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 late-surviving stem-ctenophore from the Late Devonian of Miguasha (Canada). [PDF]

open access: yesSci Rep, 2021
AbstractLike other soft-bodied organisms, ctenophores (comb jellies) produce fossils only under exceptional taphonomic conditions. Here, we present the first record of a Late Devonian ctenophore from the Escuminac Formation from Miguasha in eastern Canada.

An examination of the Devonian fishes of Michigan [PDF]

open access: yesPeerJ, 2018
We surveyed the taxa, ecosystems, and localities of the Devonian fishes of Michigan to provide a framework for renewed study, to learn about the diversity and number of these fishes, and to investigate their connection to other North American faunas ...

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

Late Devonian (Famennian) Chondrichthyes from Mexico [PDF]

open access: yesJournal of Vertebrate Paleontology, 2019
The Paleozoic vertebrate fossil record from Mexico is very scarce and strongly biased by rock exposure, composed mainly of upper Paleozoic (Carboniferous and Permian) outcrops (e.g., Sánchez-Zavala et al., 1999; Poole et al., 2005; González- Rodríguez et al., 2013).

An exceptionally preserved transitional lungfish from the lower permian of Nebraska, USA, and the origin of modern lungfishes. [PDF]

open access: yesPLoS ONE, 2014
Complete, exceptionally-preserved skulls of the Permian lungfish Persephonichthys chthonica gen. et sp. nov. are described. Persephonichthys chthonica is unique among post-Devonian lungfishes in preserving portions of the neurocranium, permitting ...

Enhanced continental weathering and its marine environmental effects in the late Devonian: Constraints from strontium isotopes of carbonate rocks in South China

open access: yes地质科技通报, 2022
The Frasnian-Famennian extinction in the late Devonian was one of the largest mass extinction during Earth's history, which was believed to be caused by the plant landing-indued intensification of terrestrial chemical weathering and the consequent ...
