Short summary
We describe a biting trace on the oral surface of a large Maastrichtian holasteroid echinoid Echinocorys ovata from Hemmoor (northern Germany) which exhibits four circular punctures, arranged in a semi-circular arc. The punctures were not lethal to the sea urchin as is indicated by progressed skeletal regeneration and closure of the fractures. The shape and arrangement of the biting trace are analyzed suggesting that it was produced most likely by a globidensine mosasauroid.
