Columbian mammoth
A large Pleistocene mammoth that coexisted with Paleoindians in North America.
The Columbian mammoth (*Mammuthus columbi*) was a species of mammoth that lived during the Pleistocene epoch, ranging across North America from southern Canada down to Costa Rica. It was one of the last mammoth species to exist, and the smaller pygmy mammoths of California’s Channel Islands evolved from them. Today, the closest living relative of the Columbian mammoth—and all mammoths—is the Asian elephant.
Standing 3.72 to 4.2 meters (12.2–13.8 feet) tall at the shoulder and weighing between 9.2 and 12.5 metric tons, the Columbian mammoth was among the largest mammoth species, bigger than both the woolly mammoth and the African bush elephant. It had long, curved tusks and four molars at any given time, which were replaced six times over its lifetime. Like modern elephants, it likely used its tusks and trunk for manipulating objects, fighting, and foraging. While bones, hair, dung, and stomach contents have been found, no preserved carcasses are known. This mammoth favored open parkland landscapes and fed on sedges, grasses, and other plants. It did not live in the Arctic regions of Canada—those areas were home to woolly mammoths—though the two species’ ranges may have overlapped, and genetic evidence suggests they interbred. Several sites contain the skeletons of multiple Columbian mammoths, possibly from mass deaths during droughts or from natural traps where individuals accumulated over time.
For a few thousand years before their extinction, Columbian mammoths shared North America with Paleoindians, the first humans in the Americas. These people hunted the mammoths for food, used their bones to make tools, and may have depicted them in ancient art. Columbian mammoth remains have been found alongside Clovis culture artifacts, and the Clovis people are thought to have been specialized mammoth hunters—though they may also have scavenged carcasses. The last Columbian mammoths died out around 12,000 years ago, as part of the Late Pleistocene extinction event that wiped out most large mammals in the Americas. They were among the last North American megafauna to go extinct. Their disappearance was likely caused by habitat loss from climate change, human hunting, or a combination of both.

Around 1725, enslaved Africans digging near the Stono River in South Carolina uncovered three or four molar teeth now known to be from Columbian mammoths. Briti

Lore & Background
The Columbian mammoth descended from Eurasian steppe mammoths that colonized North America during the Early Pleistocene around 1.5–1.3 million years ago, and later experienced hybridisation with the woolly mammoth lineage. It had long, curved tusks and four molars at a time, which were replaced six times during the lifetime of an individual. It most likely used its tusks and trunk like modern elephants—for manipulating objects, fighting, and foraging. Bones, hair, dung, and stomach contents have been discovered, but no preserved carcasses are known.
Reader's Guide
The Columbian mammoth is significant as one of the largest mammoth species and a key component of the Late Pleistocene megafauna of North America. It coexisted with Paleoindians for a few thousand years prior to its extinction, and its remains have been found in association with Clovis culture artifacts, suggesting that Clovis peoples were specialized mammoth hunters or scavengers. The species became extinct about 12,000 years ago as part of the Late Pleistocene extinction event, likely due to habitat loss from climate change, human hunting, or both. Its taxonomy was clarified in the 20th century, with M. columbi and M. exilis recognized as the only mammoth species endemic to the Americas. The first identification of its fossils in North America was made by enslaved Africans and noted by Mark Catesby in 1743, marking the first technical identification of any fossil animal in North America.
Did You Know?
- The Columbian mammoth was first scientifically described in 1857 by Scottish naturalist Hugh Falconer, who named it Elephas columbi after Christopher Columbus.
- Around 1725, enslaved Africans in South Carolina unearthed Columbian mammoth molars and identified them as elephant teeth, marking the first technical identification of a fossil animal in North America.
- The Columbian mammoth did not live in Arctic regions of Canada; those areas were inhabited by woolly mammoths, though the two species may have overlapped and interbred.
- The pygmy mammoth evolved from Columbian mammoths on the Channel Islands of California.
