(Academic Press Ltd - Elsevier Science Ltd, 2018-05)
The lowermost part of the Agua de la Mula Member (upper Hauterivian), Agrio Formation, was studied in distal depositional settings at four locations in the central Neuquén Basin. Detailed sedimentological and ichnological ...
Paleoecologic trends of Devonian Malvinokaffric fauna from the Paraná Basin as evidenced by trace fossils
(2021-08-01)
The Malvinokaffric Realm is an endemic paleogeographic region that inhabited Gondwanan high latitude seas during Early-Middle Devonian times. The causes for the collapse of this fauna are still debated but seem to be related ...
Biogenic reworking patterns in highly bioturbated shallow-marine transgressive successions (Jurassic, Neuquén Basin, Argentina)
(International Association of Sedimentology, 2019)
Thick (10s of m) successions of highly bioturbated, storm-influenced shallow-marine deposits are relatively uncommon in the rock record. Some examples have been reported from retrogradational successions associated with ...
