Over the course of many years, paleontologists have unearthed fossils of creatures that were interacting at the time of their death—one such type of interaction involves a predator capturing prey. Prior researchers have called fossils of creatures just prior to being consumed "pabulites" (Latin for "leftovers.") In this new effort, the researchers studied an ancient crustacean pabulite that was about to be consumed by an ancient squid-like creature called a belemnite.

After careful study of the positioning of the two fossils, the researchers concluded that the belemnite was in the process of biting the crustacean, or perhaps the skin it was shedding. And while it was doing so, the belemnite was itself bitten by a larger predator—possibly an ancient shark. The bite, it turned out, was lethal. The belemnite, with the crustacean skin still in its mouth, sank to the bottom of the sea and died.
