Paleontology studies began at Tule Springs in 1933 when the bones of a Columbian mammoth were discovered by quarry workers. [6] Other fossils found at the site include Camelops, ground sloth, dire wolf, Teratornis, Smilodon Fatalis and American lion, and range from 7,000 to 250,000 years old.

There are five living species: the jaguar, leopard, lion, snow leopard and tiger, as well as a number of extinct species, including the cave lion and American lion.
It is closely related and probably ancestral to the American lion (Panthera atrox). [2] The species ranged from Western Europe to eastern Beringia in North America, and was a prominent member of the mammoth steppe fauna, and an important apex predator across its range. It became extinct about 13,000 years ago. [4]
