ABSTRACT We describe a partial braincase of the basal sauropodomorph Panphagia protos from Upper Triassic (mid-Carnian) horizons Ischigualasto Formation. The disarticulated subadult individual includes one frontal, both parietals, prootic, and supraoccipital. frontal is longer anteroposteriorly than it wide transversely, has small anterolateral process, an elongate oval depression for olfactory bulb. supraoccipital broader transversely deep dorsoventrally lacks pronounced median nuchal...
The first nearly complete and articulated manus of the ground sloth Mylodon darwinii, from upper Pleistocene Argentina, is described. It shares similarities with Mylodonopsis ibseni Brazil, including a cuneiform distinct pisiform facet, an obliquely concave ulnar prominent distolateral process, as well gracile metacarpal III. flattened Glossotherium robustum. trapezoid unique in elongate proportions its dorsal surface. Shapes articular facets indicate different functions digits II III,...
ABSTRACT Here, we present information regarding the braincase anatomy of Chanaresuchus ischigualastensis, from Ischigualasto Formation (Carnian) Argentina. The is very similar to that previously described for bonapartei, but bears some differences: rostral contour basal tubera nearly transversely oriented in ventral view; with rounded distal tips paroccipital processes a slight widening caudal sulcus on surface each process restricted proximal two-thirds latter; and parabasisphenoidal...
In this work, we describe postcranial elements of Mylodon listai distributed in collections from Argentina, Chile and Europe. remains Patagonia are clearly different those the Pampean region (Mylodon darwinii), presenting morphological differences their postcranium such as a smaller intercondylar space less displacement medial condyle femur. These anatomical features reveal that M. had bowed legs than darwinii. We propose would be an adaptation to fossorial lifestyle habitats southern...
Here, we report new autopodial material belonging to a scelidotheriine sloth from the Pliocene (Chapadmalalan) of Rio de La Cruz valley, Córdoba province, Argentina. The epiphyseal suture fusion in metacarpals III and IV indicates adult size; compared with other scelidotheriines, preserved bones are slightly larger than pre-Chapadmalalan taxa, but quite smaller post-Chapadmalalan taxa. metacarpal presents distal carina longer relative proximodistal length – proximalmost point proximal end...
New fossil remains were found in Neogene and quaternary sedimentary sequences exposed Alpa Corral río San Bartolomé localities (Rio Cuarto Department, Córdoba, Argentina). They assigned to Nopachtus cabrerai (Xenarthra, Cingulata, Glyptodontidae), Notiomastodon platensis (Proboscidea, Gomphotheriidae) cf. Trigodon gaudryi (Notoungulata, Toxodontidae), traces of the Scoyenia ichnofacies, as Taenidium barretti, identified. Based on these findings, we conclude that: 1, species are registered...
