Nanocuris

Nanocuris is an extinct genus of Deltatheridiidae from the Cretaceous of Canada (Saskatchewan) and United States (Wyoming - Lance Formation and Hell Creek Formation^[1]).^[2] Initially, it was classified in a proper family, Nanocuridae, in the clade Eutheria,^[2] but a reanalysis of a new specimen revealed a delthatheroid affinity of the genus.^[3]

Size

It was the largest deltatheroidean.^[4][5] Alongside with the similarly sized Altacreodus, it likely replaced earlier Cretaceous eutriconodonts as a large sized predatory mammal.^[6]

Its closest relative is the smallest deltatheroidean, Gurbanodelta.^[7]
