Turonian Radiolarians from Karnezeika, Argolis Peninsula, Peloponnesus (Greece) -- Radiolarian Correlation of Jurassic Siliceous Successions of the Rosso Ammonitico Formation in the Southern Alps and Western Sicily (Italy) -- Upper Jurassic Radiolaria from the Vocontian basin of SE France -- The plankton turnover at the Permo-Triassic boundary, emphasis on radiolarians -- An online micropaleontology database: Radiolaria.org -- A new genus of Entactiniidae (Radiolaria) from the Upper Permian of South China -- Radiolarian faunal turnover through the Paleocene-eocene transition, Mead Stream, New Zealand -- Upper Permian to Middle Jurassic radiolarian assemblages of Busuanga and surrounding islands, Palawan, Philippines -- Influence of the Frasnian-Famennian event on radiolarian faunas -- Middle to Upper Permian radiolarian faunas from chert blocks in Pai area, northwestern Thailand. Radiolaria are a very diverse marine siliceous microplankton group that have existed at least snice the Cambrian to the recent. This volume gives a representative view of research topics discussed at the 10th International Meeting of Radiolarian Palaeontologists. The articles of this volume cover mainly radiolarian biochronology and radiolarian fauna changes.
