A stem anseriform from the early Palaeocene of Antarctica provides new key evidence in the early evolution of waterfowl
(Wiley Blackwell Publishing, Inc, 2019-07)
A new Anseriformes, Conflicto antarcticus gen. et sp. nov., represented by associated bones of a single individual, from the early Palaeocene of Antarctica is described. The new taxon is unlike any other known member of ...
First argiolestid damselfly (Odonata: Zygoptera) from the late Palaeocene of Northwest Argentina
(Magnolia Press, 2020-12)
Megapodagrionids in the wide sense are a polyphyletic group of damselflies (Huang et al., 2018). In recent studies there is a tendency to restrict the Megapodagrionidae only to few genera, and to over rank some subfamilies ...
A new Palaeocene crocodylian from southern Argentina sheds light on the early history of caimanines
(The Royal Society, 2018-08)
Caimanines are crocodylians currently restricted to South and Central America and the oldest members are from lower Palaeocene localities of the Salamanca Formation (Chubut Province, Argentina). We report here a new caimanine ...
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 ...
Unravelling the widening of the earliest Andean northern orogen: Maastrichtian to early Eocene intra-basinal deformation in the northern Eastern Cordillera of Colombia
(Wiley-Blackwell Publishing Ltd, 2020-07-21)
The onset of deformation in the northern Andes is overprinted by subsequent stages of basin deformation, complicating the examination of competing models illustrating potential location of earliest synorogenic basins and ...
An integrated stratigraphic record of the Palaeocene-lower Eocene at Gubbio (Italy): new insights into the early Palaeogene hyperthermals and carbon isotope excursions
(WILEY-BLACKWELLHOBOKEN, 2012)
Terra Nova, 24, 380386, 2012 Abstract A high-resolution, integrated stratigraphic framework (stable isotope stratigraphy, standard calcareous nannofossil and foraminiferal biostratigraphy, magnetostratigraphy) together ...
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 ...
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 ...
A new sebecid mesoeucrocodylian from the Rio Loro Formation (Palaeocene) of north-western Argentina
(Wiley Blackwell Publishing, Inc, 2011-12)
A new basal mesoeucrocodylian, Lorosuchus nodosusgen. et sp. nov., from the Palaeocene of north-western Argentina is presented here. The new taxon is diagnosed by the presence of external nares facing dorsally, completely ...
New evidence from the Palaeocene of Patagonia (Argentina) on the evolution and palaeobiogeography of Meiolaniformes (Testudinata, new taxon name)
(Taylor & Francis, 2013-12-12)
Peligrochelys walshae gen. et sp. nov. is a new stem turtle closely related to the clade Meiolaniidae found in the Palaeocene levels of the Salamanca Formation (Maastrichtian?Danian) of central Patagonia, Chubut Province, ...
