“…Es frecuente en estudios previos de escelidoterinos (e.g. McDonald, 1987;Pujos, 2000;McDonald & Perea, 2002;Cartelle et al, 2009;, los dientes son denominados todos como molariformes, y por lo tanto para ellos la serie dentaria superior sería M1, M2, M3, M4 y M5 y la inferior, m1, m2, m3 y m4, creemos que la homología debe prevalecer como concepto fundamental previo a cualquier estudio fi logenético.…”

“…Según McDonald & Perea (2002) el género Scelidotherium está representado por dos especies, S. parodii y S. leptocephalum. Sin embargo, la situación de S. parodii es la siguiente; fue erigida por Kraglievich en 1923, sobre un cráneo parcialmente preservado (MACN 5108); tiempo después este mismo autor utilizó a este ejemplar como especie tipo para crear Scelidotheridium parodii Kraglievich, 1934(ver Pascual et al, 1966Aramayo, 1988).…”

“…De acuerdo a Gaudin (2004), los Scelidotheriinae conforman un grupo monofilético, caracterizado por presentar un cráneo alargado y estrecho, con una coincidente modificación de la serie dentaria y un astrágalo con una superficie cóncava para la articulación con el cuboides (Pascual et al, 1966;Scillato-Yané, 1977;McDonald & Perea, 2002;Miño-Boilini & Carlini, 2009), entre otros atributos anatómicos. Según McDonald & Perea (2002), esta subfamilia se encuentra constituida por seis géneros y su biocrón se extiende desde el Santacrusense (Mioceno medio) al Lujanense (Pleistoceno tardío-Holoceno temprano).…”

-ADDITIONS TO THE KNOWLEDGE OF PROSCELIDODON BORDAS, 1935 (MAMMALIA, XENARTHRA, SCELIDOTHERIINAE). The Scelidotheriinae subfamily constitutes a little diversified monophyletic group within the Mylodontidae, with a biochron that spans from the middle Miocene to the early Holocene. During the HuayquerianChapadmalalan age (late Miocene-middle Pliocene) the Scelidotheriinae are only represented by the genus Proscelidodon, being P. patrius the only species recognized for the Montehermosan stage/age (late Miocene-early Pliocene). Due to the scarcity of findings, the knowledge of the Neogene taxa included in this subfamily is limited, especially regarding the anatomical study of the postcranial skeleton. In this opportunity, the authors present the finding of a left hind limb partially complete in good condition of conservation, of an adult individual, assigned to Proscelidodon cf. P. patrius (Ameghino). The material was unearthed from the fluvial deposits of Monte Hermoso Formation (Buenos Aires, Argentina), in silty levels that represent flooding plain facies and that, biostratigraphically, correspond to Montehermosean stage/age. The detailed anatomical study of the different skeletal elements recovered, added to the comparison with other representative elements of this subfamily, provides novel data about the postcranial characteristics of Proscelidodon and allows us to evaluate its taxonomic and paleoecologic implications.Key words: Phyllophaga, Proscelidodon, Neogene, South America, anatomy, systematic.RESUMO -A subfamília Scelidotheriinae constitui um grupo monofilético pouco diversificado dentro dos Mylodontidae, com um intervalo de tempo que abarca desde o Mioceno médio até o Holoceno inferior. Durante o lapso HuayquerienseChapadmalalense (Mioceno tardio-Plioceno médio) os scelidoterinos estão representados somente pelo gênero Proscelidodon, sendo P. patrius a única espécie reconhecida para o piso/idade Montehermosense (Mioceno tardío-Plioceno inferior). Devido à escassez de registros, o conhecimento dos táxons neógenos incluídos nesta subfamília é limitado, principalmente no que se refere ao estudo anatômico do pós-crânio. O presente trabalho dá a conhecer um membro posterior esquerdo parcialmente completo e em bom estado de conservação, de um indivíduo adulto, atribuído a Proscelidodon cf. P. patrius (Ameghino). O material foi exumado de depósitos fluviais da Formação Monte Hermoso (Buenos Aires, Argentina), em horizontes limo-argilosos que representam fácies de planície de inundação e que, bioestratigraficamente, correspondem ao piso/idade Montehermosense. O estudo anatômico detalhado dos distintos elementos esqueléticos recuperados, somado a comparação com outros representantes desta subfamília, aporta dados inéditos sobre as características pós-cranianas de Proscelidodon e permite analisar suas implicações taxonômica e paleoecológica.

“…From a taxonomic perspective, the Scelidotheriinae, typified by Scelidotherium Owen, 1839, are the least diversified of the Mylodontidae and the only ones which, despite their wide geographic distribution in South America, had no involvement in the Great American Biotic Interchange (McDonald & Perea, 2002;Woodburne et al, 2006). Their representatives include middle-sized ground sloths characterized by an elongated and tubular skull, parallel dental series, laterally compressed teeth, flattened femur, and a concave cuboidal facet on the astragalus (e.g.…”

Gaudin (2004) indicated that the monophyly of this subfamily is supported by as many as 24 unambiguous synapomorphies, six of which are exclusive to the clade.…”

The subfamily Scelidotheriinae constitutes a group of mylodontids widely represented in the Quaternary of South America; however, the fossil record of the Neogene taxa is still scarce. In the present paper, a new specimen of this subfamily, corresponding to a right partial hemimandible with complete dental series, is reported. The material was recovered from the lower levels of the Arenisca Albardón Member of the Loma de Las Tapias Formation (San Juan Province, Argentina), assigned to the late Miocene. This finding represents the first record of a member of the Scelidotheriinae from the Chasicoan Stage/Age and provides new information about the anatomical characteristics and the geographic distribution of the Neogene representatives of this subfamily.
