Deltatheridiidae
Extinct family of mammals / From Wikipedia, the free encyclopedia
Not to be confused with Deltatheriidae.
Deltatheridiidae is an extinct family of basal carnivorous metatherians that lived during the Cretaceous and Paleogene. They were closely related to marsupials. Their fossils are restricted to Central Asia (Mongolia and Uzbekistan) and North America (United States - Oklahoma, Texas, Utah, Wyoming). They mostly disappeared in the KT event, but a ghost lineage, currently represented by Gurbanodelta, survived until the late Paleocene by decreasing in size and becoming insectivorous.[1]
