“…These data have been complemented with recent fieldwork and further studies in the northern part of the continent (e.g. Kay et al 1997;Cozzuol 2006;Croft 2007;Latrubesse et al 2010;Sánchez Villagra et al 2010) and mostly in Neogene strata. Distinct from both of these areas, Mendoza province, western Argentina, is just north of Patagonia and was the source of the extremely specialized marsupial Groeberia minoprioi (Polydolopimorphia, Argyrolagoidea).…”

The only known specimen is a juvenile with fragments of both dentaries, the right maxilla and a fragment of the left premaxilla with dentition. The loci and the number teeth preserved suggest a dental formula of I?3/i3, C1/c1, P3/p3, M?3/m?3. Fieratherium sorex has a convergent shrew-like appearance and a unique combination of features among metatherians and other South American mammals of Palaeogene age, including the well-known faunas of Patagonia. An analysis of its phylogenetic affinities suggests that Fieratherium is the sister-group of the Paucituberculata. As already described by other authors for several mammalian taxa, the mainly Patagonian South American Palaeogene fossil record offers little information to understanding the evolution of northern lineages. Fieratherium may represent a taxon belonging to a lineage that had its origin in Neotropical regions, so far unrecorded in the southern region of South America.http://zoobank.org/urn:lsid:zoobank.org:pub:5F6D3A50-6345-4E66-BE3E-7FEF6CC66A9B

It is important to note that Huayquerian age assignments have frequently been made for Neotropical mammal associations recovered from a wide variety of other contexts throughout South America, such as Urumaco in Venezuela (Linares, 2004) and Acre in Brazil (Cozzuol, 2006;Ribeiro et al, 2013). This also applies to the correlation of presumed age-equivalent stratigraphic units, such as the Cerro Azul and Epecuén Formations in the Pampean area (Goin et al, 2000;Montalvo et al, 2008;Verzi et al, 2011), the Chiquimil or Andalhuala formations in northwestern Argentina (e.g., Reguero and Candela, 2011; see also Esteban et al, 2014, for a discussion on the topic and references herein cited).…”

The development of the transcontinental Amazon River System involved geological events in the Andes Chain; Vaupés, Purus and Gurupá arches; sedimentary basins of the region and sea level changes. The origin and age of this river have been discussed for decades, and many ideas have been proposed, including those pertaining to it having originated in the Holocene, Pleistocene, Pliocene, Late Miocene, or even earlier times. Under this context, the geology of the sedimentary basins of northern Brazil has been analyzed from the Mesozoic time on, and some clarifications are placed on its stratigraphy. Vaupés Arch, in Colombia, was uplifted together with the Andean Mountains in the Middle Miocene time. In the Cenozoic Era, the Purus Arch has not blocked this drainage system westward to marine basins of Western South America or eastward to the Atlantic Ocean. Also the Gurupá Arch remained high up to the end of Middle Miocene, directing this drainage system westward. With the late subsidence and breaching of the Gurupá Arch and a major fall in sea level, at the beginning of the Late Miocene, the Amazon River quickly opened its pathway to the west, from the Marajó Basin, through deep headward erosion, capturing a vast drainage network from cratonic and Andean areas, which had previously been diverted towards the Caribbean Sea. During this time, the large siliciclastic influx to the Amazon Mouth (Foz do Amazonas) Basin and its fan increased, due to erosion of large tracts of South America, linking the Amazon drainage network to that of the Marajó Basin. This extensive exposure originated the Late Miocene (Tortonian) unconformity, which marks the onset of the transcontinental Amazon River flowing into the Atlantic Ocean.
