This article is a continuation of the taxonomic study of the exquisitely preserved
and extremely rich Late Carnian (early Tuvalian, Spongotortilispinus moixi Zone) radiolarian
fauna of the sample G 11 from the Sorgun Ophiolitic Melange occurring in the Tavuscayiri
block, Pindos-Hulu series, Tauride ophiolite belt, Turkey. 26 species of Spumellaria
with spongy test, belonging to 7 genera, are discussed and illustrated. Among them
14 species and two genera (Staurotortilispinus n. gen and Ancoraspongus n. gen) are
introduced as new. The assemblage provides new data on the diversity of the radiolarian
fauna of the Tethys during the Late Carnian and contributes to a better understanding
of the Mesozoic geodynamic evolution of the Mediterranean region.
