Abstract

The isolated upper molar M2 of the Early Pleistocene beaver Trogontherium cuvieri Fischer von Waldheim, 1814 is described from the Khondu locality in the Churapchinsky district of Yakutia. The internal structure of the tooth was studied using computed tomography and the wear process was reconstructed based on a series of CT cross-sections. The described find supplements the extremely scanty information on the Pleistocene Castoridae in Eastern Siberia.
