Permian Large Igneous Provinces and Their Paleoenvironmental Effects

open access: yesGeophysical Monograph Series, Page 417-434., 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.

Discovery of Late Mississippian (late Serpukhovian)-Early Pennsylvanian (earliest Bashkirian?) foraminiferal assemblages from the Sanandaj-Sirjan Zone, Iran: Biostratigraphic and palaeoenvironmental implications. [PDF]

open access: yesGeol J (Chichester), 2023
The new discovery of the Late Mississippian (late Serpukhovian)–Early Pennsylvanian (early Bashkirian?) foraminiferal assemblages, providing the palaeoecological data about the upper Serpukhovian–lowermost Bashkirian? foraminiferal faunas, and identifying the depositional environments of the Sanandaj–Sirjan Zone during this time, as well as describing ...

Early evolutionary history of the seed. [PDF]

open access: yesBiol Rev Camb Philos Soc
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

The Late Pennsylvanian vegetation of the Donets Basin, Ukraine: Syntaxonomy of plant communities

open access: yesGeo&Bio, 2023
A reconstruction and classification of Kasimovian and Gzhelian plant communities of the Donets Basin that constituted the Late Pennsylvanian vegetation cover of the region is proposed.

First record of Gzhelian fusulinaceans from the Carboniferous of northern Spain

open access: yesSpanish Journal of Palaeontology, 2022
Several fusulinacean species of Gzhelian age have been found in a section close to the village of Asiego, in the northern part of Picos de Europa Massifs (Cantabrian Mountains). These specimens, which were collected in limestone beds from the upper part of the Puentelles Formation, belong to the genera Triticites, Rauserites, Jigulites, Ferganites and ...

New Hybondontoid Shark from the Permocarboniferous (Gzhelian—Asselian) of Guardia Pisano (Sardinia, Italy) [PDF]

open access: yesActa Palaeontologica Polonica, 2010
Numerous isolated teeth, fin spine fragments and dermal denticles of a hybodont shark from a lacustrine limestone horizon at the top of lithofacies B of the Late Carboniferous to Early Permian succession of the Guardia Pisano Basin (Sulcis area, southwestern Sardinia, Italy) are assigned to a new species of the genus Lissodus Brough, 1935.

Geometric morphometric analysis and taxonomic revision of the Gzhelian (Late Pennsylvanian) conodont Idiognathodus simulator from North America [PDF]

open access: yesActa Palaeontologica Polonica, 2016
A new morphometric approach was developed to study morphological variation within P1 elements commonly referred to as Idiognathodus simulator, which was selected to be the biostratigraphic marker for the base of the global Gzhelian Stage (Carboniferous).

Discovery of the First Blattinopsids of the Genus Glaphyrophlebia Handlirsch, 1906 (Paoliida: Blattinopsidae) in the Upper Carboniferous of Southern France and Spain and Hypothesis on the Diversification of the Family

open access: yesDiversity, 2022
Glaphyrophlebia victoiriensis sp. nov. (Paoliida: Blattinopsidae) is the third Gzhelian representative of the genus and is described based on a beautiful forewing from the Var department in Southern France.

Two episodes of Gzhelian (latest Carboniferous) volcanism immediately predate Asselian (early Permian) cooling and glaciation [PDF]

open access: yesGlobal and Planetary Change
The Skagerrak-Centered large igneous province (SCLIP) was active 299 million years ago when Earth’s climate transitioned into an interval of intensified glaciation.

Calcareous marine algae from the Carboniferous (Moscovian-Gzhelian) of the Cantabrian Zone (NW Spain)

open access: yesSpanish Journal of Palaeontology, 2021
A taxonomic revision of shallow-water Carboniferous (Pennsylvanian) red and green algae observed in Ponga, Picos de Europa and Pisuerga-Carrión Units in NW Spain is presented. Some microproblematics are included. Thirty-two genera are described; three genera and four species are new: Anatolipora cantabriensis n. sp., Pelayella multiporosa n.
