205-million-year-old bone of prehistoric reptile discovered
A group of international palaeontologists have identified a 205-million-year-old jaw bone of a prehistoric reptile, said to be "one of the largest animals ever". Based on the fossil, researchers estimate the ichthyosaur was at least 20-25 metres long. The discovery also solved a 150-year-old mystery, when ichthyosaur fossils were misinterpreted as dinosaur bones.
