We had great fun this morning, finding out about old fossils. (Respectful comments only please!)
Mold fossils – where something has landed and sediment has shaped around it, like the playdough on Mr Thomas’s nose (!) and the Lego brick under the plaster.
Cast fossils – the infill, once the animal is gone.
Trace fossils – showing where plant life had been… the leaf will leave one on the plaster.
Trace Form fossils – where an animal has left its mark… footprints and trails for instance.Subscribe to our blogs
