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 …

Heteromorphs are ammonoids forming a conch with detached whorls (open coiling) or non‐
planispiral coiling. Such aberrant forms appeared convergently four times within this extinct …

Regeneration, a process consisting in regrowth of damaged structures and their functional
recovery, is widespread in several phyla of the animal kingdom from lower invertebrates to …

The taphonomic mechanisms of a mono-to pauci-specific ammonoid fauna comprising 3565
specimens from the lower Carnian Polzberg Konservat-Lagerstätte near Lunz am See …

Owing to their great diversity and abundance, ammonites and belemnites represented key
elements in Mesozoic food webs. Because of their extreme ontogenetic size increase by up …

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

Here we report new data on the Upper Triassic Polzberg Konservat-Lagerstätte in the
Northern Calcarous Alps of Lower Austria. We examined new fossil material obtained from …

A remarkable specimen of the actinopterygian fish Pachycormus macropterus from the Early
Jurassic (Toarcian) Posidonienschiefer Formation of Germany exceptionally preserves an …

A major goal in evolutionary biology is to characterize and understand the patterns and
processes that shape the evolutionary trajectory of clades through time and space. One …

Theoretical 3D models were digitally reconstructed from a phragmocone section of Baculites
compressus in order to investigate the hydrostatic properties of the orthoconic morphotype …
