Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

The albian-cenomanian boudary in the northern part of the Don-Medveditsa dislocations. Paper 1. The history of studying and the section descriptions [PDF]
Известия Саратовского университета. Новая серия: Серия Науки о ЗемлеThe Albian-Cenomanian rocks compose a single complex of terrigenous deposits over the Volga Region. Delineation of the boundaries of the Cretaceous system units generally tends to cause difficulties, accounted for by rare finds of the fossils.

Comptes Rendus. Géoscience, 2022 A tectonically-controlled forced regression occurred on the western margin of the French subalpine basin around the Aptian–Albian boundary. It nearly emptied the western part of the Vocontian Trough during the early and middle Albian.

Известия Саратовского университета. Новая серия: Серия Науки о ЗемлеAmmonite finds at the Miroshniki site, within the Albian-Cenomanian boundary interval, make it possible to identify the presence of the analogues of the Upper Albian zones Mortoniceras fallax (autochthonous burial within aleurolites) and Mortoniceras ...

Biostratigraphy of the Mauddud Formation from selected Boreholes, central Iraq
Iraqi Geological Journal, 2023 The Mauddud Formation was one of the important and widespread Lower Cretaceous period formations in Iraq. It has been studied in three wells (EB. 55, EB. 58, and EB. 59) within the East Baghdad Oil Field, Baghdad, central Iraq. 280 thin sections
