The end-Cretaceous Chicxulub impact triggered Earth’s last mass-extinction, extinguishing ~ 75% of species diversity and facilitating a global ecological shift to mammal-dominated biomes. Temporal details of the impact event on a fine scale (hour-to-day), important to understanding the early trajectory of mass-extinction, have largely eluded previous studies. This study employs histological and histo-isotopic analyses of fossil fish that were coeval with a unique impact-triggered mass-death…

The Chicxulub Asteroid Impact and Mass Extinction at the Cretaceous-Paleogene Boundary
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.
Rapid ocean acidification and protracted Earth system recovery followed the end-Cretaceous Chicxulub impact
It is shown that the impact caused rapid ocean acidification, and that the resulting ecological collapse in the oceans had long-lasting effects for global carbon cycling and climate, and insights into the drivers of the last mass extinction, the recovery of marine carbon cycling in a postextinction world are provided.
Palaeobotanical evidence for a June 'impact winter' at the Cretaceous/Tertiary boundary
A LARGE bolide impact, such as that thought to have occurred at the Cretaceous/Tertiary (K/T) boundary, should produce large amounts of light-attenuating debris, thereby causing an 'impact
Late Cretaceous restructuring of terrestrial communities facilitated the end-Cretaceous mass extinction in North America
Changes in dinosaur richness had a negative impact on the robustness of Maastrichtian ecosystems against environmental perturbations, and earlier ecological restructuring may have exacerbated the impact and severity of the end-Cretaceous extinction, at least in North America.
Asteroid impact, not volcanism, caused the end-Cretaceous dinosaur extinction
The results support the asteroid impact as the main driver of the non-avian dinosaur extinction, by contrast, induced warming from volcanism mitigated the most extreme effects of asteroid impact, potentially reducing the extinction severity.
A seismically induced onshore surge deposit at the KPg boundary, North Dakota
High-resolution chronology of the immediate aftereffects of the Chicxulub impact event in the Western Interior is presented, and an impact-triggered onshore mix of marine and terrestrial sedimentation is reported—potentially a significant advancement for eventually resolving both the complex dynamics of debris ejection and the full nature and extent of biotic disruptions that took place in the first moments postimpact.

There is overwhelming evidence, based on the distribution of distinctive sediments and fossils and oxygen isotope data, that the climate of the Mesozoic world was appreciably more equable than that
Sturgeon rivers: an introduction to acipenseriform biogeography and life history
We present an overview of the global distribution of all 27 living species of Acipenseriformes in an attempt to understand their biogeographic history and the range of life history patterns displayed
Biology and conservation of sturgeon and paddlefish
Stocks of sturgeons are dramatically decreasing, particularly in Eurasia; the world sturgeon catch was nearly 28,000 t in 1982 and less than 2,000T by 1999 and this decline resulted from overfishing and environmental degradation such as: accumulation of pollutants in sediments, damming of rivers, and restricting water flows, which becomeunfavorable to migration and reproduction.
