The Boltysh impact structure formed 0.65 Ma after the K-Pg boundary, coincident with Lower C29n hyperthermal.

In this contribution, we describe latest Cretaceous aquatic plant communities from the La Colonia Formation, Patagonia, Argentina, based on their taxonomic components and paleoecological attributes. The La Colonia Formation is a geological unit deposited during a Maastrichtian-Danian transgressive episode of the South Atlantic Ocean. This event resulted in the deposition of a series of fine-gra...

Recovery of new decapod specimens from middle and late Eocene rocks of Pakistan prompted reevaluation of the known decapod fauna of the region. Specimens come from the Sulaiman Range in Balochistan, North-West Frontier, and Punjab provinces, and range temporally from the middle Lutetian through the Bartonian and possibly early Priabonian global marine ages. Proxicarpilius planifrons, Portunus s...

The marine ecosystem has been severely disturbed by several transient paleoenvironmental events (<200 kyr duration) during the early Paleogene, of which the Paleocene-Eocene Thermal Maximum (PETM, ~56 Ma) was the most prominent. Over the last decade a number of similar events of Paleocene and Eocene age have been discovered. However, relatively little attention has been paid to pre-PETM events,...
