Improvement in survivorship: The key for population recovery? [PDF]
, 2016 In northern Patagonia, commercial harvesting of South American sea lions, Otaria flavescens, from 1920 to 1960, decimated its population abundance. Population recovery was not immediate after hunting ceased in 1962.

Bipolar flaking as a component of a supraregional lithic resource base: A comparative study of cores from the Pampean and Northcentral Patagonian Atlantic coasts (Argentina) [PDF]
, 2018 Several authors argue that bipolar technology is an expeditious and versatile strategy, efficient for the reduction of small nodules. However, few studies analyze the use of bipolar reduction in relation to the lithic environmental supply. At the Pampean

Paleogene Pseudoglyptodont Xenarthrans from Central Chile and Argentine Patagonia [PDF]
American Museum Novitates, 2006 Herein we describe a new, large-bodied species of Pseudoglyptodon, a close sloth ally, from volcaniclastic deposits of the Abanico (5 Coya-Machalo´) Formation of the central Chilean Andean Main Range. This species, P. chilensis, is a rare element of the Tinguiririca Fauna, on which the recently formalized Tinguirirican South American Land Mammal ‘‘Age’’

Reptilian coprolites in the Eocene of central Patagonia, Argentina
Journal of Paleontology, 2012 Biogenic structures, herein interpreted as coprolites, were recorded in the ?upper Paleocene–Eocene Las Flores Formation, southeast Argentina. The coprolite origin is supported by several features, such as recurrent extrusive external morphology, longitudinal wrinkles, flattening of the ventral side, concentric and radial cracks, cryptocrystalline ...

Geophysical Monograph Series, Page 169-190., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
