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 …

Although hyaline cartilage is widely distributed in various invertebrate groups such as
sabellid polychaetes, molluscs (cephalopods, gastropods) and a chelicerate arthropod …

Fossil oral ejecta that exclusively contain bivalved calcitic lower jaws of ammonites (=
aptychi) from Late Jurassic Solnhofen-type deposits of southern Germany are described …

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

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 …

Especially in Lagerstätten with exceptionally preserved fossils, we can sometimes recognize
fossilized remains of meals of animals. We suggest the term leftover fall for the event and the …

Carbonate hardparts of marine organisms are frequently explored archives of their ambient
seawater composition. Among the various materials used, the hardparts of molluscs are …

Ammonite soft body remains are rarely preserved. One of the biggest enigmas is the
morphology of the ammonite brachial crown that has, up till now, never been recovered …

Belemnite rostra are very abundant in Mesozoic marine deposits in many regions. Despite
this abundance, soft-tissue specimens of belemnites informing about anatomy and …
