Cretaceous
JM Hancock, PF Rawson - Geological Society, London, Memoirs, 1992 - lyellcollection.org
Abstract Early Cretaceous The Cretaceous Period lasted for about 70 million years. During
this time there was a major change in the sedimentary history of the area as tectonism died
down and deposition started of an extensive blanket of coccolith ooze: the Chalk. The
change took place mainly over a brief interval across the Albian/Cenomanian (Lower/Upper
Cretaceous) boundary, at about 95 Ma. Until that time crustal extension along the Arctic-
North Atlantic megarifts continued to influence the tectonic evolution of northwest Europe …

[PDF][PDF] The Cretaceous/Tertiary mass extinction event in the northern Atlantic Coastal Plain
WB Gallagher - The Mosasaur, 1993 - researchgate.net
The Inner Coastal Plain in New Jersey and Delmarva is underlain by a Campanian (Upper
Cretaceous) to Thanetian (Paleocene) stratigraphic sequence containing fossil
assemblages from before, during and after the K/T boundary mass extinction event. The
lithostratigraphic framework and the microfossii zonation of these faunal changes is
reviewed. Microstratigraphic analysis of the sequence reveals that dominant marine
organisms of the Upper Cretaceous such as ammonites and oysters are selectively …

The Cretaceous-tertiary biotic transition
Mass extinctions are recognized through the study of fossil groups across event horizons,
and from analyses of long-term trends in taxonomic richness and diversity. Both approaches
have inherent flaws, and data that once seemed reliable can be readily superseded by the
discovery of new fossils and/or the application of new analytical techniques. Herein the
current state of the Cretaceous-Tertiary (KT) biostratigraphical record is reviewed for most
major fossil clades, including: calcareous nannoplankton, dinoflagellates, diatoms …
