Images
The following images are of a representative selection of foraminifera aimed at giving a general overview of the different morphotypes. Each specimen is given a generic and, if possible, a species name followed by its age range, the site location from which the sample was obtained and its size in microns. LM (Light Microscope) SEM (Scanning Electron Microscope) TS (Thin Section). Typical and selected marker species are illustrated from each main period of the geological column in which foraminifera occur. Click on an image to view a larger version. Because Foraminifera formsuch a diverse taxon they have been split into three groups: planktics, benthics and larger benthics.
