A LARGE GLYPTODONTIDAE IN THE EARLY HOLOCENE OF THE PAMPEAN REGION, ARGENTINA. We present here the record of a very large glyptodont (1,900 a 2,370 kg); it is a right humerous distal epiphysis (RPCR 1021) coming from the early Holocene (8,480 ± 130 years 14 C 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 14 C 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).
