The Chicxulub Asteroid Impact and Mass Extinction at the Cretaceous-Paleogene Boundary

TL;DR: Records of the global stratigraphy across this boundary are synthesized to assess the proposed causes of the Cretaceous-Paleogene boundary and conclude that the Chicxulub impact triggered the mass extinction.
Journal ArticleDOI

Deep-sea paleotemperature record of extreme warmth during the Cretaceous

TL;DR: Oxygen isotope analyses of well-preserved foraminifera from Blake Nose (30°N paleolatitude, North Atlantic) and globally distributed deep-sea sites provide a long-term paleotemperature record for the late Albian-Maastrichtian interval that is difficult to reconcile with the existence of significant Cretaceous ice sheets as discussed by the authors.
Journal ArticleDOI

Formation of the Isthmus of Panama

TL;DR: An exhaustive review and reanalysis of geological, paleontological, and molecular records converge upon a cohesive narrative of gradually emerging land and constricting seaways, with formation of the Isthmus of Panama sensu stricto around 2.8 Ma.
Journal ArticleDOI

The Heartbeat of the Oligocene Climate System

TL;DR: A 13-million-year continuous record of Oligocene climate from the equatorial Pacific reveals a pronounced “heartbeat” in the global carbon cycle and periodicity of glaciations.
