“…4) and occurrence within non-hardground-type deposits (shell beds) indicate that the majority of the cobbles studied (especially those of smaller sizes) must have been transported, colonized by cementing biotas and periodically overturned. Thus, the cobbles have all the characteristics of a mobile rockground (e.g., Wilson, 1985Wilson, , 1987Bryan, 1992;Plint et al, 2006). Periodic overturning is not only evidenced by encrustation on all sides, but also in the abraded skeletons of the encrusters.…”

Bored and encrusted carbonate concretions, termed hiatus concretions, coming from the Middle Jurassic (Upper Bajocian and Bathonian) siliciclastics of the Polish Jura, south-central Poland, have been subjected to detailed paleoecological investigation for the first time. The concretions possess variable morphology and bear distinct traces of bioerosion and encrustation as a result of exhumation on the sea floor during intervals of low sedimentation and/or erosion. The borings are dominated by Gastrochaenolites and Entobia. Epilithozoans, represented by at least 26 taxa, are dominated by sabellid/serpulid worm tubes and bryozoans, while sponges and corals are minor. No relationship between the concretion size and the number of encrusters has been found, suggesting that concretion size was not the primary factor controlling diversity. Stable isotope analyses and the presence of crustacean scratch marks and Rhizocorallium traces on many of the hiatus concretions indicate that they formed just below the sediment-water interface, within the sulfate reduction zone. Moreover, crustacean activities may have been a prelude to their origin, as shapes of many concretions closely resemble thalassinoidean burrow systems. It is also possible that crustacean activity around the concretions promoted their exhumation by loosening the surrounding soft sediment. The presence of borings and encrusters on different concretion surfaces, as well as truncated borings and a number of abraded epilithozoans, indicate that after the concretions were exhumed they were repeatedly overturned and moved on the sea floor, probably due to episodic storm-related bottom currents in shallow subtidal environment.

“…Both neontologists and paleontologists have used the terms epibiont and epibiosis to describe the colonization of dead organic and inorganic substrates (see Taylor & Wilson, 2003 and references cited therein;Freeman et al, 2013;Schneider, 2013), as well as to refer to vagile organisms associated with a living organism (e.g., Ayres-Peres & Mantelatto, 2010;Fuller, et al 2010;Smyth & Roberts, 2010;Gordillo & Archuby, 2014). Some authors use the term epibiont to indicate invertebrates that live on rocks, pebbles or boulders (Plint et al, 2006;Chumakov et al, 2013;Powell et al, 2019).…”
