Rhynchotherium
Rhynchotherium is an extinctgenus of gomphothereendemic to the southern USA and Mexico from the Miocene to the Early Pleistocene (5.9 to 2.2 Ma). This temporal range also corresponds from the late Hemphillian faunal stage (Hh4) to the Late Blancan faunal stage, with Rhynchotherium being considered by some researchers as a taxon emblematic of the Blancan faunal stage. Rhynchotherium had two tusks and likely evolved from Gomphotherium.
