Journal ArticleDOI
Climatic and biotic change in the late Triassic
TL;DR: The marine invertebrate fauna shows a significant turnover at the end of the Early Carnian and subsequently diversified prior to a major biotic turnover on the Carnian-Norian boundary.
Journal ArticleDOI
Conjunctive use of spectral gamma-ray logs and clay mineralogy in defining late Jurassic–early Cretaceous palaeoclimate change (Dorset, U.K.)
TL;DR: In this paper, the spectral gamma-ray (SGR) response of resultant sediments is compared with the influence of organic matter on SGR, showing that elevated thorium may be used as a proxy for humid palaeoweathering.
Journal ArticleDOI
Palaeoclimatic significance of changes in clay mineralogy across the Jurassic-Cretaceous boundary in England and France
TL;DR: Clay mineralogical changes across the Jurassic-Cretaceous boundary from the northern to the southern part of western Europe show similar patterns in: the mudrocks exposed on the Yorkshire Coast, the paralic sediments of the Dorset Wessex Basin, and the Jura and Vocontian Trough of S.E. France.

TL;DR: A multidisciplinary colligation including new data and analysis of the evidence for the climates of southern Britain during c. 140 Ma to c. 120 Ma BP (Berriasian-Barremian) is presented in this paper.
Journal ArticleDOI
Isotopic evidence for Late Jurassic-Early Cretaceous climate change
Darren R. Gröcke,Darren R. Gröcke,Gregory D. Price,Alastair Ruffell,Jörg Mutterlose,Evgenij Y. Baraboshkin +5 more
TL;DR: Strontium, oxygen-and carbon-isotope ratios have been determined from Late Jurassic-Early Cretaceous belemnites from the Volga Basin, Russia, and Kawhia Harbour, New Zealand.
