Mammals From The Age Of Dinosaurs

Eomaia scansoria (holotype specimen, part and counterpart: Chinese Academy of Geological Sciences [CAGS] 01-IG-1A, 1B). The fossil comes from the Yixian Formation (125 Ma), Dawangzhangzhi locality, Lingyuan County, Liaoning Province, China. Called the "dawn mother," Eomaia scansoria, the earliest-known mammal more closely related to modern placentals than to modern marsupials, was the size of a shrew (ca. 14 cm long, estimated weight 20-30 g) and had several features in its manus and pes for adaptation to scansorial life.
