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.
The last reliable dates of the Columbian mammoth date to around 12,500 years ago. [56] Columbian mammoths became extinct as part of the end-Pleistocene extinction event where most large mammals across the Americas became extinct approximately simultaneously at the end of the Late Pleistocene.

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). [ 115 ]
The tusk of this mammoth, in particular, belongs to a Columbian mammoth. These animals were larger than the stereotypical woolly types. Reaching 13 feet tall at the shoulder, these giants ...
The tusk Templeton found is so large because it came from a Columbian mammoth, an animal that could grow up to 15 feet tall at the shoulder and weigh in excess of 10 tons.
The pygmy mammoths of the Channel Islands (California) evolved from Columbian mammoths. The closest extant relative of the Columbian and other mammoths is the Asian elephant. Reaching 4 m (13 ft) at the shoulders and 8–10 tonnes (18,000–22,000 lb) in weight, the Columbian mammoth was one of the largest species of mammoth.
The tusk Templeton found came from a Columbian mammoth that lived between 10,000 and 20,000 years ago, not the more famous, but smaller woolly mammoth. Columbian mammoths could grow up to 15 feet ...
The Waco Mammoth National Monument is the site of the only known remains of a herd of "Columbian Mammoths." [14] The site also includes "in situ" fossils of a camel, a bull mammoth, and female mammoths. The fossils are "in situ", meaning they are in the original place of initial discovery.
