Triassic coleoid beaks and other structures from the Calcareous Alps revisited [PDF]
Acta Palaeontologica Polonica, 2022 We performed comprehensive study of seven Carnian, Late Triassic specimens of a coleoid cephalopod Phragmoteuthis bisinuata, on which Suess based his hypothesis on “beaks of P. bisinuata”. Using SEM/EDS, we found that “beaks of P.

‘Arm brains’ (axial nerves) of Jurassic coleoids and the evolution of coleoid neuroanatomy
Swiss Journal of Palaeontology, 2023 Although patchy, the fossil record of coleoids bears a wealth of information on their soft part anatomy. Here, we describe remains of the axial nerve cord from both decabrachian (Acanthoteuthis, Belemnotheutis, Chondroteuthis) and octobrachian ...

Distraction sinking and fossilized coleoid predatory behaviour from the German Early Jurassic
Swiss Journal of Palaeontology, 2021 Exceptional fossil preservation is required to conserve soft-bodied fossils and even more so to conserve their behaviour. Here, we describe a fossil of a co-occurrence of representatives of two different octobrachian coleoid species. The fossils are from

Swiss Journal of Palaeontology, 2021 Ammonoid soft parts have been rarely described. Here, we document the soft parts of a perisphinctid ammonite from the early Tithonian of Wintershof near Eichstätt (Germany). This exceptional preservation was enabled by the special depositional conditions

The geography of body size in cuttlefishes (Cephalopoda, Sepiidae)
Swiss Journal of Palaeontology, 2021 This study explores body size in sepiids (Cephalopoda, Sepiidae) on the interspecific scale and provides an overview of their geographical distribution. Results reveal a highly skewed distribution of body size variation for raw values and a nearly normal

Rivista Italiana di Paleontologia e Stratigrafia, 2022 The application of high-resolution X-ray computed tomography permits an appraisal of historically and newly collected specimens of Belosaepia (Belosaepiidae, Coleoidea, Cephalopoda) from the Ypresian (Early Eocene) of Belgium and provides resolution ...
