Short summary
Here, we describe an enigmatic new microfossil that was found encrusting a belemnite from the Middle Jurassic of the Falaises des Vaches Noires in Normandy, France. The organism has produced a conspicuous attachment etching on the belemnite for better adhesion and this trace fossil is new to science as well. Based on morphological criteria and the capacity to bioerode, the new microproblematicum can best be compared to encrusting bryozoans and foraminiferans.
