The Museum's diatom collection is one of the largest in the world, containing over 300,000 specimens accumulated from the early nineteenth century to the present day.

Strengths

The collections are a crucial resource for modern research, diatom specimens are used to answer scientific questions about areas as diverse as climate change and phylogenetic relationships.

The collections are extremely geographically and taxonomically diverse, containing representatives from freshwater, brackish and marine environments.

All major diatom groups, both fossil and recent, are represented.

The comprehensive assortment of fossil specimens, includes one of the best representations of Cretaceous diatoms.
