Moeritherium lived in North Africa about 50 million years ago in the Miocene.
They stood little more than two feet tall and likely ate water plants in ponds similarly to hippopotamuses.
Palaeomastodons stood little more than 6 feet tall and lived from around 30 to
34 million years ago.
Four tusked Mastodon
The Trilophodon stood over 8 feet tall and lived in Africa,
Europe, Asia and North America from the Miocene (26 million years ago) to
the Pleistocene epoch (2 million years ago) .
Tetrabelodon lived in
North Africa, Europe and Asia during the Miocene (24 million to 5 million
years ago) and the early Pliocene (5 million to 1.8 million years ago).
Tetrabelodons had four tusks and one species stood more than 15 feet tall.
The Dinotherium lived in Europe, Africa and Asia from
around 20 million years ago to around just a few million years ago in the
Miocene and the Pliocene periods.
Long Jawed Mastodon
stood about 4 1/2 ft high, had four tusks and
lived in the Oligocene epoch (from about 33.7 to 23.8 million years
ago), part of the Tertiary Period in the Cenozoic Era.
During the Oligocene epoch, the first Mastodons lived
in Africa and their larger descendants spread over Asia, Europe and finally
to Northern America about 15 million years ago in the Miocene (23.8 to 5.3
million years ago.) The last Long-jawed Mastodons lived in North
America and became extinct near the end of the Pleistocene (1.8 million to
11,000 years ago)
