66 million years ago, a fish chewed up and spit out food. It's now a fossil in Denmark

About 66 million years ago, a fish chewed up and spit out crinoid fragments, which were preserved in fossil form. The fossil was found at Stevns Klint, Denmark, and brought to the East Zealand Museum. This fossil provides new knowledge about predator-prey relationships in the Cretaceous sea. The fish likely spit out the crinoids due to their lack of nutrition and toxic mucus coating. The fossil is an example of regurgitalite, a type of fossilized vomit, and is one of several types of “trace fossils” found in the area.
