The Sedgwick Museum of Earth Sciences is the oldest of the University of Cambridge museums, having been established in 1728 as the Woodwardian Museum. Since then the collection has grown from about 10,000 fossils, minerals and rocks, to at least 2 million. A walk through the museum will take you on a 4.5 billion year journey through time, from the meteoritic building blocks of planets, to the thousands of fossils of animals and plants that illustrate the evolution of life in the oceans, on land and in the air. Also a major teaching and research resource in the Department of Earth Sciences, the Sedgwick Museum collections are a national treasure.
