It was the size of a modern leopard, weighing about 165 kg (365 lb) and wielding retractable claws (convergent with the condition found in cats) and a thumb that could help it climb and grasp prey.

Pilosa Xenarthra primitive than the insectivorous mammals that make up most of our Late Cretaceous record of placentals.
