice Age, it crossed the land bridge and entered the Western Hemisphere. It is known to have established itself from Alaska to what is now Northern Washington State, but the distribution might have been more extensive. European cave drawings depict it including drawings of mortal battles with early Man. North American species alive or extinct probably derived from the Eurasian Bison Priscus. Latifrons was around 7.5 feet at the shoulders and weighed somewhat more than Antiquus.In point of fact, it is almost impossible to identify fossils between Bison Antiquus and Latifrons with the exception of the skull. Antiquus Point spread was almost one yard wide. More fossil ideas at https://fossilshopping.com
