As a gompothere elephant, Gnathabelodon differed from today’s elephants by having enlarged incisor teeth in the lower jaw that formed a ‘shovel’ protruding from the tip of the lower jaw. In the past Gnathabelodon has been considered to be the same elephant as the closely related Gompotherium (the type genus of the Gomphotheriidae), though today Gnathabelodon is still usually treated as a distinct genus.
