Neotherium mirum is an extinct species of basal walrus. It was smaller than living forms and it did not have long tusks. Males were larger than females.

Palaeoecology

Stable isotope evidence indicates that in the eastern North Pacific, Neotherium had intermediate foraging habits between the nearshore specialist Pithanotaria and the offshore specialist Allodesmus.
