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.

Devonian in Turkey — a review

open access: yesGeologica Carpathica, 2010
Devonian in Turkey — a reviewThe Devonian Period is represented in Turkey by almost complete non-metamorphic sections of more than 1000 meters, which exhibit varying lithofacial associations. They are parts of thick Paleozoic sedimentary successions in the Pontides, Taurides and Arabian Plate.

A new Early Devonian antiarch placoderm from Belarus, and the phylogeny of Asterolepidoidei [PDF]

open access: yesActa Palaeontologica Polonica, 2023
A new asterolepidoid antiarch, Sherbonaspis talimaae sp. nov., is described based on the disarticulated skeletal elements from several boreholes in Belarus, from the Lepel Beds of the Vitebsk Formation, which has been assigned to an Early Devonian, late ...

Was the Devonian placoderm Titanichthys a suspension feeder? [PDF]

open access: yesRoyal Society Open Science, 2020
Large nektonic suspension feeders have evolved multiple times. The apparent trend among apex predators for some evolving into feeding on small zooplankton is of interest for understanding the associated shifts in anatomy and behaviour, while the spatial ...

Quantitative approach by miospores of the Devonian-Carboniferous transition [PDF]

open access: yes, 2022
The abundance of selected species at geological scale has been noted to be a useful criterium to correlate sedimentary sequences. In this work, we take as an example two groups of species, the lepidophyta and pusillites, which are noted to characterize ...
