Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Widespread complex enameloid microstructure in teeth and rostral denticles of Cretaceous sclerorhynchoid skates (Rajiformes: †Sclerorhynchoidei). [PDF]
J AnatThis article demonstrates that the teeth and rostral denticles of an extinct clade of sawfish‐like skates display an extremely derived enameloid microstructure, similar to what is known among sharks. The presence of tooth‐like enameloid microstructure in dermal denticles opens new perspectives about the origins and development of chondrichthyan ...

Lower sea levels in the Middle Cenomanian
Carnets de Géologie, 2003 It has been known since the 1970's that the relatively high sea levels during the Cenomanian in southern England and northern France were interrupted by a strong fall in sea level early in the Middle Cenomanian.

Proceedings of the Geologists' Association, 2006 This review briefly outlines the historical background to the subdivision of the Chalk and the Upper Cretaceous in the Anglo-Paris Basin and contiguous areas, leading up to the introduction of the etage cenomanien in 1848, and the subsequent attempts to develop a zonal subdivision of the stage.
