Sharamynodon fossil map
Where fossils of Sharamynodon have been found, shown on the Earth as it looked about 45 million years ago and on today’s map.
Dots are fossil collections recorded in the Paleobiology Database. The “then” view moves today’s fossil sites back to their positions 45 million years ago (the time slice nearest the median age of the fossils) using the Merdith et al. (2021) plate model; positions are approximate. Open on the timeline map →

About Sharamynodon
Sharamynodon ("Shara [Murun] Amynodon") is an extinct genus of amynodont that lived in Central and East Asia during the Middle to Late Eocene, in the Irdinmanhan and Sharamurunian land mammal ages. The type species, S. mongoliensis, is known from fossils found in Kazakhstan and Inner Mongolia, China. S. mongoliensis stood about 1.4 meters (4.6 ft) tall at the withers and weighed about a tonne (1.1 short tonnes). Alongside contemporary brontotheres, it was one of the largest Asian ungulates of its time.
Sharamynodon was a relatively unspecialized amynodont, and was closely related to the contemporary North American genus Amynodon. Both the diversity and temporal range of Sharamynodon are disputed. A large number of amynodont species have been named based on fragmentary fossils from East Asia; several of these have been argued to possibly represent fossils of Sharamynodon, and additional species of the genus are sometimes recognized. The genus Lushiamynodon, known from China and Kyrgyzstan, has also been argued to possibly be a junior synonym of Sharamynodon.
