This site aims ultimately to provide an extensive guide to Radiolarian taxonomy. It will consist of two parts - a catalog of all described species and a parallel database with detailed information on accepted taxa.

Content at present (Nov 2019)

It is intended to significantly develop the site but at present it consists of two main parts:
  1. Catalog - this contains basic taxonomic references to ca 7,500 polycystine radiolarian taxa (6500 species, 1000 genera and above) described from the Cenozoic. It includes type images from the Suzuki database and descriptions from the Caulet database. Taxa are listed alphabetically under the name used in the publication they were described in.
  2. Main database - this is currently simply a listing of ca 2,500 radiolarian taxa (1,500 species, 1000 genera and above) used in DSDP and ODP reports as compiled for the Neptune database and considered valid on a basic taxonomic review (including elimination of many synonyms), as summarised in Lazarus et al. (2015). The taxa are organised by conventional families and then by new fimies as developed by Suzuki and co-workers. These taxa are linked to the catalog entries. This thus at present essentially provides an alternative way of browsing the content but it is intended to provide additional images, discussion of taxa, generic diagnoses etc.
    Linkage to the Neptune database allows display of occurrence data from the database, including occurrence frequency plots on each page and links to tools to plot occurrences on palaeobiogeographic maps and to see occurrence tables for individual sites.

People involved and data sources

Development of the site is being lead by David Lazarus (Museum für Naturkunde, Berlin). Data on the site is ultimately derived from the literature and so from the works of generations of plankton biologists and micropalaeontologists, from Ehrenberg to the present day. More recently this taxonomic data has been compiled and synthesised in several very large databasing projects, as outlined below. Here we are combining data and images on Cenozoic and living radiolaria from these systems and presenting it using a web content management system - mikrotax. The Mikrotax system was developed by Jeremy Young (University College London) who is assisting with data migration and database customisation. Data sources:

We believe that by synthesising data from these sources we will be able to build a single, universally accessible, database with a very large amount of useful reference data on radiolarian taxonomy. This will also provide a platform to incorporate modern images and document current species concepts. This has already been achieved for coccolithophores and planktonic foraminifera, reaching a similar level of coverage for radiolaria will be long-term project but will be achievable especially if a range of workers contribute to the project. Our current aim is to integrate a large body of content into a prototype website in time for the 2020 InterRad conference in Slovenia. radstrip
