Usolka section (southern Urals, Russia): a potential candidate for GSSP to define the base of the Gzhelian Stage in the global chronostratigraphic scale

Geologija, 2006
Conodont species Streptognathodus simulator Ellison, 1941 has been proposed recently to define the Kasimovian-Gzhelian boundary in the global chronostratigraphic scale.The species distributed globally and traditionally has been used as a marker of the ...

First report of silicified wood from a late Pennsylvanian intramontane basin in the Pyrenees: systematic affinities and palaeoecological implications

Papers in Palaeontology, Volume 9, Issue 5, September/October 2023., 2023
Abstract The first anatomically preserved wood specimens of an upland Carboniferous flora from the Iberian Peninsula are reported from the Erillcastell Basin (Eastern Pyrenees, Catalonia, Spain). Two taxa are described, a calamitacean Equisetales (Arthropitys sp.) and a Cordaitales (Dadoxylon sp.).

Decoding the drivers of deep‐time wetland biodiversity: insights from an early Permian tropical lake ecosystem

Palaeontology, Volume 66, Issue 3, May/June 2023., 2023
Abstract Wetlands are important to continental evolution, providing both arenas and refugia for emerging and declining biotas. This significance and the high preservation potential make the resulting fossiliferous deposits essential for our understanding of past and future biodiversity.

Skeletal and soft tissue completeness of the acanthodian fossil record

Palaeontology, Volume 65, Issue 4, July/August 2022., 2022
Abstract Acanthodians are a poorly understood paraphyletic grade of extinct Palaeozoic fishes. They play an increasingly prominent role in our understanding of vertebrate evolution as part of the chondrichthyan stem‐group even though their evolutionary history is scarce. The limited preservation of their mostly cartilaginous skeleton largely results in

Palaeoecological features of Lower Asselian (Lower Permian) carbonate skeletal mounds in the Pisanyi Kamen’ section (Un’ya River, Northern Urals)

The Depositional Record, Volume 7, Issue 2, Page 311-332, June 2021., 2021
The Pisanyi Kamen’ section on the Un'ya River, Northern Urals, from the Lower Asselian stratigraphic interval is the central part of a succession of skeletal mounds that are composed of biocementstones. Palaeoecological analysis allows the pioneer stages of the ecological succession, representing the stabilisation and colonisation stages, to be ...

Quartzite procurement in conglomerates and deposits: Geoarchaeological characterization of potential catchment areas in the central part of the Cantabrian Region, Spain

Geoarchaeology, Volume 36, Issue 3, Page 490-510, May/June 2021., 2021
A comprehensive geoarchaeological research project based on the integration of a geographic information system, field survey, stereomicroscopy, and thin‐section petrography, is presented to characterize potential procurement areas of quartzite. The application of this methodology in the Deva, Cares, and Güeña valleys and in three different geological ...
