The Sedgwick Museum takes its name from Adam Sedgwick, one of the founders of modern geology. It’s one of the world’s oldest geological museums and its collection comprises many millions of objects including spectacular ichthyosaurs found by the fossil collector Mary Anning. The fossils found in the Barrington Beds by a group of Cambridge geologists are on permanent display to the public. Among the exhibits are remains of hippo, red deer, hyena and elephant - as well as bear and bison. Look carefully at the stone used to sculpt the animals at the museum entrance and you will see that it’s full of tiny fragments of shells. The stone that Jackson chose for the ornamentation or dressings of the building is shelly oolitic limestone of Middle Jurassic age. This stone dates from around 170 million years ago, when marine animals flourished in the warm seas that covered much of the northern hemisphere.
