Earth Collections: Oligocene database

Oligocene fossils are quite thinly represented in the Museum's collections. This is due to a combination of factors - the Oligocene was a time of cooling climates and falling sea levels which reduced deposition and shelf habitats, and thus overall biomass and biodiversity - hence fewer fossils.
