The Discovery of Dinosaur Cove
These volunteers and many others created this tunnel by first drilling and blasting out the rock above the fossil layer to create a space to stand in. Once that was done, they dug down in the floor to reach the fossiliferous layer using somewhat gentler means, i.e. hack hammers rather than explosives. For every 1 kg of fossiliferous rock recovered, 30 kg of overburden had to be removed. If no fossils were evident underground, the fossiliferous rock was carried outside into the sunlight where other volunteers broke up every rock with hammers and chisels looking for specimens. Far more fossils were first seen outside than underground. Photographer: Frank Coffa
