The fossil bone (right) is the right humerus of a turtle from the Chatham Islands. The shell (centre) is a cast made by pouring plaster of Paris into an imprint formed by the shell of the bivalve mollusc Inoceramus galoi found near Kāwhia Harbour. The worm-like impression (top left) is called a trace fossil, as it shows traces left by a worm burrowing through mud.
These fossils are part of the GNS Science National Paleontological Collection.
