Children in Years 4 and 7 became fossil detectives and dinosaur hunters at the Rocks & Fossils workshop today. They had the chance to handle fossils believed to be 500 million years old. Dr Helen from Palaeoquest eagerly shared her huge collection of rocks and fossils with the children and told them how fossils were formed. The range of rocks was amazing, from Obsidian to Fools Gold. All agreed it was a wonderful, hands-on experience.
