Early eocene spore and pollen assemblages from the laguna del hunco fossil lake beds, patagonia, argentina
(University of Chicago Press, 2020-07)
Premise of research. The early Eocene Laguna del Hunco (LH) fossil site, northwestern Chubut Province, Argentina, holds one of the best-preserved and most diverse paleofloras worldwide. The paleoflora comprises ferns, ...
Insect Trace Fossil Associations in Paleosols: The Coprinisphaera Ichnofacies
(Society for Sedimentary Geology, 2000-02)
Analysis of fifty-eight paleosol trace fossil assemblages, ranging from the Triassic to the Recent, allows refinement of continental ichnofacies models and the proposal of a Coprinisphaera ichnofacies. The Coprinisphaera ...
First Fossil Assemblage of Darkling Beetles (Coleoptera: Tenebrionidae) from Buenos Aires, Argentina: Evidence of Dry Climate during the Late Pleistocene in the Humid Pampas
(Polish Academy of Sciences, 2016-12)
Late Pleistocene outcrops exposed in Buenos Aires province, Argentina, represent one of the most informative sources for paleoecological studies on South American fauna and flora. Several proxies have been used for studying ...
Depositional environment of Stelloglyphus Ilicoensis isp nov.: a new radial trace fossil from the Neogene Ranquil Formation, south-central Chile
(SERVICIO NACIONAL GEOLOGIA MINERVA, 2008-07)
Stelloglyphus llicoensis isp. nov. is a large radial, discoidal to ellipsoidal trace fossil with a central shaft and single to bifurcating branches radiating from different levels. A 30 m thick measured section of the ...
Salt marsh palynological assemblages as modern analogue tools for interpreting past vegetation zones and environmental conditions in the NE coastal plain of Argentina
(Pergamon-Elsevier Science Ltd, 2021-03)
In this study we examine the distribution patterns of modern palynological assemblages from different salt marsh zones and microenvironments in order to generate reference data for the north-central sector of Bahía Samborombo ...
Fossil beetles from pilauco, south-central chile: an upper pleistocene paleoenvironmental reconstruction
(2017)
A new assemblage of fossil beetles of Upper Pleistocene age, dated between 15,754 and 14,697 cal yr BP, is described and interpreted based on cluster analysis. In this study, we present an analysis on the taxonomic ...
Phytolith assemblages and systematic associations in grassland species of the south-eastern Pampean Plains, Argentina
(Oxford University Press, 2006-12)
• Background and Aims: Phytolith descriptions of South American plant species are scarce. This knowledge is crucial for the interpretation of the fossil phytolith record of a region. In this study phytolith assemblages and ...
Palaeonvironmental and palaeoecological significance of flamingo-like footprints in shallow-lacustrine rocks: An example from the Oligocene-Miocene Vinchina Formation, Argentina
(Elsevier Science, 2012-01)
This article describes the lacustrine trace-fossil assemblage of the Late Oligocene-Early Miocene Vinchina Formation of northwest Argentina. The thick (> 5000. m) continental succession of the formation is essentially ...
