Atlas Maastrichtian Foraminifera
Integration of images of benthic species
Since December 2011 a project team consisting of Karl-Otto Bock, Michael Hesemann, Dieter Ketelsen and Stefan Raveling has worked on Maastrichtian Foraminifera from Northern Germany. Samples from the chalk-quarry Lägerdorf Grube Saturn and drill cores from Hemmoor and the Baltic Sea off Rügen were processed and about 230 SEM and optical images made.
In September 2012 Dr. Peter Frenzel, Friedrich Schiller University of Jena, Institute of Earth Sciences - an expert on Maastrichtian Foraminifera - joined the team and proposed the idea to build an Atlas of Boreal Maastrichtian Foraminifera through The team agreed. In 2013 all 501 images and illustrations from his publication were added: Frenzel, P. (2000): Die benthischen Foraminiferen der Rügener Schreibkreide (Unter-Maastrichtium, NE-Deutschland) [The benthic Foraminifera of the Rügen Chalk (Lower Maastrichtian, Northeastern Germany)]. Neue Paläontologische Abhandlungen, 3: 361 pp., 107 figs., 8 Tab, 46 plts.; Dresden.
It is planned to add images of species from other sources, such as the publications of the Grzybowski foundation on agglutinates.
Integration of images of planktonic species
In December 2013 Dr. Marcelle K. BouDagher-Fadel, University College London gave permission to use all images from her publications, such as Boudagher-Fadel, MK; (2013) Biostratigraphic and Geological Significance of Planktonic Foraminifera. (2nd ed.), London. The Smithsonian Institution National Museum of Natural History in Washington granted the usage of all of their images. We are in the process of adding the so far missing planktonic foraminiferal species. It is under consideration to add species, which lived in the Maastrichtian, though the images are from specimens of different stages.

Species Pages and Key to species
For the benthic species we created species pages with a synonym list and description of main morphological characteristics (Example: Alabamina dorsoplana (Brotzen, 1940)) These characteristics are also used in the key to species interface.
