The children have been learning about dinosaurs and how long ago they lived. As part of a week on 'How do we know about dinosaurs?' the children studied Mary Anning, the famous fossil hunter and then they had a visit from a modern palaleontologist. Alistair Bowden is Grace's uncle and he specialises in pre-historic marine life. He showed the children fossils of dinosaur footprints, ferns and egg shell and then he did an activity to show how we can find out information about dinosaurs just from their footprints.
