When they died, their hard internal rostrums (the bullet-shaped guard) were buried in sediment and, over millions of years, replaced by precious opal. The result is one of nature's most extraordinary fossils: a genuine prehistoric creature preserved in gemstone.\u003c\/p\u003e\u003cp\u003eThese specimens are highly sought after by opal collectors, fossil enthusiasts, and jewellers alike.
