“…Following a recent revision (Krmpotic & Scillato-Yané, 2007 ), the species E. pascuali is known to occur only in the Ensenadan while E. seguini Gervais, 1867 is typically Lujanian (Krmpotic et al, 2009 ). A new species from the Lujanian was also recently described, E. crispianii Brambilla & Ibarra, 2017 , but this species shows foramina on the exposed surface larger than the hair foramina, which is not the case in our specimens. PIMUZ A/V 419 exhibits two pelvic shield osteoderms where the central figure is particularly large, with foramina on the exposed surface of a small size.…”

“…The same remark is valid concerning the lower teeth of PIMUZ A/V 418. All specimens of this section do not allow a precise determination as bony features of the distal limbs, mandible, and vertebrae are not diagnostic at the species level (Brambilla & Ibarra, 2017 ; Krmpotic et al, 2009 ). For this reason, I prefer to invalidate the initial assignment to E. seguini (Schulthess, 1920 ) and instead propose an open taxonomy by assigning these specimens to Eutatus sp.…”

The present work concerns xenarthrans from the collection of Santiago (Kaspar Jakob) Roth (1850–1924) housed at the Palaeontological Institute and Museum of the University of Zurich, one of the most important collections of Pleistocene mammals from Argentina in Europe. Roth was a paleontologist originally from Switzerland who prospected and collected a large amount of Pleistocene megafauna of the Pampean Region of Argentina. The xenarthrans are the main representatives of this collection in Zurich, with 150 specimens. Since 1920, this material has not been revised and is under studied. The present investigation corresponds to a taxonomic revision resulting in 114 reassignments, leading to document xenarthran diversity and discuss their paleoecologies. The high diversity reflects the paleoecology of the Pampean Region during the Pleistocene, with the various abiotic events that impacted the paleoenvironment of this region. Within the Cingulata, the Pampean Region fauna was probably dominated by glyptodonts with a high representation of Glyptodontinae and Neosclerocalyptinae while within the sloths the highest diversity and abundance is found in the Mylodontinae and Scelidotheriinae. These four clades represent both species with high ecological tolerance (e.g., Glyptodon munizi; Catonyx tarijensis) and ecologically highly specialized species (e.g., Neosclerocalyptus paskoensis; Scelidotherium leptocephalum). The presence of such ecological diversity underlines the status of the Pampean Region as a major interest for paleoecological and paleoenvironmental reconstruction.

Los vertebrados fósiles de las líneas costeras marinas a lo largo de la costa atlántica de la provincia de Buenos Aires, en el este de Argentina, son bien conocidos desde el siglo XIX. A pesar de ser frecuentes a lo largo de la costa del área de Cabo San Antonio, la descripción de los vertebrados e invertebrados fósiles encontrados a lo largo de la costa permanece casi sin documentar y su descripción ha sido mayormente anecdótica. El objetivo de la presente contribución es el de describir una gran colección de fósiles encontrados a lo largo de la playa de varias localidades en el área del cabo de San Antonio. Los fósiles incluyen una mezcla de animales terrestres y marinos que probablemente pertenecen a la Formación Pozo 10 (aproximadamente 120.000 años antes del presente), correlacionable con el evento transgresivo marino conocido como "Belgranense". Varios fósiles sugieren aguas cálidas, reminiscentes de las que ocurren hoy en día en el norte de Brasil. Los fósiles aquí reportados son muy similares a los de los conjuntos de fósiles costeros encontrados en el sur de Brasil, Uruguay y el sur de la provincia de Buenos Aires, lo que sugiere algún tipo de continuidad faunística y ambiental a lo largo de las costas del sur durante el Pleistoceno medio.
