Palaeobiology and evolutionary context of Angulithes mermeti, a streamlined early Late Cretaceous shallow-water nautiloid [PDF]

open access: yesActa Palaeontologica Polonica, 2019
Cretaceous nautiloids are commonly characterized by inflated shells and prolonged stratigraphic ranges. In the Albian, the species of Angulithes appeared and compressed, short-lived forms with narrow venters emerged during the Cenomanian age.

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

open access: yesИзвестия 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 ...

Cenomanian Ammonite Zones [PDF]

open access: yesGeological Magazine, 1960
A preliminary statement is made concerning the ammonite genera which have been used in defining the upper Cenomanian (Cretaceous) in Britain. The relations, positions, and characteristics of species of Mantelliceras, Metoicoceras, Utaturiceras, and Protacanthoceras are briefly explained and the need for a change in zonal nomenclature of the uppermost ...

The albian-cenomanian boudary in the northern part of the Don-Medveditsa dislocations. Paper 1. The history of studying and the section descriptions [PDF]

open access: yesИзвестия 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.
