High-Resolution Late Devonian Magnetostratigraphy From the Canning Basin, Western Australia: A Re-Evaluation [PDF]

open access: yesFrontiers in Earth Science, 2021
Late Devonian time was a period of rapid upheaval in the Earth system, including climate change, sea level changes, widespread ocean anoxia, and the Frasnian-Famennian mass extinction; the cause(s) of these changes remain(s) uncertain.

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.

Invasive species and biodiversity crises: testing the link in the late devonian. [PDF]

open access: yesPLoS ONE, 2010
During the Late Devonian Biodiversity Crisis, the primary driver of biodiversity decline was the dramatic reduction in speciation rates, not elevated extinction rates; however, the causes of speciation decline have been previously unstudied.

The expansion of land plants during the Late Devonian contributed to the marine mass extinction

open access: yesCommunications Earth & Environment, 2023
The evolution and expansion of land plants brought about one of the most dramatic shifts in the history of the Earth system — the birth of modern soils — and likely stimulated massive changes in marine biogeochemistry and climate.

Was there more space in the late Early Devonian for marine biodiversity to peak than in the early Late Ordovician?: A brief note [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2013
After the so-called “Cambrian explosion”, marine biodiversity peaked either in the early Late Ordovician (as shown by the “classical” curves based on the extensive palaeontological data compilation) or in the late Early Devonian (as shown by the

A new Late Devonian genus with seed plant affinities. [PDF]

open access: yesBMC Evol Biol, 2015
Many ovules of Late Devonian (Famennian) seed plants have been well studied. However, because few taxa occur with anatomically preserved stems and/or petioles, the vascular system of these earliest spermatophytes is little understood and available data come mostly from Euramerica.

Early sarcopterygian morphological disparity through the Devonian-Carboniferous crisis [PDF]

open access: yesScientific Reports
Major morphological adaptations characterized the early evolutionary history of sarcopterygians during the Devonian (419–359 Ma) and the Carboniferous (359–299 Ma), punctuated by environmental changes and biodiversity crises.

Pollen Organ Telangiopsis sp. of Late Devonian Seed Plant and Associated Vegetative Frond. [PDF]

open access: yesPLoS ONE, 2016
Pollen organ Telangiopsis sp., associated with but not attached to vegetative fronds, has been collected from the Upper Devonian (Famennian) Wutong Formation, Dongzhi County, Anhui Province, China. Fertile axes with terminal pollen organs are dichotomous
