The Booth Museum houses collections of the geology found around Sussex.

This geological collection shows examples of the natural history of Sussex, Britain and the World for the past 4 billion years.

The fossils date from stromatolite fossils, some of the earliest oxygen breathing life forms over 3 billion years old. Sussex chalk collections dating from the age of the dinosaurs, and material from the elephant beds beneath Brighton, with ice age mammal fossils and subfossils.

The fossil collection also includes iguanodon dinosaur bones from Sussex. This was one of the first recognised dinosaurs and helped launch the field of palaeontology.

There are also large mineralogical and sedimentological specimens making up the remainder of the geology collections, as well as petrological slides in our microscopy section.
