An assemblage of large-sized insect traces in paleosols from the middle miocene of northern Patagonia related to the climatic optimum
(Pergamon-Elsevier Science Ltd, 2021-08)
A new assemblage of large insect trace fossils is recognized in paleosols of the middle Miocene pyroclastic deposits from extra-Andean north Patagonia. This assemblage includes Racemusichnus jacobacciensis igen. isp. nov., ...
Lithofacies distribution of invertebrate and vertebrate trace-fossil assemblages in an Early Mesozoic ephemeral fluvio-lacustrine system from Argentina: Implications for the Scoyenia ichnofacies
(Elsevier Science, 2006-09)
This paper discusses the lithofacies distribution and ichnotaxonomic assignment of invertebrate, vertebrate and plant trace fossils in an Early Mesozoic ephemeral fluvio-lacustrine system from northwest Argentina. 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 ...
Fossil woods from the Eocene of Corcovado, Argentinean Patagonia: geological setting and conifer diversity
(International Association of Wood Anatomists, 2021-05)
Eocene paleofloras of Patagonia are diverse and increasingly known. A new assemblage of fossil wood has been recovered from Eocene sediments in Corcovado, western Argentinean Patagonia. The lithological succession (formerly ...
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 ...
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 ...
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 ...
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 ...
