Nanocuris

Description

Nanocuris is an extinct genus of Deltatheridiidae from Cretaceous of Canada (Saskatchewan) and United States (Wyoming - Lance Formation). Initially was classified in a proper family, Nanocuridae, in clade Eutheria, but a reanalysis of a new specimen reveal a deltharoid affinity of the genus.
