Microchoeridae

Family of omomyoids known from the middle Eocene to the early Oligocene of Europe; four genera and twenty species; well known from many specimens. This group may be descended from an early member of the Anaptomorphinae. Orbits are large, suggesting nocturnality; postorbital wall only partly closed; short snout. Great variation in body mass between the genera, ranging from 50 g to 2 kg. Dental formula variable, although maxillary dentition is 2.1.3.3/2.1.3.3; dental morphology suggests diversity of diet among the different genera. Postcrania indicate leaping abilities.
