Stratigraphy and Geological Correlation, 2011
The Vazhnan Formation, formerly attributed to the Sakmarian is now shown to be of the Gzhelian-Asselian age. Accordingly it is correlative with the concurrent Zaladou Formation of Central Iran and Dorud Group of Alborz. This suggests a vast transgression that covered the greater part of the Iranian territory in the terminal Carboniferous-initial ...

Orbital‐scale Climate Dynamics may Impact Gzhelian Peatland Wildfire Activity in the Ordos Basin
Acta Geologica SinicaAbstract The Carboniferous, an important coal‐forming period in geological history, was characterized by extensive vegetation and high oxygen levels. Evidence suggests frequent wildfires took place during this time, especially in peatlands.

, 2022 Three outcrops of the Gzhelian-aged Skelley Limestone (Casselman Formation, Conemaugh Group) were explored for vertebrate macrofossils and vertebrate microremains. The purpose of this exploration was to construct a better ecological history of the marine communities in the Late Pennsylvanian of eastern Ohio.

Botrychiopsis is an important biostratigraphic index taxon for Carboniferous–early Permian plant fossil successions of Gondwana. Its species have wide geographic distributions, restricted chronostratigraphic ranges, and are associated with diverse groups of plant associations.

Stratigraphy, 2008
The conodont species Streptognathodus simulator Ellison 1941 has been proposed to define the Kasimovian-Gzhelian boundary of the global chronostratigraphic scale based in part on its global distribution (Heckel et al. 2005). Traditionally St. simulator has been used as a marker of the base of the Gzhelian Stage in the type sections in Moscow Basin and ...

Fasciculate rugose corals from Gzhelian and Lower Permian strata, Pequop Mountains, northeast Nevada
Journal of Paleontology, 2008Upper Carboniferous and Lower Permian shallow marine rocks in the Pequop Mountains of northeastern Nevada contain an abundance of fossils, especially fusulinids and fasciculate corals. As the composite stratigraphic section in this area represents the most nearly complete sequence of this type of ...
