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.
This list of fictional pachyderms is a subsidiary to the List of fictional ungulates.Characters from various fictional works are organized by medium. Outside strict biological classification, [a] the term "pachyderm" is commonly used to describe elephants, rhinoceroses, tapirs, and hippopotamuses; this list also includes extinct mammals such as woolly mammoths, mastodons, etc.
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 ...
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.
An amateur fossil hunter has uncovered a 7 ft-long, fully intact mammoth tusk in a creek near a Mississippi river stream, a world-first discovery that sheds more light on the region’s ecology ...
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.
Other descendants of the straight-tusked elephant existed in Cyprus. Dwarf elephants of uncertain descent lived in Crete, Cyclades and Dodecanese, while dwarf mammoths are known to have lived in Sardinia. [26] The Columbian mammoth colonised the Channel Islands and evolved into the pygmy mammoth. This species reached a height of 1.2–1.8 m (4 ...
