The size estimates suggest that American mastodon males were on average heavier than any living elephant species; they were typically larger than Asian elephants and African forest elephants of both sexes but shorter than male African bush elephants.
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.
The skull of the young adult (around 24-26 years old in African elephant tooth wear equivalent years) AM 02 from Auchas, Namibia, was around the size of that of a 10 year old American mastodon, [5] around 60 centimetres (2.0 ft) in maximum length. [6]
The largest extant proboscidean is the African bush elephant, with a world record of size of 4 m (13.1 ft) at the shoulder and 10.4 t (11.5 short tons). [2] In addition to their enormous size, later proboscideans are distinguished by tusks and long, muscular trunks, which were less developed or absent in early proboscideans.
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.
Mastodons, large mammals similar to both elephants and mammoths, roamed North America from around 3.5 million years ago until 10,500 years ago.
This mammoth was about the same size or somewhat smaller than the earlier mammoth species M. meridionalis and M. trogontherii, but was larger than the modern African bush elephant and the woolly mammoth, both of which reached about 2.67 to 3.49 m (8 ft 9 in to 11 ft 5 in) at the shoulder. [23] [24] Males were generally larger and more robust.
