“…Conglomerates above the unconformity often contain the Huayquerian mammal fossil fauna (SALMA -South American Land Mammals Age) and other fossil groups, indicating Late Miocene age between 9 and 6.5 Ma for fauna and sediments associated with the lower Solimões Formation, which unit was well detailed by Latrubesse et al (2007Latrubesse et al ( , 2010 and Gross et al (2011).…”

“…Russel datings were presented in a table by Abinader (2008, p. 15) It is interesting to note that ages of zircon minerals from Central Amazonia and Ventuari-Tapajós provinces, which now occupy over 50% of the area traversed by the Amazon River, were not found in the earliest Late Miocene sediments of Foz do Amazonas Basin. Latrubesse et al (2010) raised this inquiry to the model presented by Figueiredo et al (2009). On the other hand, the rather abundant presence of zircon minerals dated as Brasiliano in the earliest Late Miocene sediments of Foz do Amazonas Basin (personal communication from Jorge de Jesus Picanço de Figueiredo 2015) indicates a source different from the one of the cratonic areas crossed by the Amazon River, keeping in mind that the ancestral Amazon River drainage flowed westward up to the earliest Late Miocene.…”

Bezerra (2003), Rossetti et al (2005) and Bezerra and Ribeiro (2015) inferred the Amazon River to have flowed through the Tacutu Rift, the Essequibo River and the coast of Guyana Republic to the Atlantic Ocean in the Plio-Pleistocene and at the end of the Pleistocene and in the Holocene, being guided to its present valley site, by following neotectonic faults.…”

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.

“…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

A multidisciplinary approach is used to analyze the Cenozoic uplift history of South America. Residual depth anomalies of oceanic crust abutting this continent help to determine the pattern of present‐day dynamic topography. Admittance analysis and crustal thickness measurements indicate that the elastic thickness of the Borborema and Altiplano regions is ≤10 km with evidence for sub‐plate support at longer wavelengths. A drainage inventory of 1827 river profiles is assembled and used to investigate landscape development. Linear inverse modeling enables river profiles to be fitted as a function of the spatial and temporal history of regional uplift. Erosional parameters are calibrated using observations from the Borborema Plateau and tested against continent‐wide stratigraphic and thermochronologic constraints. Our results predict that two phases of regional uplift of the Altiplano plateau occurred in Neogene times. Regional uplift of the southern Patagonian Andes also appears to have occurred in Early Miocene times. The consistency between observed and predicted histories for the Borborema, Altiplano, and Patagonian plateaux implies that drainage networks record coherent signals that are amenable to simple modeling strategies. Finally, the predicted pattern of incision across the Amazon catchment constrains solid sedimentary flux at the Foz do Amazonas. Observed and calculated flux estimates match, suggesting that erosion and deposition were triggered by regional Andean uplift during Miocene times.
