Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical 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.

Stripping back the modern to reveal the Cenomanian–Turonian climate and temperature gradient underneath [PDF]

open access: yesClimate of the Past, 2020
During past geological times, the Earth experienced several intervals of global warmth, but their driving factors remain equivocal. A careful appraisal of the main processes controlling past warm events is essential to inform future climates and ...

Middle Cenomanian coral fauna from the Roßsteinalmen (Northern Calcareous Alps, Bavaria, Southern Germany) – a revised and extended version [PDF]

open access: yesZitteliana, 2023
In the Northern Calcareous Alps, relics of a formerly widely distributed shallow marine facies belonging to the Branderfleck Formation (upper Albian to lower Turonian) crop out and contain locally abundant corals.

Vegetation and climate change at the southern margin of the Neo-Tethys during the Cenomanian (Late Cretaceous): Evidence from Egypt

open access: yesPLoS ONE, 2023
Changes in terrestrial vegetation during the mid-Cretaceous and their link to climate and environmental change are poorly understood. In this study, we use plant macrofossils and analysis of fossil pollen and spores from the Western Desert, Egypt, to ...

New information on the Cenomanian bothremydid turtle Algorachelus based on new, well-preserved material from Spain [PDF]

open access: yesFossil Record, 2018
Algorachelus peregrinus is the oldest representative of the crown group Pleurodira known in Laurasia. The type locality of this bothremydid is Algora, situated in central Spain, at levels deposited during the uppermost middle–lowermost upper ...

The new evidence of Albian – Cenomanian boundary biostratigraphy for first time from Iran

open access: yesJournal of Stratigraphy and Sedimentology Researches, 2012
The Sarvak Formation in Tang – e – Chenarbashi with 712 meters thickness encompasses Albian - Cenomanian planktonic foraminifera. In the studied section, surveying the Albian – Cenomanian boundary is indicated that Rotalipora appeninica Zone not be ...

Cenomanian-Turonian flooding cycles: U.S. Gulf Coast and Western Interior

open access: yesCretaceous research (Print), 2018
Cenomanian-Turonian ages, 100.5 Ma to 89.8 Ma, represented an extraordinary Cretaceous time interval when continental seaways expanded, tropical waters interchanged with Polar waters, global climates warmed, and at the end of the Cenomanian large amounts

Widespread complex enameloid microstructure in teeth and rostral denticles of Cretaceous sclerorhynchoid skates (Rajiformes: †Sclerorhynchoidei). [PDF]

open access: yesJ Anat
This 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

open access: yesCarnets 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.
