Anatomy and evolution of the first Coleoidea in the Carboniferous. [PDF]
Commun Biol, 2019 AbstractColeoidea (squids and octopuses) comprise all crown group cephalopods except the Nautilida. Coleoids are characterized by internal shell (endocochleate), ink sac and arm hooks, while nautilids lack an ink sac, arm hooks, suckers, and have an external conch (ectocochleate).

Pterosaurs ate soft-bodied cephalopods (Coleoidea). [PDF]
Sci Rep, 2020 AbstractDirect evidence of successful or failed predation is rare in the fossil record but essential for reconstructing extinct food webs. Here, we report the first evidence of a failed predation attempt by a pterosaur on a soft-bodied coleoid cephalopod.

The Xiphoteuthididae Bather, 1892 (Aulacocerida, Coleoidea)
, 1999 Problems in the classification of the Xiphoteuthididae have been recently addressed (Mariotti and Pignatti, 1992, 1994, 1996; Pignatti and Mariotti, 1996), but a critical revision is still lacking, owing mainly to their incomplete fossil record. The following outline of a classification summarizes diagnostic characters, taxonomic relationships, and ...

Calcitic skeletons of recent and fossil Coleoidea
, 2017 Die calcitischen Rostren der Belemniten, einer ausgestorbenen Coeloideengruppe, sind häufig verwendete geochemische Archive. Trotz dieser weitverbreiteten Anwendung ist ihre Verwendung als Paläoumweltarchive umstritten. Untersuchungen dieser Arbeit zeigen, dass Belemnitendaten kritisch in einem sedimentologisch/paläontologischen Kontext interpretiert ...

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.
