Abstract	Los gliptodontes (Glyptodontidae, Xenarthra) fueron elementos muy frecuentes entre los megaherbivoros del Cenozoico de America del Sur (Paula Couto, 1979; Zurita et al., 2010). Durante el Plioceno tardio y Pleistoceno tuvieron una amplisima distribucion latitudinal en America del Sur; se los encuentra desde la Argentina hasta Venezuela (Carlini & Zurita, 2010). Entre los gliptodontes del Cenozoico Superior, solo Doedicurus Burmeister, 1874, Neosclerocalyptus Paula Couto, 1954 y Glyptodon Owen, 1839 se registran durante el Holoceno (Politis & Gutierrez, 1998; Gutierrez et al., 2010; Cione et al., 2009). Todos los gliptodontes, junto a otros 43 generos de megamamiferos y grandes mamiferos, se extinguieron en America del Sur entre fines del Pleistoceno y comienzos del Holoceno (Cione et al., 2009). Recientemente ABSTRACT – A LARGE GLYPTODONTIDAE IN THE EARLY HOLOCENE OF THE PAMPEAN REGION, ARGENTINA. We present here the record of a very large glyptodont (1,900 to 2,370 kg); it is a right humerous distal epiphysis (RPCR 1021) coming from the early Holocene (8,480 ± 130 years 14C cal. BP) of the Pampean Region (Los Pozos, Marcos Paz, Buenos Aires Province, Argentina) and we assign it to Doedicurus Burmeister cf. D. Clavicaudatus (Owen). The youngest record for a glyptodont (7,839 ±102 years 14C cal. BP) corresponds to Doedicurus clavicaudatus. Finally we discuss the possible explanations of the great size attained by glyptodonts at the end of the Lujanian age (late Pleistocene-early Holocene).
