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: The Yucatan Peninsula karst aquifer is one of the most extensive and spectacular KK aquifer systems on the planet as discussed by the authors, which is located in the vicinity of the North American/Caribbean plate boundary.

TL;DR: The only known impact structure on Earth with an unequivocal peak ring is Chicxulub as discussed by the authors, but it is buried and only accessible through drilling, and it is not accessible to the public.

TL;DR: It is concluded that the Porites corals at the field site were not able to acclimatize enough to prevent the impacts of local ocean acidification on their skeletal growth and development, despite spending their entire lifespan in low pH, low Ωarag seawater.

TL;DR: In-situ chemical and biological data indicate that both coral species richness and coral colony size decline with increasing proximity to low-saturation, low-pH waters at the ojo centers, and may indicate that today’s more complex frame-building species may be replaced by smaller, possibly patchy, colonies of only a few species along the Mesoamerican Barrier Reef.
