How did the Gomphotherium go extinct?
They had lost the enamel on their upper tusks, lost or severely reduced their lower tusks (Mothe et al., 2016) and had mixed browsing but also grazing diets (Pérez-Crespo et al., 2016). These genera went extinct rather recently in the Holocene, during the Ice Ages 12,000 to 10,000 years ago.
