ABSTRACT
A waterblasting technique is introduced as a cleaning agent in fossil preparation. The pressurized water even leaves fragile skeletal fossils undamaged. Because the technique leaves the fossils in their original position within outcrop surfaces and samples, the technique is readily applicable for biofabric studies. Combined with the acid-hot water method, the waterblasting technique has been employed effectively in preparation of Campanian brachiopods and Maastrichtian bivalves and bryozoans as well as Danian octocorals, asteroids and regular echinoids.
