The Columbian mammoth was a savanna and grassland inhabitant, similar to the modern African elephant. Large males ranged from 3.7–4.0 m (12–13 ft) and weighed between 7–9 metric tons (7.7–9.9 short tons) with spiraled tusks that could grow up to 4.25 meters (13.9 ft) long. 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. The average Columbian mammoth ate 300 pounds of vegetation a day. Hair believed to have belonged to the Columbian mammoth has been discovered in the Bechan Cave, Utah, where mammoth dung has also been found. Some of this hair is coarse, and identical to that known to belong to woolly mammoths. Since this location is so far south, it is unlikely the hair belonged to woolly mammoth. The distribution and density of this fur on the living animal is unknown.
