Conifer woods from the Salamanca Formation (early Paleocene), Central Patagonia, Argentina: Paleoenvironmental implications
(Pergamon-Elsevier Science Ltd, 2017-07)
The main objective of the present work is to describe the first conifer assemblage of a mixed forest from the Danian Salamanca Formation at the Estancia Las Violetas locality (San Jorge Basin, Central Patagonia, Argentina), ...
Early foreland deformation of the Fuegian Andes (Argentina): Constraints from the strain analysis of Upper Cretaceous-Danian sedimentary rocks
(Elsevier, 2013-01)
This contribution addresses new structural data from Upper Cretaceous-Danian sedimentary rocks of the Fuegian Andes orogenic front in Argentina. The structures studied, called D0 , were formed during the early foreland ...
Fossil flowers from the early Palaeocene of Patagonia, Argentina, with affinity to Schizomerieae (Cunoniaceae)
(NLM (Medline), 2018-03-04)
Background and Aims: Early Palaeocene (Danian) plant fossils from Patagonia provide information on the recovery from the end-Cretaceous extinction and Cenozoic floristic change in South America. Actinomorphic flowers with ...
Before and after the K/Pg extinction in West Antarctica: New marine fish records from Marambio (Seymour) Island
(Academic Press Ltd - Elsevier Science Ltd, 2018-05)
An ichthyofauna recovered from the López de Bertodano Formation at Units 9 (uppermost Maastrichtian) and 10 (lowermost Danian) and the Sobral Formation (Danian), in Marambio (Seymour) Island in the James Ross Basin is ...
Maastrichtian to Danian Atlantic transgression in the north of Patagonia: A dinoflagellate cyst approach
(Pergamon-Elsevier Science Ltd, 2019-06)
The late Maastrichtian to early Paleocene marine successions in northern Patagonia and neighboring southwestern Atlantic Ocean Basins provided a valuable organic-walled dinoflagellate cysts record. Assemblages around the ...
Gastropods associated with Fossil Traces from Yacoraite Formation(Maastrichtian-Danian), and its Paleoenvironmental Significance, Jujuy, Northwestern Argentina
(Wiley Blackwell Publishing, Inc, 2009-10)
We present results tending to characterize the new records of invertebrates from the Yacoraite Formation (Maastrichtian-Danian). The fossils reported come from two stratigraphic sections exposed in the surroundings of ...
A new cycad trunk from the Palaeocene in the Neuquén Basin, Patagonia (Argentina)
(Elsevier Science, 2018-09)
To date only two genera of cycad stems have been described from Cenozoic strata (Bororoa and Menucoa). We describe a new species of Wintucycas, Wintucycas beatrizae sp. nov. (Encephalartoideae), from the basal Palaeogene ...
Paleoenvironmental interpretation of the Danian-Selandian transition (Paleocene) in the North Sea Basin based on foraminifera
(Centro de Ciências Matemáticas e da Natureza, Instituto de Geociências, Universidade Feder, 2006)
The Maastrichtian–Danian Maimará tracksite (Yacoraite Formation, Salta Group), Quebrada de Humahuaca, Argentina: environments and ichnofacies implications
(Elsevier Science, 2017-02)
The shoreline carbonate lagoon deposits of the Yacoraite Formation in the Maimará locality, Quebrada de Humahuaca (Jujuy, northwestern Argentina) reveal invertebrate and vertebrate trace fossils that are distributed in two ...
Flowering after disaster: Early Danian buckthorn (Rhamnaceae)
(Public Library of Science, 2017-05-10)
Southern-Hemisphere terrestrial communities from the early Paleocene are poorly known, but recent work on Danian plant fossils from the Salamanca Formation in Chubut Province, Argentina are providing critical data on ...
