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 ...
The fossil record of Ceratophrys Wied-Neuwied (Anura: Ceratophryidae): A revision and update of fossil South American horned frogs
(Magnolia Press, 2019-08)
Ceratophrys is the most diverse and widely distributed genus of Ceratophryidae, the clade of South American horned frogs. Numerous anuran fossil remains, including several fossil species, have been assigned to this genus. ...
Fossil groups in the Millennium simulation: From the brightest to the faintest galaxies during the past 8 Gyr
(EDP Sciences, 2016-02)
Aims. We investigate the evolution of bright and faint galaxies in fossil and non-fossil groups. Methods. We used mock galaxies constructed based on the Millennium run simulation II. We identified fossil groups at redshift ...
The micro-and megafossil record of Nothofagaceae from South America
(Wiley Blackwell Publishing, Inc, 2020-12)
We compiled the numerous fossil records (486) assigned to Nothofagaceae including pollen grains (from surface sediments and continental and oceanic borehole cores), leaves, woods and reproductive structures from South ...
Beyond Coprinisphaera: fossil nests of dung beetles
(Wiley Blackwell Publishing, Inc, 2018-01)
Forty-two remains of fossil nests of dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae), which were recorded in four formations of the Cenozoic of South America, are described herein for the first time. Most of them are ...
Fossil pollen records reveal a late rise of open-habitat ecosystems in Patagonia
(Nature Publishing Group, 2012-12)
The timing of major turnovers in terrestrial ecosystems of the Cenozoic Era has been largely interpreted from the analysis of the assumed feeding preference of extinct mammals. For example, the expansion of open-habitat ...
