A mastodon (mastós 'breast' + odoús 'tooth') is a member of the genus Mammut (German for 'mammoth'), which was endemic to North America and lived from the late Miocene to the early Holocene. Mastodons belong to the order Proboscidea , the same order as elephants and mammoths (which belong to the family Elephantidae ).
Mammutidae is an extinct family of proboscideans belonging to Elephantimorpha.It is best known for the mastodons (genus Mammut), which inhabited North America from the Late Miocene (around 8 million years ago) until their extinction at the beginning of the Holocene, around 11,000 years ago.
Mammoth tusks are among the largest known among proboscideans with some specimens over 4 m (13.1 ft) in length and likely 200 kg (440.9 lb) in weight with some historical reports suggesting tusks of Columbian mammoths could reach lengths of around 5 m (16.4 ft) substantially surpassing the largest known modern elephant tusks.
Finding any part of a tusk is rare, but mammoth tusks are especially so. It's much more common to find mastodon fossils, because the animals could live in a variety of habitats, whereas mammoths ...

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 woolly mammoth project, for instance, has sequenced the genomes of both the Asian elephant and the African elephant; has developed induced pluripotent stem cells with the ability to ...
