A 66 million-year-old fossilized piece of vomit, discovered in Denmark, has provided unique insights into the prehistoric food chain during the Cretaceous period when dinosaurs roamed the Earth. Local fossil hunter Peter Bennicke found the unusual fragments in chalk at Stevns Klint, a UNESCO-listed coastal cliff. The fossils were later confirmed to be sea lily pieces that would have been difficult for fish and sharks to digest, leading them to “regurgitate” the chalk bits. This rare find offers a glimpse into the daily life of ancient marine ecosystems, highlighting the complex relationships within the food chain 66 million years ago.
