Mastodon
Summary
A mastodon (μαστός 'breast' + ὀδούς 'tooth') is any proboscidean belonging to the extinct genus Mammut. Mastodons inhabited North and Central America from the late Miocene up to their extinction at the end of the Pleistocene 10,000 to 11,000 years ago.
Mastodons are the most recent members of the family Mammutidae, which diverged from the ancestors of elephants at least 25 million years ago.
M. americanum, the American mastodon, and M. pacificus, the Pacific mastodon, are the youngest and best-known species of the genus. They lived in herds and were predominantly forest-dwelling animals. M. americanum is inferred to have had a browsing diet with a preference for woody material, distinct from that of the contemporary Columbian mammoth. Mastodons became extinct as part of the Quaternary extinction event that exterminated most Pleistocene megafauna present in the Americas, believed to have been caused by a combination of climate changes at the end of the Pleistocene and hunting by recently arrived Paleo-Indians, as evidenced by a number of kill sites where mastodon remains are associated with human artifacts.
A Dutch tenant farmer found the first recorded remnant of Mammut, a tooth some in weight, in the village of Claverack, New York, in 1705. The mystery animal became known as the "incognitum". In 1739 French soldiers at present-day Big Bone Lick State Park, Kentucky, found the first bones to be collected and studied scientifically. They carried them to the Mississippi River, from where they were transported to the National Museum of Natural History in Paris. Similar teeth were found in South Carolina, and some of the African slaves there supposedly recognized them as being similar to the teeth of African elephants. There soon followed discoveries of complete bones and tusks in Ohio. People started referring to the "incognitum" as a "mammoth", like the ones that were being dug out in Siberia – in 1796 the French anatomist Georges Cuvier proposed the radical idea that mammoths were not simply elephant bones that had been somehow transported north, but a species which no longer existed.
