Compositional turnover and ecological changes related to the waxing and waning of glaciers during the Late Paleozoic Ice Age in ice-proximal regions (Pennsylvanian, Western Argentina)
(Paleontological Society, 2016-05)
The Late Palezoic Ice Age had a profound effect on the biota. Despite much research has been focused on paleotropical regions or global-scale analyses, regional ecological changes have seldom been studied in ice-proximal ...
Carbonate collapse and the late Paleozoic ice age marine biodiversity crisis
(Geological Society of America, 2020-02)
The late Paleozoic ice age (LPIA) was characterized by persistently low diversity of marine invertebrates following a second-order mass extinction. Here, we used a data set of North American (paleotropical) fossil occurrences ...
Carbonate collapse and the late Paleozoic ice age marine biodiversity crisis
(2020)
The late Paleozoic ice age (LPIA) was characterized by persistently low diversity of marine
invertebrates following a second-order mass extinction. Here, we used a data set of North
American (paleotropical) fossil ...
New invertebrate peri-glacial faunal assemblages in the Agua de Lucho formation, Río Blanco basin, Argentina: the most complete marine fossil record of the early mississippian in South America
(Pergamon-Elsevier Science Ltd, 2021-03)
A new fossil record of early Mississippian marine faunas is described from the Agua de Lucho Formation in the Sierra de las Minitas (La Rioja province, Río Blanco Basin, western Argentina). Considered Tournaisian in age ...
Global deglaciation and the re-appearance of microbial matground-dominated ecosystems in the late Paleozoic of Gondwana
(Wiley, 2013-07)
The extensive matgrounds in Carboniferous-Permian open-marine deposits of western Argentina constitute an anachronistic facies, because with the onset of penetrative bioturbation during the early Paleozoic microbial mats ...
A paleoclimatic reconstruction of the Carboniferous-Permian paleovalley fill in the eastern Paganzo Basin: Insights into glacial extent and deglaciation of southwestern Gondwana
(Pergamon-Elsevier Science Ltd, 2019-11)
During the mid-Carboniferous, ice centers located in present-day western Argentina disappeared until the late Cenozoic with glaciation of the Andes. The disappearance of mid-Carboniferous glaciers and the subsequent climate ...
Life in the late Paleozoic ice age: Trace fossils from glacially influenced deposits in a late carboniferous fjord of western Argentina
(Paleontological Society, 2011-05)
The early Late Carboniferous rocks of the Guandacol Formation in western Argentina preserve the glacial to postglacial transition. In the study area, this unit has been divided in three intervals: 1) a lower diamictitic ...
Glaciomarine sequence stratigraphy in the Mississippian Río Blanco Basin, Argentina, southwestern Gondwana: Basin analysis and palaeoclimatic implications for the Late Paleozoic Ice Age during the Tournaisian
(Geological Society Publications House, 2020-07)
The Late Paleozoic Ice Age (LPIA) has been well recorded in the uppermost Mississippian?Pennsylvanian of Gondwana. Nevertheless, little is known about the temporal and geographic dynamics, particularly during the early ...
