The fossils were recovered from the [[Lagerstätten|lagerstätte]] of the [[Yixian Formation]] in the Liaoning province of China, which is renowned for its extraordinarily well-preserved fossils of [[feathered dinosaurs]]. They have been specifically dated to 125–123.2 [[million years ago]], during the [[Early Cretaceous]] period.

''Repenomamus'' is a [[genus]] of [[eutriconodont]]s, a group of early [[mammal]]s with no modern relatives. ''R. robustus'' was described by Li, Wang, Wang and Li in 2001, and ''R. giganticus'' was described by Hu, Meng, Wang and Li in 2005. The two known [[species]] are the sole members of the family Repenomamidae, which was also described in the same paper in 2001. It is sometimes alternatively listed as a member of the family [[Gobiconodontidae]]; although this assignment is controversial, a close relationship to this family is well-founded.
