It was the largest and heaviest bovid ever to live in North America.[2] It thrived in North America for about 200,000 years, but became extinct some 20,000–30,000 years ago, at the beginning of the last glacial maximum.

Because only skulls and horns of this species have been found well preserved, the size of B. latifrons is currently not clearly known. Based on leg bones, the mass of B. latifrons has been estimated to be 25-50 percent larger than that of modern B. bison, making it undoubtedly one of the largest-ever ruminants.[3][4]
