Microfossils are an immensely important component of ancient and Recent marine sediments. They not only contribute to large volumes of the sedimentary cover of the Earth's surface, but also tell us in most detailed manner the history of past global climates, environmental conditions, evolutionary processes, and plate tectonic changes. In order to decipher such fundamental information from (micro)fossils it is necessary to describe these species, their differences, and variations in the most complete manner and to illustrate them adequately. This is especially true if new species are discovered and holotypes are designated (a holotype is a particular specimen that represents the original author's concept for the species). Holotypes are indispensable to taxonomy as they form the basis to any biological or paleontological classification. Similar to scientific libraries, where literature and data are kept for reference purposes, holotypes are usually kept and curated in museum collections. In the case of microfossils, such holotypic materials can, in principle, be loaned to researchers for reasons of comparison with their own findings. However, any transfer of such materials runs the risk of damage or loss, with the consequence that a species concept might loose its formal existence. Such risks can be minimized if there were virtual representations of holotype (and other type) specimens, for example over the internet, where they can be seen from any location in the world in three dimensions and from all sides without removing the original from its safe place. Towards this goal the present article describes a method to illustrate microfossils seen in the light microscope in three dimensions on the internet by combination of focal depth enhancement, stereo-microphotography, and virtual reality techniques. For this purpose, a simple universal specimen stage was constructed, that allows to position a microfossil in almost any orientation under the binocular. The method is well-suited to illustrate microfossils in the size range between 100-1000 Ám, and is useful for teaching purposes, construction of virtual type-specimen atlases on the internet, and for the display of microfossils to a general audience in museum exhibitions.
