Nasua

Nasua nasua (Linneaus 1766) is the extant coatimundi or coati. Here it nests close to Oxyaena andProcyon, the extant raccoon, but closer to Megistotherium. Nasua has three molars, all similar, and no carnasial tooth, distinct from all derived members of the Carnivora in the LRT (except Protictis, the anteating aardwolf)..
