Short summary
Sixteen samples contain one to six Ordovician trilobites preserved in the protected space inside of empty cephalopod conchs or under diverse parts of exoskeletons of much larger disarticulated trilobites. Analyses of the level of articulation of trilobites in combination with their orientation, disposition, and placement make it possible to conclude that the hidden trilobites deliberately entered shells of dead cephalopods for food, refuge, ecdysis, reproduction or lodging.
