Resumen:
ABSTRACT—A new form of Xenungulata Paula Couto, 1952 from red levels of the Pen˜as Coloradas Formation in a locality near Puerto Visser (4517S, 6701W), Chubut province, Argentina, is represented by a fragmentary left jaw with the m3 (MPEF-PV 1871). Notoetayoa gargantuai (4517S, 6701W), Chubut province, Argentina, is represented by a fragmentary left jaw with the m3 (MPEF-PV 1871). Notoetayoa gargantuai BSTRACT—A new form of Xenungulata Paula Couto, 1952 from red levels of the Pen˜as Coloradas Formation in a locality near Puerto Visser (4517S, 6701W), Chubut province, Argentina, is represented by a fragmentary left jaw with the m3 (MPEF-PV 1871). Notoetayoa gargantuai17S, 6701W), Chubut province, Argentina, is represented by a fragmentary left jaw with the m3 (MPEF-PV 1871). Notoetayoa gargantuai n. gen. and n. sp. is the first ever found in direct association with Carodnia feruglioi Simpson, 1935a which characterizes the incompletely known homonymous zone of the late Paleocene of Patagonia. A preliminary phylogenetic analysis, including representatives of ‘‘Condylarthra’’, Litopterna, Notoungulata, Pyrotheria, Xenungulata and Astrapotheria, plus the characters that could be scored in the new taxon, was performed using TNT software. A single most parsimonious tree was obtained. Notoetayoa gargantuai has a closer phylogenetic relationship with the Xenungulata Etayoa bacatensis Villarroel, 1987 from the ?middle Paleocene of Colombia than with any other Tertiary ungulate group of South America. Notoetayoa gargantuai fills an important gap in the knowledge of the mammalian faunas from the Paleocene of Patagonia, particularly of the poorly known pre-Itaborian times. of the poorly known pre-Itaborian times.
