Albian Stage and Substage boundaries
Bulletin of the Geological Society of Denmark, 1984 The base of the Albian Stage has been defined in the European province at the earliest appearance of the ammonite Leymeriella ('Proleymeriella') schrammeni anterior Brinkmann, the earliest member of the important 'mid-Cretaceous' ammonite superfamily Acanthocerataceae. A type section in the Harz foredeep region of northern Germany has been proposed. A

The Anatomical Record, Volume 309, Issue 10, Page 2739-2751, October 2026.Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman
Journal of Petroleum Geology, Volume 49, Issue 4, Page 1179-1194, October 2026.ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.

Journal of Petroleum Geology, Volume 49, Issue 4, Page 1382-1411, October 2026.ABSTRACT The Pletmos sub‐basin in the Outeniqua Basin, offshore South Africa, is divided by the Superior, Pletmos and Plettenberg faults into northern and southern depocentres. In this study, geological and organic geochemical data together with 1D basin modelling were used to investigate the burial, thermal and maturation histories, and the timing of ...

The Depositional Record, Volume 12, Issue 4, September 2026.Allostratigraphically defined mudstone packages show marked along‐strike thickness variation, interpreted to be related to shifting thrust activity in the orogen; loading cycles lasted about 750 kyr. Close to the orogen, the forebulge is mantled by shelly sandstone whereas far from the orogen, the forebulge is typified by organic‐rich mudstone ...
