Diversification of the Neoselachii (Chondrichthyes) during the Jurassic and Cretaceous [PDF]

open access: yes, 2006
The Neoselachii are a monophyletic group including all of the extant sharks and rays. They underwent rapid diversification throughout the Jurassic and Cretaceous, going from low-diversity assemblages of members of extinct orders in the Late Triassic to ...

A Paleotectonic Atlas of the African Plate: Permian to Recent

open access: yesJournal of Petroleum Geology, Volume 48, Issue 4, Page 231-279, October 2025.
ABSTRACT The fragmentary release of petroleum data defining the deep structure and stratigraphy of African basins has been integrated with existing literature to compile 19 tectonic maps over key geological intervals from Permian to Recent times. African plate margins range in their age of opening from Late Triassic (off Lebanon), through Early/Middle ...

A THEROPOD DOMINATED ICHNOCOENOSIS FROM LATE HAUTERIVIAN-EARLYBARREMIAN OF BORGO CELANO (GARGANO PROMONTORY, APULIA, SOUTHERN ITALY)

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2008
Several dinosaur footprints were discovered on three different levels cropping out in the CO.L.MAR quarry, south of the village of Borgo Celano in the Gargano Promontory (Apulia, southern Italy).

Reconciling strontium-isotope and K-Ar ages with biostratigraphy: the case of the Urgonian platform, Early Cretaceous of the Jura Mountains, Western Switzerland [PDF]

open access: yes, 2018
During the late Early Cretaceous, the shallow-water domains of the western Tethys are characterized by the widespread deposition of Urgonian-type carbonates rich in rudists, corals and other oligotrophic, shallow-marine organisms.

A Middle Cenomanian coral fauna from the Northern Calcareous Alps (Bavaria, Southern Germany) – new insights into the evolution of Mid-Cretaceous corals [PDF]

open access: yes, 2013
In the Northern Calcareous Alps, relics of a formerly widely distributed shallow marine facies belonging to the Branderfleck Formation (Upper Albian to Early Turonian) crop out and contain locally abundant corals.

Evolutionary systematics of the Staphylininae rove beetles (Coleoptera: Staphylinidae) resolved by integration of phylogenomics, comparative morphology and historical biogeography

open access: yesSystematic Entomology, Volume 50, Issue 4, Page 750-779, October 2025.
Higher classification of the rove beetle subfamily Staphylininae is revised based on novel phylogenomic, morphological and biogeographic evidence. Four new subtribes are described for Staphylininae; of them, two are for the tribe Tanygnathinini and two are for the tribe Staphylinini, and both tribes changed in composition due to other novelties ...

Valanginian-Hauterivian scleractinian coral communities from the Marseille region (SE France)

open access: yesCretaceous Research, 2009
Abstract Coral beds associated with Valanginian and Hauterivian platform carbonates from the Marseille region show two faunal assemblages corresponding with a Stylosmilia-Baryphyllia community (late Valanginian) and a Mesomorpha-Dimorpharaea community (early Hauterivian). The stratigraphic position of this fauna is based on the associate microfossils

Biostratigraphy, sedimentology and sequence stratigraphy of the latest Hauterivian - Early Barremian drowning episode of the Northern Tethyan margin (Altmann Member, Helvetic nappes, Switzerland) [PDF]

open access: yes, 2018
.: During the Early Cretaceous, major palaeoceanographic changes are mirrored on the northern Tethyan carbonate platform by changes in the carbonate factory and by platform drowning.

Micropaleontological observations on the Lower Cretaceous iron ore-related formations of the Mecsek Mts. (Upper Valanginian–Lower Hauterivian, South Hungary) [PDF]

open access: yes, 2018
The Late Valanginian–Early Hauterivian iron ore deposit and related formations at Zengővárkony (Mecsek Mts., South Hungary) provided a relatively rich microfauna of foraminifera, crustacean microcoprolites, and sponge spicules.

Trace elements, rare earth elements and isotopes of poorly preserved fossils from lower Cretaceous carbonates (Eastern Black Sea): Implications for early diagenetic alteration

open access: yesThe Depositional Record, Volume 11, Issue 4, Page 1107-1131, September 2025.
Analysing Rare Earth Elements (REEs) and other trace elements together with stable isotope data in poorly preserved belemnites can provide valuable insights into early diagenetic pathways, water‐interaction processes, and even potential redox conditions.
