Summary
Compared to Mesozoic ammonoids, Mesozoic coleoids receive less attention from palaeontologists and biologists. This may be explained by the lower diversity and the lower amount of specimens. Remarkably, some anatomical details are more often preserved in coleoids than in ammonoids and thus, the anatomy of some coleoids is better known than that of the more common ammonoids. The more common exceptional preservation among coleoids makes them interesting study objects. Especially Fossillagerstaetten which yield fossilised non-mineralised organs of various organisms may yield coleoid remains with interesting anatomic details preserved. One important example is the Late Jurassic (Kimmeridgian) of Nusplingen (SW Germany). This locality is probably the only Jurassic locality worldwide which yielded complete beak apparatuses of all important cephalopod groups (ammonites, nautilids, belemnites and other coleoids).
Within this project, new and rare coleoid finds are described and discussed in their phylogenetic, anatomic and taphonomic framework.
