Belemnites are an extinct group of Mesozoic coleoid cephalopods with a fossil record
ranging from the early Late Triassic [about 240 million years ago (Mya)] to the Cretaceous …

Molluscs comprise the second largest phylum of animals (after arthropods), occurring in
virtually all habitats. Some are commercially important, a few are pests and some carry …

We describe an exceptionally well-preserved vampyropod, Syllipsimopodi bideni gen. et sp.
nov., from the Carboniferous (Mississippian) Bear Gulch Lagerstätte of Montana, USA. The …

Coleoidea (squids and octopuses) comprise all crown group cephalopods except the
Nautilida. Coleoids are characterized by internal shell (endocochleate), ink sac and arm …

Carbonate skeletons of fossil marine organisms are widely used to reconstruct
palaeoceanographic parameters. Specifically, the geochemistry of Jurassic and Cretaceous …

Orthoconic cephalopods are subordinate, but persistent, widespread and regionally
abundant components of Triassic marine ecosystems. Here, we describe unpublished …

Belemnites, a group of extinct coleoid cephalopods, were important components of
Mesozoic marine ecosystems. Their calcitic rostra are extensively used in biostratigraphy …

We describe four complete specimens of the early squid-like cephalopod Clarkeiteuthis
conocauda from the Toarcian Posidonienschiefer (Jurassic) each preserved with the bony …

Macrofossil calcite is of great importance for quantitative reconstructions of
palaeoenvironment and palaeoseasonality. The calcite rostra of belemnites, Jurassic to …

The phylogenetic origin and the timing of origination of the D ecabrachia are controversial.
This is due to a poor understanding of character complexes relating to the shell, which …
