Wildfire during deposition of the “Illinger Flözzone” (Heusweiler-Formation, “Stephanian B”, Kasimovian–Ghzelian) in the Saar-Nahe Basin (SW-Germany)

, 2020
Wildfires occurred more or less regularly in many Pennsylvanian ecosystems, not only in seasonally dry regions but also in the ever wet tropics. One of the reasons for this was probably the relatively high atmospheric oxygen conditions prevailing during ...

LATE CARBONIFEROUS BRACHIOPODS FROM KARAKORUM, PAKISTAN

Rivista Italiana di Paleontologia e Stratigrafia, 1999
Carboniferous rocks from North Karakorum display sharp lateral variations in lithology and thickness suggesting accumulation in half-grabens during continental rifting between the Karakorum block and northern Gondwana. Different Carboniferous successions,

The challenge of relating the Kasimovian to west European chronostratigraphy: a critical review of the Cantabrian and Barruelian substages of the Stephanian Stage

Geological Society, London, Special Publications, 2023
Abstract For the west European regional chronostratigraphic framework, the Cantabrian substage was conceived as covering a widely apparent stratigraphic gap between the top of the Westphalian and the base of Stephanian A, the lowest unit of the Stephanian.

Distal Marine Mercury Signals in Peak Late Paleozoic Ice Age: Implications for Aeolian Versus Volcanic Inputs

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract An investigation of the relationships among large igneous province (LIP), carbon cycling, and climate change is central to understanding Earth system. During Glacial III, the most intense phase of Late Paleozoic Ice Age, the influence of coeval LIP on the carbon cycle and climate remains debated.

Exhumation history of the Variscan suture: Constrains on the detrital zircon geochronology from Carboniferous–Permian sandstones (Northern Gemericum; Western Carpathians)

Geologica Carpathica, 2019
The Late Paleozoic sedimentary basins in the Northern Gemericum evolved gradually in time and space within the collisional tectonic regime of the Western Carpathian Variscan orogenic belt. The detrital zircon age spectra, obtained from the Mississippian,

New Zealand Geological Timescale 2025

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
New Zealand Geological Timescale 2025 (NZGT 2025) is the first comprehensive update and revision of the New Zealand Geological Timescale in a decade. The criteria used to establish age ranges of New Zealand Stages within the NZGT have been reviewed, calibrated, and revised where required against the 2023/04 International Chronostratigraphic Chart and ...

The neodiapsid Thadeosaurus colcanapi from the upper Permian of Madagascar

Papers in Palaeontology, Volume 11, Issue 2, March/April 2025.
Abstract The enigmatic neodiapsid Thadeosaurus colcanapi (Lower Sakamena Formation, southwestern Madagascar), sole species of the genus Thadeosaurus, is revised here. The attribution of 12 of the 21 referred specimens is confirmed, spanning all ontogenetic stages, and the anatomy of Thadeosaurus is redescribed in detail with comments on ontogenetical ...

A new cockroach (Blattodea, Rhipidoblattinidae) from the Toarcian (Lower Jurassic) of Alderton Hill, Gloucestershire, UK, and the earliest likely occurrence of aposematic colouration in cockroaches

Papers in Palaeontology, Volume 10, Issue 5, September/October 2024.
Abstract We describe the seventh valid species of cockroach, Alderblattina simmsi gen. et sp. nov., from insect‐rich strata recording the Toarcian Oceanic Anoxic Event (T‐OAE). The T‐OAE represents a period of extreme global warming and environmental change that drove palaeoecological pressures and evolutionary changes in marine and terrestrial ...

Late syn‐rift to early post‐rift basin fill dynamics of a mixed siliciclastic‐carbonate succession banked to a basement high, Hornsund, southwestern Spitsbergen, Arctic Norway

Basin Research, Volume 36, Issue 4, July–August 2024.
The depositional evolution of the ?Pennsylvanian – ?lower Permian Treskelodden Formation (Spitsbergen) is illustrated in the four conceptual block diagrams representing evolution from an alluvial/fluvial dominated environment in phase 1a and 1b (A, B), through a nearshore storm/tide dominated depositional environment in phase 2a + 2b (C), to a marine ...
