The Columbian mammoth (Mammuthus columbi) is an extinct species of mammoth that inhabited North America from southern Canada to Costa Rica during the Pleistocene epoch. The Columbian mammoth descended from Eurasian steppe mammoths that colonised North America during the Early Pleistocene around 1.5–1.3 million years ago, and later experienced hybridisation with the woolly mammoth lineage.

Mammoth tusks are among the largest known among proboscideans with some specimens over 4 m (13.1 ft) in length and likely 200 kg (440.9 lb) in weight with some historical reports suggesting tusks of Columbian mammoths could reach lengths of around 5 m (16.4 ft) substantially surpassing the largest known modern elephant tusks.
While the massive Columbian mammoth — which weighed over 22,000 pounds (10 tons) and could grow to be over 13 feet (4 meters) tall — lived across North America alongside the mastodon, its diet ...
An amateur fossil hunter discovered a 20,000-year-old Columbian mammoth tusk, the first intact find in Mississippi, revealing new insights into the state's prehistoric era.
The Columbian mammoth (Mammuthus columbi) was about 4 m (13.1 ft) tall at the shoulder but didn't weigh as much as other huge mammoths. Its average mass was 9.5 t (10.5 short tons) with one unusually large specimen about 12.5 t (13.8 short tons). [117] Columbian mammoths had very long tusks.
The massive Columbian mammoth, a proboscidean related to modern elephants that lived during the Pleistocene Epoch, could grow to be 15 feet at the shoulder and weigh over 10 tons.
