Eubelodon is an extinct genus of gomphothere (a family in the order Proboscidea, which also includes modern elephants) which lived in North America during the Miocene Epoch. It contains a single species: Eubelodon morrilli.
Eubelodon is considered to be a trilophodont gomphothere. It has the highly unusual combination of retaining a long lower jaw, but having lost the lower tusks, a combination only shared with fellow North American gomphothere Gnathabelodon and the choerolophodontidChoerolophodon.[1]
Eubelodon was named by Erwin Hinckly Barbour in 1914. It was synonymized subjectively with Trilophodon by Osborn in 1918 and again by Tobien in 1973 with Gomphotherium.[3]
It was assigned to Gomphotheriidae by Erwin Barbour in 1914. It was then assigned to Rhynchotheriinae by McKenna and Bell in 1997,[4] Carroll in 1988, Shoshani and Tassy in 1996, Lambert and Shoshani in 1998, and Shoshani and Tassy in 2005.
