A collection of more than 5,000 specimens of fossils, minerals and rocks has been donated to the University of Portsmouth.

The items include a plesiosaur thorax, Cretaceous and Jurassic starfish, giant shark and mammoth teeth, ammonites and even flint hand axes made by prehistoric man.

Some of the fossils date from the Proterozoic Eon when life was only in its infancy some 1,500 million years ago and have been donated by the widow of geologist Dr Paul Olver.
