Description
Laboratory palaeontology. Palaeontologists trying to reconstruct the skeleton of a plesiosaur from fossil remains. The pinkish colour of the 'bones' shows that they have been opalised - the original bone material replaced with opal (hydrous silicon oxide) to form the permanent fossil. The fossil is about 120 million years old, and was found at Coober Pedy in Australia. The plesiosaur was a marine carnivorous dinosaur which thrived in the mid to late Cretaceous Period. Photographed at the Sydney Museum, Australia.
