Once upon a time, a fish had an upset tummy and puked its guts out. Sixty-six million years later, that puke is now available for the world to see.
According to the BBC, a Danish man discovered a strange-looking rock that turned out to be fossilized fish vomit from the Cretaceous period. The finding was confirmed by Denmark’s Museum of East Zealand.
While certainly gross, and perhaps embarrassing for the fish who threw up, the barf fossil is quite scientifically significant.
“It tells us something about who was eating who 66 million years ago,” paleontologist and museum curator Jesper Milan tells the BBC. “This find is a unique glimpse into the everyday situation in the bottom of the Cretaceous sea – the sea during which the dinosaurs lived.”
Milan adds, “This is the world’s most famous piece of puke ever.”
