Imagine this: an amateur fossil hunter stumbles upon a peculiar find on a beach in Denmark. Peter Bennicke spotted something unusual in a piece of chalk at Stevns Klint—a cluster of lily pieces, all jumbled together. He brought his discovery to Geomuseum Faxe, where experts took a closer look.

John Jagt, a lily specialist from the Netherlands, examined the fossil. He found that it contained at least two species of lily, mashed into a round lump. This, he explained, is likely the indigestible parts of the lilies that were thrown up by an animal after eating them. Scientists call this type of fossil "regurgitalite. "

Why is this find so special? Well, regurgitalites offer valuable clues about ancient ecosystems. They tell us which creatures were eating whom. Jesper Milàn, a curator at Geomuseum Faxe, said that lilies aren't very nutritious because they're mostly made of calcium plates and few soft tissues. Yet, some animal—probably a fish—chowed down on these seabed plants and then upchucked the hard parts.

This discovery sheds light on the complex relationships between predators and prey in the Cretaceous seas, which existed around 66 million years ago. It's like a tiny puzzle piece that helps us understand the bigger picture of ancient marine life.
