They then colonised the Japanese archipelago, evolving into Palaeoloxodon naumanni by 400,000 years ago. The Middle Pleistocene vertebrate fauna from Khok Sung (Nakhon Ratchasima, Thailand): biochronological and paleobiogeographical implications. Pl.

'An adult straight-tusked elephant would easily have been able to rest its chin on the back of a bull African savannah elephant.' [7] The youngest dates for the species are around 24 kyr Before Present, during the early stages of the Last Glacial Maximum. Today, the largest land mammal is the African elephant, which stands around 3.3 metres at the shoulder and weighs up to seven tonnes. (eds.). Heinrich Edmund Naumann researched and reported these fossils in “Ueber japanische Elephanten der Vorzeit” (1882). Extinct Doves, Pigeons, and Dodos. They were able to show that the ancestor species, Palaeoloxodon recki, dispersed from Africa into the Near East roughly 780,000 years ago. The Japanese species survived possibly a little longer afterwards. You must be over the age of 13. The paper argues that P. antiquus is closer to L. cyclotis than L. cyclotis is to the African bush elephant, L. africana, thus invalidating the genus Loxodonta as currently recognized. [3][dead link][dubious – discuss] The species had a pair of long twisted tusks and a bulge on the head. Taxonomy & Nomenclature. Maturation of a strong POC in Palaeoloxodon antiquus, P. namadicus and P. cf. • P. turkmenicus and P. naumanni may represent plesiomorphic early offshoot of Palaeoloxodon evolution in Asia. Running around their head was a crest of bone jutting forward, like a headband.

Deinsea 9, 421-428. Straight-tusked elephants were some of the largest land mammals ever to have existed, but no one has been quite sure just how many of the now-extinct species existed throughout Africa, Europe and Asia during the last million years. Palaeoloxodon is known informally as the "straight-tusked elephant" because of the straight tusks of Elephas (Palaeoloxodon) antiquus.
