About Our Holdings
Foram Type Images
Catalogs and Information
Most groups of fossil protists and prokaryotes, geologic ages, and geographic
regions are represented in the UCMP collections. The holdings include
over 10,000 type specimens, tens of thousands of prepared specimens, innumerable
processed and bulk samples, and extensive reference materials.
Visitors can access microfossil collections data in two ways: via a small
catalog that contains images
of type specimens captured by us using our environmental scanning
electron microscope, or through an on-line database search of the catalog. Read below for more information on searching
the full microfossil catalog.
Fields & Searching
The full microfossil catalog contains searchable information on type
specimens, localities and citations.
The microfossil type collection contains specimens which were illustrated
or referred to in a publication as representative of a particular form
the author(s) studied. Primary types are the specimens chosen as
nameholders when a species or subspecies is first described. These include
the holotype (the primary nameholder of a species) and paratypes (specimens
also considered typical of the species and published in the original description).
Secondary types are specimens assigned to a species after the initial
description of that species, and include hypotypes and figured and unfigured
specimens (these latter two indicate specimens questionably assigned to
The taxonomic information was taken directly from the publications in
which these specimens were cited, and may not correspond to classifications
currently in use. The taxonomic information lists the original author
who described the species. Informal taxonomic group names are given for
ease in retrieving records of specimens of a particular group from a geographic
region or geologic time period. Group names currently in use are:
The citation information gives the publication in which the cataloged
specimen was cited. Locality data includes location and age..
