Neoreomys is an extinct genus of caviomorph rodent that lived in South America during the Miocene epoch.[1]
Taxonomy
Phylogenetic analysis has shown Neoreomys to be a monophyletic genus not closely related to Dasyproctidae, but instead representing a plesiomorphic member of Cavioidea.[2]
Palaeobiology
Locomotion
Geometric morphometric analysis of the foot of Neoreomys points to it having had a generalised mode of ambulation, in contrast to other Late Oligocene and Early Miocene caviomorphs.[3]
Palaeoecology
Dental microwear analysis has found that Neoreomys australis was a consumer of fruits and seeds.[4]
