First teuthid cephalopod from the Lower Jurassic of South America (Neuquén Basin, Argentina)

open access: yesGeologica Acta, 2005
A new species of squid, Teudopsis jeletzkyi n. sp., is described from the Toarcian (Lower Jurassic) of the Los Molles Formation in Neuquen Province, central west Argentina. Fossil squids have thus far been unknown in the Mesozoic of South America.

The complete mitochondrial genomes of two vent squat lobsters, Munidopsis lauensis and M. verrilli: Novel gene arrangements and phylogenetic implications

open access: yesEcology and Evolution, Volume 9, Issue 22, Page 12390-12407, November 2019., 2019
The mitogenomes of M. lauensis and M. verrilli show novel arrangements of mitochondrial genes. Comparisons of mitochondrial gene rearrangements, to some extent, are a useful tool for phylogenetic studies. Abstract Hydrothermal vents are considered as one of the most extremely harsh environments on the Earth.

The Continuing Debate on Deep Molluscan Phylogeny: Evidence for Serialia (Mollusca, Monoplacophora + Polyplacophora)

open access: yesBioMed Research International, Volume 2013, Issue 1, 2013., 2013
Molluscs are a diverse animal phylum with a formidable fossil record. Although there is little doubt about the monophyly of the eight extant classes, relationships between these groups are controversial. We analysed a comprehensive multilocus molecular data set for molluscs, the first to include multiple species from all classes, including five ...

Transcriptome profiling of the posterior salivary glands of the cuttlefish Sepia officinalis from the Portuguese West coast

open access: yesFrontiers in Marine Science
Cephalopods like octopuses and cuttlefishes are known to secrete a ‘toxic saliva’ to inject into their prey, especially crustaceans since the XIX century.

Sentience in cephalopod molluscs: an updated assessment

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1311-1333, June 2026.
ABSTRACT This article evaluates the evidence for sentience – the capacity to have feelings – in cephalopod molluscs: octopus, cuttlefish, squid, and nautilus. Our framework includes eight criteria, covering both whether the animal's nervous system could support sentience and whether their behaviour indicates sentience.

Eocene belemnites from Hungary

open access: yesPapers in Palaeontology, Volume 12, Issue 2, March/April 2026.
Abstract The Middle Eocene nummulitic limestone at Dudar, Transdanubian Hungary, has yielded several belemnite rostra during the last 60–70 years. The correct interpretation of these fossils was made possible by the fact that one of these specimens retained the remnants of the conotheca within the alveolus, while others preserved the conical, tapering ...

Microstructural and geochemical evidence offers a solution to the cephalopod cameral deposits riddle

open access: yesPalaeontology, Volume 68, Issue 6, November/December 2025.
Abstract Orthoceratoid cephalopods are common in the Palaeozoic rock record but went extinct in the Late Triassic. Many orthoceratoids contain cameral deposits, which are enigmatic calcareous structures within their chambered shell that presumably balanced their straight conchs in a horizontal position. Since the mid‐19th century, palaeontologists have

Cephalopod Gastronomy—A Promise for the Future

open access: yesFrontiers in Communication, 2018
Cephalopods, specifically Coleoidea (squid, octopus, and cuttlefish), have for millennia been used as marine food by humans across the world and across different food cultures.

THE FIRST CENOZOIC OCTOPOD: A LOWER EOCENE RECORD FROM BOLCA, NORTHEASTERN ITALY

open access: yesRivista Italiana di Paleontologia e Stratigrafia
To date, soft-tissue remains of extinct incirrate octopods have been described exclusively from Upper Cretaceous deposits. Here, three specimens of an incirrate octopodid with well-preserved soft tissue imprints are described for the first time from ...
