“…Balanoglossites is a common constituent of shallow-marine carbonates, ranging throughout the Phanerozoic and occurring globally (Knaust, 2021b). It has often been confused with ichnospecies of Thalassinoides , from which it differs by its very irregular three-dimensional architecture and highly varying burrow diameter, as well as a predominance of U- and Y-shaped elements (Knaust, 2021c, 2024). Balanoglossites triadicus was produced mainly by polychaetes with a burrowing and partly bioeroding ability, which might also have been the case for the examples recorded from Rügen for the first time.…”

The lower Maastrichtian chalk of the Isle of Rügen was deposited in a pelagic setting in the aphotic zone. Its rich fossil content has attracted research attention for centuries, whereas its ichnological characteristics remain poorly understood, even though horizons with intense bioturbation and occurrences of trace fossils in flint are common. The enhanced colour contrast of smooth chalk faces reveals repeated phases of benthic colonisation; larger burrows are commonly subject to silicification, while flint nodules also can preserve burrows in chalk. A total of 37 ichnogenera, including 47 ichnospecies of bioturbation and bioerosion trace fossils have been recognised; these are here briefly described, in addition to indeterminate material. Many ichnotaxa are recorded for the first time from the Rügen chalk. Bioerosion is restricted mainly to local hardgrounds in the form of biogenic components (such as shells and belemnite guards).

“…It was originally described from Albian–Cenomanian chalk of south-east England; it is common in shallow-marine Cretaceous chalk deposits of north-west Europe. Based on finds of body fossils within the burrows and modern analogues, dwelling decapod crustaceans (foremost callianassid shrimp) were likely producers (Knaust, 2024).…”
