The type species, Microbunodon minimum, lived in the Oligocene in Europe and is known in France, Germany, Switzerland, Austria and Turkey.

Other species attributed to this genus are M. silistrensis (early and middle Miocene, Indian subcontinent and Indochina) and M. milaensis (late Miocene and early Pliocene, Indian subcontinent and Indochina).

Other fossils attributed to this genus come from the upper Eocene of China and testify to an exceptional longevity of this evolutionary line.

Microbunodon represents an aberrant morphology for this family, whose members usually have large, heavy shapes.

[4] Analysis of dental wear of Microbunodon reveals that it probably had a diet based on leaves and fruit.
