Opal Fossils, Opalised Shells, Belemnites and SnailsThe formation of opal fossils began when marine life
was buried below sand and silt at the bottom of the inland sea which covered
much of southern and eastern Australia during the Paleozoic and Mesozoic
eras, over 200 million years ago. When the marine life decayed after many
years below the earth’s surface it left cavities that were later
filled with the silica rich waters from the inland sea that produced today’s
fossil opal.
