THE CINGULATA (MAMMALIA, XENARTHRA) FROM THE CONGLOMERADO OSÍFERO (LATE MIOCENE) OF THE ITUZAINGÓ FORMATION OF ENTRE RÍOS PROVINCE, ARGENTINA. The Cingulata from the Conglomerado osífero (late Miocene) of the Ituzaingó Formation include three families: Dasypodidae, Pampatheriidae, and Glyptodontidae (plus a Peltephilidae mentioned by Ameghino in 1906). Most of the species were recognized and described by Ameghino between 1883 and 1886. Most of the paleontological specimens are allochthonous and articulated-findings specimens are exceptional, except for skulls and partial dorsal carapaces. In addition, several types of the species recognized by Ameghino are lost and there are only a few calcotypes (approximately 50% of the species of Glyptodontidae). Thus, this taxonomic update is in part, preliminar, and more complete specimens are necessary to test the validity of the recognized taxa. In this context, we recognized five species of Dasypodidae, two of Pampatheriidae and thirteen of Glyptodontidae. In the Conglomerado osífero, each genus of Cingulata has only one species. All the Cingulata of the Conglomerado osífero? were approximately contemporary although not necessarily occupying the same environments. Assuming a model of gallery forest of one (or more) lotic courses, the smaller Cingulata could have used the forests, whereas the larger ones could have occupied the savannas stretching outwards from the galleries.
