Biochron

TL;DR: The authors quantitatively analyzed benthic foraminiferal assemblages in order to reveal biotic and paleoenvironmental trends in the Paleocene section of Gebel Aweina, Egypt, on the southern Tethyan shelf.

TL;DR: In this article, the authors studied Upper Cretaceous and Lower Paleogene benthic foraminifera from the Agost section (southeastern Spain) to infer paleobathymetrical changes and paleoenvironmental turnover across the K/P transition.

TL;DR: This article proposed a new definition for the Epivillafranchian as a biochron included within the Praemegaceros verticornis FO/Bison menneri FO, and Crocuta crocuta FO.

TL;DR: Aalenian sediments have been studied in 10 sections located in the western part of the Basque-Cantabrian Basin (northern Spain) as discussed by the authors, and a close relationship between changes in seawater temperature and the observed changes observed in the foraminiferal and in the ammonoids assemblages has been evidenced.
