The Section Marine Evertebrates 3 of the Senckenberg Research Institute houses a wide-ranging collection of bryozoans from the North Sea, the Mediterranean, the Arabian seas. the East Asian coastal seas (Philippines, Japan, Hainan/China), the Southern Ocean (New Zealand, Australia), and Antarctica.
The collection has been significantly expanded by the donation of about 15,000 specimen boxes of Professor Heinrich Ristedt (Bonn, Germany). The Ristedt -Collection is composed of dried specimens, mounted on match boxes in small plastik containers. We have adopted this practical system to integrate all new collections.
The Senckenberg collection of fossil bryozoans is even larger, since Professor Voigt (Hamburg; 1905-2004) has left us with a massive legacy of the wordwide most comprehensive collection of Cretaceous bryozoans of irreplacable and inestimate scientific value.The lasting international importance is due to a complete documentation of Cretaceous to Paleocene Bryozoa, collected from the Carbonate Boreal Chalk Sea in northern and eastern Europe, covering the stratigraphical record from Cenomanian to Danian and thus the rise and fall of the respective carbonate platform, collapsing during the Paleocene Eocence Thermal Maximum (PETM).
The collection at the Senckenberg should contains 256 holoypes and neotypes. In the course of a collection management project funded by the German Research Foundation DFG (see below), the holotypes of 20 species could not be found and possibly have to be considered lost. Furthermore, there are 2,666 published Originals (75% of them now located with data available in the internet), and appr. 300,000 additional specimen series from Ordovician to Recent. The DFG supported thje documentation and digitalisation of the Voigt collection (Project SCHO 581/12-1) .
