FOSSIL BELEMNITE SPECIMEN
COOBER PEDY
AUSTRALIA
BELEMNITES REMOVED FROM HOST ROCK THEN POLISHED AND PUT BACK ON HOST ROCK
This is a opalized fossil replacement of a marine creature "belemnite" that roamed the Cretaceous sea 100 million years ago. Very similar to our squid to day
Belemnites were marine animals belonging to the phylum Mollusca and the class Cephalopoda. ... In the animal's tail, the skeleton formed a bullet-shaped feature sometimes referred to as a guard, but more correctly termed a rostrum (plural: rostra).
