Konobelodon is an extinct genus of amebelodont from southern Europe, China, and North America.

Taxonomy

Restoration of K. britti

Konobelodon was originally coined as a subgenus of Amebelodon,[2] and was subsequently elevated to full generic rank in a 2014 re-appraisal of "Mastodon" atticus.[3] Within Amebelodontinae, Konobelodon is closely related to Platybelodon and Torynobelodon.[1] The genus Konobelodon likely originated in eastern Eurasia, with K. robustus being known from the Liushu Formation in the Gansu Province of China.[4] Under this hypothesis, it diverged via separate migrations westward into Europe and western Asia, represented by K. atticus, and eastward into North America, where the genus arrived c. 7 Ma and survived until the very end of the Miocene.[3]

Description

As shovel-tusked amebelodonts, Konobelodon has two pairs of tusks, one growing from the upper jaw and a second from the lower. K. robustus is estimated to have had a body mass between 2802 and 7367 kg, making it generally larger than gomphotheres on account of its thicker limb bones. Its standing posture, however, was not likely as column-like as that of extant elephants and American brevirostrine gomphotheres.[4]
