George W. Hart (2000)
Webpage explaining a method for constructing images of icosahedral geometric structures is described. An example Artificial Radiolarian Reticulum illustrates the process. The algorithm was devised for producing images of sculptures too complex to realize by traditional means. From: George W. Hart, 2000. Reticulated Geodesic Constructions. Computers and Graphics, Vol 24 (6): 907-910.

INTERRAD-Mezosoic Radiolaria Database
This database contains the INTERRAD Jurassic-Cretaceous Working Group (1995) radiolarian database with the systematics, sample database, and the UAZ95 biochronology. It also includes the Middle Cretaceous radiolarian biochronology and palaeontology from Northern Apennines and Betic Cordillera by O’DOGHERTY (1994). The published portions of this database are accessible by submitting a request for an account, while the unpublished data sets are accessible via username/password to members of the working group with editing privileges.
Contains all the information required for the next INTERRAD meeting to be held in Lausanne, Switzerland, 2003.

Radiolarians and radiolarites
General presentation of radiolarians : what they are, how they contribute to the geological record. Subdivided in 4 main parts : 1- historical background, 2- Plankton, 3- Siliceous sediments and 4- rads in geological sequences. With plates, figures.

The database deals with radiolarian type specimens which were described from Japan and by Japanese researchers. Each datum is systematically arranged as follows: (1) Scientific name (Generic and specific name), Author name and year, (2)Name of publication, (3)Category of type specimen and registration number, (4)Sample and locality, (5)Name of Geologic bodies and (6)Geologic age.

The Micropalaeontological Society (TMS)
The Micropalaeontological Society is a multidisciplinary group with researchers in the fields of silicofossils (radiolarians, diatoms, sponge spicules, and silicoflagellates), foraminifera, nannofossils etc... The group organizes frequent meetings discussing a wide range of topics concerning microfossils.
The Rad Page
Fabrice Cordey's radiolarian homepage includes sections on Techniques of study, Overview of Cordilleran occurrences, Contribution to mining exploration, as well as other scientific results.


Micropaleontological Reference Centers (MRCs)
The scope of the MRC collections is global, with ca 5,000 prepared samples for each of the four fossil groups held (planktonic foraminifera, calcareous nannofossils, diatoms and radiolaria). The MRC collections closely reflect the overall pattern of recovery by the DSDP and ODP projects, which in turn reflect primary patterns of microfossil and sediment preservation through time.
The Ehrenberg Collection
Dave Lazarus has a web-page about Christian Gottfried Ehrenberg and the Ehrenberg Collection.
Type collection, Paleontological Museum in Oslo, Norway
Type collection at the Paleontological Museum in Oslo (Norway) contains several radiolarian specimens (light microscope slides) and articles about radiolarians. The easiest way to find radiolarians when searching the fossil database is to choose "Radiolaria" under "fossil group".
