Adapisoriculidae is a family of primitive small mammals known from India, Europe and Northern Africa ranging in age from Late Cretaceous to early Eocene. The 2019 sample of limestone from Black Crow, Namibia, yielded an upper molar which is interpreted to belong to this enigmatic family, thereby greatly extending the geographic range of the group. The specimen is described and illustrated but is left in open nomenclature, pending recovery of more complete remains. Keywords: Adapisoriculidae, Ypresian/Lutetian, Upper molar, Namibia.
