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.

A Synoptic Review of the Cartilaginous Fishes (Chondrichthyes: Holocephali, Elasmobranchii) from the Upper Jurassic Konservat-Lagerstätten of Southern Germany: Taxonomy, Diversity, and Faunal Relationships

open access: yesDiversity, 2023
The Late Jurassic-Early Cretaceous (164–100 Ma) represents one of the main transitional periods in life history. Recent studies unveiled a complex scenario in which abiotic and biotic factors and drivers on regional and global scales due to the ...

Late Jurassic salamandroid from western Liaoning, China [PDF]

open access: yesProceedings of the National Academy of Sciences, 2012
A Jurassic salamander, Beiyanerpeton jianpingensis (gen. et sp. nov.), from a recently found site in western Liaoning Province, China is the earliest known record of Salamandroidea. As a Late Jurassic record of the group, it extends the range of the clade by ~40 Ma.

A turiasaurian sauropod dinosaur from the Early Cretaceous Wealden Supergroup of the United Kingdom [PDF]

open access: yesPeerJ, 2019
The Jurassic/Cretaceous (J/K) boundary, 145 million years ago, has long been recognised as an extinction event or faunal turnover for sauropod dinosaurs, with many ‘basal’ lineages disappearing.

Palaeobiogeographical implications of the first fossil wood flora from the Jurassic of Turkey [PDF]

open access: yesActa Palaeontologica Polonica, 2022
We describe Jurassic fossilized woods from the Gümüşhane and Erzurum regions of Turkey that represent the eastern Sakarya Zone (eSZ) terrestrial biota. We collected 27 fossil wood fragments in total.

Late Jurassic–Early Cretaceous marine deoxygenation in NE Greenland [PDF]

open access: yesJournal of the Geological Society, 2023
The Late Jurassic–Early Cretaceous interval represents a prolonged marine deoxygenation period particularly in the Boreal–Arctic basins, the controlling factors of which remain poorly understood. Two drill cores totalling >450 m cover the Kimmeridgian–Barremian succession in contrasting locations in an evolving half-graben system (basin

open access: yesGeologija, 2022
In the southernmost outcrops of the Slovenian Basin the Middle Jurassic coarse-grained limestone breccia (mega)beds are interstratified within a succession that is otherwise dominated by hemipelagites and distal turbidites.
