Agathis trees of Patagonia's Cretaceous-Paleogene death landscapes and their evolutionary significance
(Botanical Society of America, 2018-08)
Premise of the Study: The fossil record of Agathis historically has been restricted to Australasia. Recently described fossils from the Eocene of Patagonian Argentina showed a broader distribution than found previously, ...

New age constraints for early Paleogene strata of central Patagonia, Argentina: Implications for the timing of South American Land Mammal Ages
(Geological Society of America, 2017-07)
The Río Chico Group in the San Jorge Basin of central Patagonia (Argentina) preserves some of South America’s most significant Paleogene records of biotic and climatic change. Three of its constituent formations, the Peñas ...
A Paleogene trans-Antarctic distribution for Ripogonum (Ripogonaceae: Liliales)?
(Coquina Press, 2014-03)
An impressive and growing list of biogeographically interesting plant and animal taxa occur in Paleogene sediments of both southern Australia and southern South America, indicating trans-Antarctic distributions during the ...
A new sebecid mesoeucrocodylian from the Paleocene of northwestern Argentina
(Taylor & Francis Ltd, 2021-10)
A new crocodyliform, Sebecus ayrampu, sp. nov., is described based on the rostral region of the skull, mandibular rami, and a distal portion of the femur collected in Paleocene rocks of northwestern Argentina. The new taxon ...
Diversity and biostratigraphy of the late Oligocene-late Miocene sand dollars (Echinoidea: Scutelliformes) of Argentina and Uruguay
(Universidad de Costa Rica, 2021)
New South American record of the Cretaceous–Paleogene boundary interval (La Colonia Formation, Patagonia, Argentina)
(Elsevier, 2021-10)
The La Colonia Formation is an Upper Cretaceous to Paleogene shallow marine sedimentary unit in Chubut Province (Patagonia), Argentina that preserves important vertebrate and plant fossils. Despite good exposures and ...
Controls on clay minerals assemblages in an early paleogene nonmarine succession: Implications for the volcanic and paleoclimatic record of extra-andean patagonia, Argentina
(Pergamon-Elsevier Science Ltd, 2014-02)
The distribution of the clay minerals of the Banco Negro Inferior-Río Chico Group succession (BNI-RC), a middle Danian–middle Eocene mainly continental epiclastic–pyroclastic succession exposed in the Golfo San Jorge Basin, ...
New age constraints for the Salamanca Formation and lower Río Chico Group in the western San Jorge Basin, Patagonia, Argentina: Implications for cretaceous-paleogene extinction recovery and land mammal age correlations
(Geological Society of America, 2014-01)
The Salamanca Formation of the San Jorge Basin (Patagonia, Argentina) preserves critical records of Southern Hemisphere Paleocene biotas, but its age remains poorly resolved, with estimates ranging from Late Cretaceous to ...
