Description

Restoration

Paleoparadoxia is thought to have fed primarily on

sirenians, spending most of their lives walking across the sea bottom like marine hippos.[4] Studies on its habitat preference show that it favoured deep, offshore waters.[5]

Size estimates of P. tabatai vary, with the Tsuyama specimen measuring 215 cm (7.05 ft) in length, 80 cm (2.6 ft) in height, and 582 kg (1,283 lb) in body mass, and the other specimens measuring 1,048 kg (2,310 lb) and 3.2 metric tons (3.5 short tons) in body mass.[6]

Tokunaga 1939 named the genus Cornwallius but Reinhart 1959 synonymized it as a species of Paleoparadoxia.[7]
