Extinction, dissolution, and possible ocean acidification prior to the Cretaceous/Paleogene (K/Pg) boundary in the tropical Pacific
Autor: Serena Dameron, Deborah J Thomas, Kenneth G. MacLeod, Kendra Clark, R. Mark Leckie, Jackie A. Lees
Publikováno v: Palaeogeography, Palaeoclimatology, Palaeoecology. 485:433-454
Biotic perturbations and changes in ocean circulation during the Maastrichtian stage of the latest Cretaceous raise questions about whether the biosphere was preconditioned for the end-Cretaceous mass extinction of calcareous plankton. A brief acme o

Autor: Marcelo de Araujo Carvalho, Andrea Concheyro, Gerson Fauth, Jackie A. Lees, Rodrigo do Monte Guerra, Renato Rodriguez Cabral Ramos
Publikováno v: Cretaceous Research. 56:550-562
This study reports on the most stratigraphically extensive nannofloras yet recovered from the Lachman Crags Member of the Santa Marta Formation, James Ross Island, Antarctic Peninsula. The productive samples are dated as early Campanian. These ages a

Autor: Jackie A. Lees, Nataliya Tur, John A. Breyer, Joan M. Spaw, Russell E. Hinote, Tobi Kosanke, Nancy Engelhardt-Moore, Richard A. Denne
Publikováno v: Palaeogeography, Palaeoclimatology, Palaeoecology. 413:2-28
The interbedded organic-rich marls and limestones of the Eagle Ford Group of South Texas were deposited on the shelf of the Central Texas Platform during the upper Cenomanian through the Turonian. Micropaleontological analyses of thin-sections and re

Pioneer nannofossil assemblages from the initial transgression of the Niobrara seaway in the Turonian, San Juan Basin, New Mexico, USA
Autor: Jackie A. Lees, Jonathan D. Schueth
Publikováno v: Marine Micropaleontology. 151:101771
Nannofossils of the North American Late Cretaceous Western Interior Seaway have been extensively studied, but these investigations have primarily focused on the diverse communities of the Niobrara and Greenhorn sea-level highstands. We lack a firm un
