Elephantidae is a family of large, herbivorous proboscidean mammals collectively called elephants and mammoths. These are large terrestrial mammals with a snout modified into a trunk and teeth modified into tusks. Most genera and species in the family are extinct. Only two genera, Loxodonta (African elephants) and Elephas (Asian elephants), are ...
The family Elephantidae existed 6 million years ago in Africa and includes the modern elephants and the mammoths. Among many now-extinct clades, the mastodon (Mammut) is only a distant relative of the mammoths and part of the separate family Mammutidae, which diverged 25 million years before the mammoths evolved.

[9] [10] [11] Mammoths (Mammuthus) are nested within living elephants as they are more closely related to Asian elephants than to African elephants. [12] Another extinct genus of elephant, Palaeoloxodon , is also recognised, which appears to have close affinities with African elephants and to have hybridised with African forest elephants.
The slaves' identification of the teeth as elephantine is evidence that this discovery was of mammoth rather than mastodon fossils, whose cusped teeth are very distinct from elephants'. [16] Between 1775 and 1780, Thomas Jefferson conferred with leaders of the Delaware Indians in Virginia about the fossils of Big Bone Lick, of what is now Kentucky.
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. [36] The heads of ...
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 ...

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 until their extinction at beginning of the Holocene, around 11,000 years ago.
