Paramys

Paramys is an extinct genus of rodents from North America, Europe, and Asia. It is one of the oldest genera of rodents known and probably lived in trees. While the genus name literally means "near a mouse", it coexisted with Thisbemys, a similar rodent, thus yielding a reference to Pyramus and Thisbe.

== Description == The brain of both the Early Eocene P. copei and the Middle Eocene P. delicatus was characterised by a lower neocortical surface area, smaller paraflocculi, and larger olfactory bulbs relative to total endocranial volume of later rodents, and they both possessed encephalisation quotients higher than that of Ischyromys typus.
