The National Museum of Natural History serves as the largest repository in the world of foraminiferal type specimens with over 16,000 primary type specimens (holotypes and paratypes), searchable on-line many with graphics, and over 200,000 secondary type specimens. It represents probably three-fourths of all the type specimens of the American smaller foraminifera, nine-tenths of those of the American Mesozoic and Cenozoic larger foraminifera, and a very large proportion of species from abroad that have been described in this country.
Other microfossil collections associated with the Cushman Collection include radiolaria, thecamoebians, and chitinozoa. Information about these specimens and some SEM images are available through the Online Catalog.
