The Columbian Mammoth (Mammuthus columbi) is an extinct species of elephant of the Quaternary period that appeared in North America (in the present United States and to as far south as Nicaragua and Honduras) during the late Pleistocene. It is believed by some authorities to be the same species as its slightly larger cousin, M. imperator, because of their similarities in fossil location and size.[citation needed]
The Columbian Mammoth was one of the last members of the American megafauna to go extinct, with the date of disappearance generally set at approximately 12,500 years ago.[1] However, several specimens have been dated to 9,000 years ago or less and one near Nashville, Tennessee was reliably dated to only about 7,800 years ago.[citation needed]

The Columbian mammoth was one of the largest of the mammoth species and also one of the largest elephants to have ever lived, measuring 4 metres (13 ft) tall and weighing up to 10 metric tons (11 short tons). It was 10.7 feet (3.3 m) long at the shoulder, and had a head that accounted for 12 to 25 percent of its body weight.[2] It had impressive, spiralled tusks which typically extended to 6.5 feet (2.0 m). A pair of Columbian Mammoth tusks discovered in central Texas was the largest ever found for any member of the elephant family: 16 feet (4.9 m) long.[citation needed]
It was an herbivore, with a diet consisting of varied plant life ranging from grasses to conifers. It is also theorized that the Columbian Mammoth ate the giant fruits of North America such as the Osage-orange, Kentucky coffee and Honey locust as there was no other large herbivore in North America then that could ingest these fruits. Using studies of African elephants, it has been estimated that a large male would have eaten approximately 700 pounds (320 kg) of plant material daily.[citation needed] The average Columbian mammoth ate 300 pounds of vegetation a day.
The remains of Columbian Mammoths were discovered in the La Brea Tar Pits, located in Los Angeles, California, and the skeleton of one of them is on exhibit in that site's museum. The Waco Mammoth Site in Waco, TX holds the record for the largest known concentration of skeletons of mammoths believed to have died in the same event.[3] This mammoth also lived in Mexico, where its remains are very common. A large individual is the central exhibit in the Regional Museum of Guadalajara, in the Mexican state of Jalisco.[citation needed]
In 1998, the Washington State Legislature approved the Columbian Mammoth as the State Fossil.[4]
A Columbian Mammoth appeared in Episode 12 of the ITV television series Primeval. It went through an anomaly and wreaked havoc on the M25. It also stars in the BBC serial Wild New World, known as Prehistoric America in the US. It also made a brief appearance in Monsters we Met in stock footage from Prehistoric America. It also appeared as a beast from L.A. 10000 B.C. that fought early man.
