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.

TL;DR: In this paper, the authors examine the progressive development of footwall topography associated with a set of active normal faults in the northeastern Basin and Range Province of the western United States and show that patterns of catchment area, footwall relief, and catchment outlet spacing vary predictably and are related to the growth of the rangebounding normal fault array.

TL;DR: In this article, the atmospheric reentry of spherules arriving at distal sites is modeled using a two-phase fluid flow code, which includes ejecta and air opacities in a radiative transfer calculation, and the models predict a pulse of thermal radiation at the surface peaking at 5-15 kW/m 2, analogous to an oven set on "broil" (~260° C).

TL;DR: In this article, the authors proposed that the desiccation of flora by ejecta reentry, as well as the effects of postimpact global cooling/darkness, left much of the terrestrial flora prone to fires, and that the volume of soot in the global K-Pg layer is explained by a combination of syn- and postimpact wildfires.

TL;DR: In this article, the authors presented the first hydrocode simulations of the formation of the Sierra Madera structure (west Texas, USA), which was caused by an impact into a thick sedimentary target sequence.
