antelope (Bison antiquus)

Bison antiquus, commonly known as the ancient or long-horned bison, was a prehistoric ancestor of the modern bison. It lived in North America during the late Pleistocene epoch, around 10,000 to 100,000 years ago. Larger than today's bison, Bison antiquus had massive skulls and impressive, curved horns. It was a herbivore that roamed vast plains and woodlands, forming herds for protection and social interaction. Fossil evidence of Bison antiquus helps scientists understand past ecosystems and climate changes, as well as the evolution of North American megafauna.
