CLAM SHELL

COOBER PEDY, SOUTH AUSTRALIA

OPALISED FOSSIL

GOOD COLOR

  • These are ancient marine shells (bivalves) that have been replaced by opal over millions of years.

  • The original shell material dissolves and is replaced by silica, preserving the shell’s shape and details.

  • They often come from the Early Cretaceous inland sea that once covered parts of SA.
