A mining engineer sets off an explosive charge deep inside a mine. The explosives dislodge large pieces of rock from the working face of the mine. When the dust has settled, these rocks are removed and checked for fossil remains. Dinosaur Cove is the world's first mine developed specifically for paleontology, normally the scientists rely on commercial mining to make the excavations. The site is of particular interest as the fossils found date from about 100 million years ago, when Australia was much closer to the South Pole than today. .
