Didymoconidae

__TOC__

Didymoconidae is an extinct family of eutherian mammals of unknown affinities, they ranged from the early Paleocene to late Oligocene and were endemic to Asia. Like a majority of early Cenozoic mammal groups, the exact taxonomic placement of didymoconids is poorly understood but a few groups do consistently come up. The most common suggestion is one that has been brought up since their original description, that being their close relationship to Mesonychidae. Though not agreed upon by a number of authors, this does appear in the most recent phylogeny containing the two groups. Other suggestions of close relatives include Zalambdalestidae, Macroscelidea, Lagomorpha, and the now obsolete order Insectivora.
