Abstrakt

A single example of a rosette-shaped embedment structure on the carina of a scalpellid cirripede (Bosquet Collection) from the basal portion of the Valkenburg Member (Maastricht Formation) at St Pietersberg (Maastricht, southern Limburg, The Netherlands) is described as a new ichnogenus and species, Flosculichnus tectus. It differs from other rosetted traces in calcareous hard substrates, which consist of slender, radiating borings, in having a scalloped, cyclic structure surrounding a central depression. The most probable producing organisms are either an unidentified, sessile, unmineralised invertebrate or, perhaps more likely, a scalpellid cirripede.
