They became extinct at the end of the Cretaceous, around the same time as the dinosaurs. What remains is the rostrum: a bullet-shaped internal skeleton that fossilized as sediment hardened around it over millions of years. When opal replaces the original material, the result is one of nature's most extraordinary collectibles.
