The collections of A. E. Reuss were missing for a long period of time. When they were rediscovered they were stored in the Museum of Natural History in Vienna. The associated catalog is still missing. Since many of the Cretaceous foraminifers described by Reuss are assumed to be widespread around the world, it is desirable to have his original material as a reference when classifying the specimens found in drillings and natural exposures. As quite a lot of them are usable as index fossils, they are of special value in the exploration for oil and gas.
