Trogontherium
Trogontherium is an extinct genus of giant beavers, ranging from the Late Pliocene to the Late Pleistocene. It is not closely related to the North American giant beavers of the genus Castoroides. Fossils of Trogontherium have been found in Middle Pleistocene formations of England, mainland Europe, Yunnan, China, and Siberia, Russia. The last record of the taxon is from the Late Pleistocene of Manchuria near Harbin, which was deposited at approximately 40 Kyr. Its disappearance might be related to the arrival of hunter gatherers into the region.
