Neotamandua is an extinct genus of anteaters that lived in the Miocene to Pliocene in South America. Their fossils have been found in the Miocene Collón Curá Formation of Argentina,[2] the Honda Group at La Venta in Colombia and the Pliocene Araucano Formation in Argentina.[3] Its closest living relatives are the giant anteater (Myrmecophaga tridactyla) and tamanduas (genus Tamandua).[3][2] The species Neotamandua borealis was suggested to be an ancestor of the giant anteater.[4] Patterson (1992) suggested the Neotamandua fossils are very similar to Myrmecophaga, which would mean Neotamandua may be congeneric with Myrmecophaga.[2]
