Endocerids: suspension feeding nautiloids?
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. Expand
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. Expand
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 approximatelyExpand
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 scientistsExpand
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 peakExpand
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 RaupianExpand
Classification of the Late Paleozoic Family Medlicottiidae Karpinsky (Ammonoidea)
This paper briefly discusses changes in phylogenetic reconstructions and in opinions on the system of the family Medlicottiidae Karpinsky. The most recent version of the classification, proposed inExpand
Biotic Crises and Giantism of Radiolarian Skeletons in the Late Paleozoic
The phenomenon of giantism and minimalism in the skeleton of Late Paleozoic radiolarians is very unusually and has not yet been studied. However, this is not ugliness, but inherited morphologicalExpand
Morphological Diversity of the External Shell Sculpture of Paleozoic Cephalopods: How Did It Arise and What Does It Mean?
The sculpture of the external shell of cephalopods, along with the shell shape, is one of the most characteristic morphological features. Sometimes (especially in the English-language literature)Expand
Nautiloid cephalopods from the Rickard Hill facies of the Saugerties Member of the Schoharie Formation, eastern New York, USA (late Emsian, Devonian): A case study in taphonomy from glacial erratics
Glacial erratics belonging to the Rickard Hill facies (RHf) of the Saugerties Member of the Schoharie Formation (late Emsian, Devonian) occur scattered throughout the Lower Hudson Valley of New YorkExpand

The cephalopod macrosystem: A historical review, the present state of knowledge, and unsolved problems: 2. Classification of nautiloid cephalopods
Major classifications of nautiloid cephalopods are critically reviewed. It is suggested that this cephalopod group is subdivided into 5 subclasses and 17 orders: Ellesmeroceratoidea (including theExpand
The cephalopod macrosystem: A historical review, the present state of knowledge, and unsolved problems: 3. Classification of Bactritoidea and Ammonoidea
TLDR
A new classification is proposed in which Bactritoidea and Ammonoidea are considered as subclasses, and a single order, Bactritida is included. Expand
The “Age of Crinoids”: A Mississippian Biodiversity Spike Coincident with Widespread Carbonate Ramps
Abstract Crinoids reached their highest generic richness and overall abundance during the Mississippian, which thus has been dubbed the Age of Crinoids. The causes are hypothesized to be from theExpand
Adaptive evolution in Paleozoic coiled cephalopods
TLDR
The general trends of decreasing mean origination and extinction rates during the Paleozoic are interpreted to reflect a successive stabilization of the coiled cephalopod assemblages. Expand
The evolutionary history of shell geometry in Paleozoic ammonoids
Abstract Tracking the geometry of all 597 ammonoid genera from the Lower Devonian into the Lower Triassic, a 145-Myr period that spans three mass extinctions, shows that Paleozoic ammonoid shellExpand
Morphological pathways in the evolution of Early and Middle Devonian ammonoids
TLDR
Reconstruction of the evolutionary history of these ammonoid morphs reflects the existence of two major phylogenetic lineages, both already visible in Early Devonian faunas. Expand
The A‐mode sutural ontogeny in prolecanitid ammonoids
TLDR
The generally accepted theory of a U-mode sutural ontogeny of prolecanitid ammonoids and their descendants is refuted and suturally nomenclature of Permian ceratites and Mesozoic ammonoids has to be modified. Expand
Climate during Permian-Triassic Biosphere Reorganizations, Article 1: Climate of the Early Permian
The Permian was marked by transition from the glacioera to the thermoera, the last one in the geo- logical history. This global climatic reorganization followed the significant paleogeographicExpand
