The Albian-Cenomanian boudary in the northern part of the Don-Medveditsa dislocations. Paper 2. Oryctocoenoses analysis. Conclusions [PDF]

Известия Саратовского университета. Новая серия: Серия Науки о Земле
Ammonite 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 ...

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 Земле
The 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.

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

Oyster-bioimmured ammonites from the Upper Albian of Annopol, Poland: stratigraphic and palaeobiogeographic implications [PDF]

, 2013
Ammonites Mortoniceras (Subschloenbachia) sp. are preserved as attachment scars on the oyster shells from the topmost portion of the Albian succession at Annopol, Poland. These oyster-bioimmured ammonites show a closest affinity to the representatives of

A first high-resolution carbon isotope stratigraphy from the Boreal (NW Germany) for the Berriasian to Coniacian interval—implications for the timing of the Aptian–Albian boundary

Frontiers in Earth Science, 2023
High-amplitude changes in sedimentary δ13C characterize the Cretaceous system and have been proven useful for supra-regional chemostratigraphic correlation.

A basal elasmosaurid plesiosaur from the upper Albian– lower Cenomanian? Cambridge Greensand

Acta Palaeontologica Polonica
An historical indeterminate elasmosaurid specimen CAMSM X50356 (CAMSM = Sedgwick Museum) collected during the 19th century is described. The specimen comes from the Cenomanian Cambridge Greensand although the possibility of an Albian–lower Cenomanian age
