Columbian mammoth
The Columbian mammoth shared its habitat with other now-extinct Pleistocene mammals such as "Glyptodon", "Smilodon", ground sloths, "Camelops", mastodons, horses, and bison. It did not live in Arctic Canada or Alaska, which was inhabited by woolly mammoths. Fossils of woolly and Columbian mammoths have been found in the same place in a few areas of North America where their ranges overlapped, including the Hot Springs Site. Whether the two species were sympatric and lived there simultaneously, or if the woolly mammoths entered southern areas when Columbian mammoth populations were absent is unknown. The Columbian mammoth coexisted with the other extinct proboscideans "Stegomastodon mirificus" and "Cuvieronius tropicus" at sites in Texas and New Mexico during the early Irvingtonian.
