The Museum has enormous collections of fossil and recent ostracods, including 20,000 single specimen mounts and many faunal slides.
Just over half of the collection is from the United Kingdom, but it also includes material from across the globe.
The collection covers the entire geological history of the Ostracoda from the Ordovician to the Recent. Particular strengths are in the Carboniferous, Jurassic, Cretaceous and Eocene.
The type and figured collection and associated slides have been arranged stratigraphically with individual named slides and assemblage slides kept together.
The Hull University Collection, former British Petroleum Microfossil Collection and former Aberystwyth Micropalaeontological Collection are kept separate from the main type and figured ostracod collection.
Major donors to the ostracod collections include:
