2,000 people help reveal skeleton of giant predator older than dinosaurs

A huge fossilised skeleton weighing 1,300 kilograms (2,865 pounds) that was found in southern Poland is currently being chipped out of solid rock by a group of more than 2,000 public volunteers.According to a report by the Associated Press, this unusual public science project is happening inside a special glass-walled lab on the ground floor of Warsaw's Copernicus Science Centre. Museum visitors frequently stop on the other side of the glass wall to watch as volunteers wearing safety goggles use special tools to clean the fossil. Children point with excitement while parents look at the massive creature the bones once belonged to.The careful cleaning work needs great focus. Each bone must be cleared from the rock around it millimetre by millimetre using a small air-powered chisel.
