Abstract.
Echinoid bite traces on Late Cretaceous (early Maastrichtian) bourgueticrinids and isocrinids of southern Poland (Miechów Trough) were documented. The bitten sea lilies co-occurred with Goniopygus, a regular echinoid possessing an Aristotle's lantern. This is the first record of Goniopygus in the lower Maastrichtian of Poland. Considering former studies, as well as direct in situ observations of extant sea lilies and sea urchin behavior, the traces at hand could be most likely linked with predatory actions of the Goniopygus echinoid. Such studies on predatory phenomena are crucial and could provide baseline data concerning the evolutionary trends among organisms engaged in the “arms race”.
The comments of two reviewers, Andreas Kroh (Natural History Museum, Vienna, Austria) and an anonymous reviewer helped to improve the manuscript. Andreas Kroh (Natural History Museum, Vienna) is again thanked for help with the echinoid identification (Goniopygus). This project was partly supported by NCN grant no. DEC-2012/07/N/ST10/04103 and DEC-2015/17/N/ ST10/03069. The project has also been granted by the Leading National Research Centre (KNOW) to the Centre for Polar Studies for the period 2014–2018.
