TLDR
A new hypothesis is proposed and debated: according to it, the endocerids were planktotrophic cephalopods and the largest of them were giant suspension feeders.

Cephalopod embryonic shells as a tool to reconstruct reproductive strategies in extinct taxa

An exhaustive study of existing data on the relationship between egg size and maximum size of embryonic shells in 42 species of extant cephalopods demonstrated that these values are approximately

The paper aims to introduce the history of Russian and Soviet study of Permian ammonoids, from the middle of the 19th century to the present, to a wider audience of geologists, and particularly to a

THREE NEW SPECIES OF NAUTILIDS (CEPHALOPODS) FROM THE CARBONIFEROUS OF DONETS BASIN (EASTERN UKRAINE)

  • V. Dernov

  • 2021
TLDR
Three new species of nautilids have been described from the Carboniferous of the Donets Basin (Ukraine) and the new data are expanding the taxonomic composition of the genera Gzheloceras, Knightocer as, and PlanetocerAs and also clarify their geographical distribution.

Vertical escape tactics and movement potential of orthoconic cephalopods

TLDR
The current experiments suggest that orthocones sacrifice horizontal mobility and maneuverability in exchange for highly streamlined, vertically-stable, upwardly-motile conchs.

The 90th Anniversary of the Borissiak Paleontological Institute, Russian Academy of Sciences: from the “Golden Age” of Paleontology to New Perspectives

The main directions and results of the Paleontological Institute’s activities over the past 40 years are considered. The demand for paleontological research conducted by the Institute’s scientists

Lituitid cephalopods from the upper Darriwilian and basal Sandbian (Middle–Upper Ordovician) of Estonia

ABSTRACT Cephalopods of the order Lituitida Starobogatov, 1983 from the late Darriwilian and early Sandbian strata of Estonia are revised herein. During that time, the lituitids reached their peak

The morphospace of Late Permian coiled nautiloids

Occurrences of Late Permian coiled nautiloids are widespread but they have never been analysed in terms of spatial and temporal disparity changes. Morphometric analyses using the cardinal Raupian

Classification of the Late Paleozoic Family Medlicottiidae Karpinsky (Ammonoidea)

TLDR
The most recent version of the classification, proposed in the revised Treatise … (Furnish et al., 2009) is critically reviewed and the classification accepted by the present author is substantiated.

APPLICATION OF NATURAL MARINE MATERIALS: OPPORTUNITIES AND CHALLENGES

TLDR
This review provides examples of current and potential applications of compounds from aquatic organisms in various fields of industry and describes strategies for biomedical use of biologically active compounds from marine organisms.
