whelk fossil

Lightning Ridge, Australia

exceptionally rare and beautiful specimen.

A whelk is a type of marine gastropod mollusc (similar to a sea snail) with a spiral shell.

• These creatures lived in ancient seas and are commonly fossilised in limestone or sedimentary rocks globally.

• At Lightning Ridge, however, the fossilisation is unlike anywhere else...

Lightning Ridge in New South Wales is world-famous for precious black opal and a smaller number of opalised fossils, including:

• Marine invertebrates like whelks

• Bivalves, ammonites, and belemnites

• Occasionally, even vertebrates like turtles and dinosaurs
