Fossil Opals

Opalised snail, shells, pipes and dinosaur for sale. Australia had a major inland sea millions of years ago. As part of that deposits of shells, Pipes (Ancient squids), Crynoids (Plant ferns) and Plesasouris and Dinosaur fell in to the sand of the sea.

Over the millions of years during the weathering process, opal replaced the fossils cavities that was left when the original item disolved. It is a thrill to mine these pieces as you know the orginal piece was millions of years old.
