Eomyidae is a scarcely known family of extinct rodents. The natural history of the family is practically based solely on dental, mandibular and limited cranial remains. However, Eomyodon volkeri is one of the very rare specimens with postcranial material preserved.
The authors that described the specimen (Engler & Martin 2015) state that, based on several limb indices, and no gliding membrane present (as opposed to the closely related, gliding Eomys), it was a terrestrial, ground-dwelling form with a rather generalized proportions for a rodent. The estimated weight is around 10 g. While the preserved specimen indicates considerable fur coverage, the individual hairs and stomach content remains unidentifiable. It lived in the swamp and mesophytic forests in the vicinity of a large, isolated maar lake with an anoxic bottom, which with numerous other fauna enabled the exceptional state of preservation. It lived during the Late Oligocene (MP28, ~24Ma), in present day Germany.
