Cretaceous-Paleogene plant extinction and recovery in Patagonia
(Cambridge University Press, 2020-10)
The Cretaceous-Paleogene (K/Pg) extinction appears to have been geographically heterogeneous for some organismal groups. Southern Hemisphere K/Pg palynological records have shown lower extinction and faster recovery than ...
The youngest South American rhynchocephalian, a survivor of the K/Pg extinction
(The Royal Society, 2014-08)
Rhynchocephalian lepidosaurs, though once widespread worldwide, are represented today only by the tuatara (Sphenodon) of New Zealand. After their apparent early Cretaceous extinction in Laurasia, they survived in southern ...
Rapid recovery of Patagonian plant–insect associations after the end-Cretaceous extinction
(Springer Nature, 2016-11)
The Southern Hemisphere may have provided biodiversity refugia after the Cretaceous/Palaeogene (K/Pg) mass extinction. However, few extinction and recovery studies have been conducted in the terrestrial realm using well-dated ...
The upper Maastrichtian dinosaur fossil record from the southern Pyrenees and its contribution to the topic of the Cretaceous–Palaeogene mass extinction event
(Academic Press Ltd - Elsevier Science Ltd, 2016-01)
In the present paper, the fossil record of the archosaurs (dinosaurs, crocodylomorphs and pterosaurs) of the southern Pyrenees before the Cretaceous–Palaeogene (K–Pg) transition is revised. On the basis of this fossil ...
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 ...
Extinction at the end-Cretaceous and the origin of modern Neotropical rainforests
(American Association for the Advancement of Science, 2021-04)
The end-Cretaceous event was catastrophic for terrestrial communities worldwide, yet its long-lasting effect on tropical forests remains largely unknown. We quantified plant extinction and ecological change in tropical ...
Changes in the Diversity of Turtles (Testudinata) in South America from the Late Triassic to the PresentCambios en la diversidad de tortugas (Testudinata) en América del Sur desde el triásico tardío hasta el presente
(Asociación Paleontológica Argentina, 2018-12)
Los avances recientes en el registro fósil, la anatomía y la historia evolutiva de las tortugas sudamericanas permiten un análisis exhaustivo de sus cambios en la diversidad y la identificación de eventos importantes de ...
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 ...
