Impact Dating The large mass extinction of terrestrial and marine life—most notably, non-avian dinosaurs—occurred around 66 million years ago, at the boundary between the Cretaceous and Paleogene periods. But attributing the cause to a large asteroid impact depends on precisely dating material from the impact with indicators of ecological stress and environmental change in the rock record. Renne et al. (p. 684; see the Perspective by Pälike) acquired high-precision radiometric dates of… Expand
Tempo and duration of short-term environmental perturbations across the Cretaceous-Paleogene boundary
The complex interplay between extraterrestrial events and earth-bound processes that triggered one of the greatest biological crises of the Phanerozoic requires a high resolution timescale. DetailedExpand
Impact and Extinction
TLDR
Renne et al. (4) provide new evidence that the age of Chicxulub asteroid impact and the K-Pg boundary coincide precisely, and suggest that the most recent mass extinction at the Cretaceous-Paleogene (K-Pg) boundary was caused by an impact of a large asteroid or comet. Expand
Resolving the timing of events around the Cretaceous-Paleogene Boundary
Author(s): Sprain, Courtney Jean | Advisor(s): Renne, Paul R | Abstract: Despite decades of study, the exact cause of the Cretaceous-Paleogene boundary (KPB) mass extinction remains contentious.Expand
Marine bivalve records of Antarctic seasonality and biological responses to environmental change over the Cretaceous-Paleogene mass extinction interval
The Cretaceous-Paleogene mass extinction event occurred 66 million years ago and had a profound effect on the course of evolutionary history, with the extinction of up to 75% of life and largerExpand
The eruptive tempo of Deccan volcanism in relation to the Cretaceous-Paleogene boundary
TLDR
It is found that the DT did not erupt in three discrete large pulses and that >90% of DT volume erupted in <1 million years, with ~75% emplaced post-KPB, suggesting that either the release of climate-modifying gases is not directly related to eruptive volume or DT volcanism was not the source of Late Cretaceous climate change. Expand
State shift in Deccan volcanism at the Cretaceous-Paleogene boundary, possibly induced by impact
TLDR
High-precision dating of Deccan Traps volcanic units suggests an increase in volcanism associated with the Chicxulub impact, which suggests postextinction recovery of marine ecosystems was probably suppressed until after the accelerated volcanism waned. Expand
End-Cretaceous extinction in Antarctica linked to both Deccan volcanism and meteorite impact via climate change
TLDR
Species extinction at Seymour Island occurred in two pulses that coincide with the two observed warming events, directly linking the end-Cretaceous extinction at this site to both volcanic and meteorite events via climate change. Expand
Orbital control on the timing of oceanic anoxia in the Late Cretaceous
Abstract. The oceans at the time of the Cenomanian–Turonian transition were abruptly perturbed by a period of bottom-water anoxia. This led to the brief but widespread deposition of blackExpand
Macrofossil evidence for a rapid and severe Cretaceous–Paleogene mass extinction in Antarctica
TLDR
It is shown that the extinction was rapid and severe in Antarctica, with no significant biotic decline during the latest Cretaceous, contrary to previous studies. Expand
U-Pb constraints on pulsed eruption of the Deccan Traps across the end-Cretaceous mass extinction
TLDR
According to this model, maximum eruption rates occurred before and after the K-Pg extinction, with one such pulse initiating tens of thousands of years prior to both the bolide impact and extinction. Expand

The Chicxulub Asteroid Impact and Mass Extinction at the Cretaceous-Paleogene Boundary
TLDR
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. Expand
CONSEQUENCES OF THE CRETACEOUS/PALEOGENE MASS EXTINCTION FOR MARINE ECOSYSTEMS
▪ Abstract One of the greatest mass extinctions in Earth's history occurred at the end of the Cretaceous era, sixty-five million years (Myr) ago. Considerable evidence indicates that the impact of aExpand
Correlated terrestrial and marine evidence for global climate changes before mass extinction at the Cretaceous–Paleogene boundary
TLDR
Paleotemperatures for the last ≈1.1 million years of the Cretaceous are estimated by using fossil plants from North Dakota and employ paleomagnetic stratigraphy to correlate the results to foraminiferal paleoclimatic data from four middle- and high-latitude sites, suggesting a coupling of pCO2 and temperature.

Cretaceous climate, volcanism, impacts, and biotic effects
Abstract Cretaceous volcanic activities (LIPs and CFBPs) appear to have had relatively minor biotic effects, at least at the generic level. Major biotic stress during the Cretaceous was associatedExpand
The Phanerozoic Record of Global Sea-Level Change
TLDR
Long-term sea level peaked at 100 ± 50 meters during the Cretaceous, implying that ocean-crust production rates were much lower than previously inferred, and presents a new sea-level record for the past 100 million years. Expand
