First record of Gzhelian fusulinaceans from the Carboniferous of northern Spain

Spanish 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]

Acta 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.

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.).

Taxonomy and nomenclature of Sphenopteris and allied fossil‐genera of Carboniferous seed‐plant fronds

TAXON, Volume 72, Issue 4, Page 862-879, August 2023., 2023
Abstract Most remains of Carboniferous lyginopteridalean seed‐plant fronds used to be classified in a single fossil‐genus (Sphenopteris) based mainly on pinnule morphology. By incorporating additional characters linked to frond architecture and rachial features a more natural taxonomy has now been achieved.

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

Spanish 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.

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.

Paleopteran molecular clock: Time drift and recent acceleration. [PDF]

Ecol Evol
Constant evolution rates, which form the foundation of the strict molecular clock model, do not apply in the case of Paleoptera, highlighting a notable bias in the molecular clock hypothesis. The current biodiversity may be the outcome of a relatively recent, exponential increase in base substitution rates.

The Early History of Giant Cockroaches: Gyroblattids and Necymylacrids (Blattodea) of the Late Carboniferous

Diversity, 2023
Large-winged blattoids of the Middle to Late Pennsylvanian reveal a striking appearance, diversification, and decline in the fossil record. Among them, the families Necymylacridae Durden, 1969, and Gyroblattidae Durden, 1969, as well as the mylacrid ...
