Description
The Nagoya University Museum (NUM) has been a major research institution of radiolarian fossils since 1979, and the specimens have been actively collected and stored in the museum. NUM employed hierarchical repository system to manage a large amount of data of radiolarian species since then. The specimens were arranged and fixed on a stub, the stubs were preserved in a plastic case, and the plastic cases were stored in four cabinets in the storeroom. Details of each specimen, including the rock-samples in the storeroom, the locality map, and the Scanning Electron Microscope (SEM) image, are accessible from online-database system. This paper aims to check the user-friendliness for the database-system and the adequacy of storage-system of NUM radiolarian fossil collections. By using fossils of five representative species in the NUM collections, i.e., Unuma echinatus, Parvicingula mashitaensis, Pantanellium foveatum, Eucyrtidiellum semifactum, and Xitus gifuensis, it was found that the repository system worked properly to find out a particular fossil specimen from a large number of collections is very helpful for re-examination. If we had not prepared this repository system, it would be very laborious work to find a particular fossil body of the radiolarians from the thousands and thousands of tiny particles in the museum building. We have confirmed that the preservation method of the fossils in a plastic case, which has been stored within a cabinet, was actually effective enough for dust-proof and thus valid for re-studying the specimens in NUM.
