This article is a taxonomic study of the radiolarian species of the
superfamilies Eptingiacea and Saturnaliacea occurring in the middle
Carnian fauna from the Koseyahya section, near the town of Elbistan,
southeastern Turkey. This fauna is characteristic of the
Tetraporobrachia haeckeli Radiolarian Zone as defined in Austria and
later found also in Turkey and Oman. It comes from an 8 m thick
succession of clayey/cherty limestones from the lower part of the
section. In addition, a few species from the late Ladinian and Carnian
from Oman and the early Norian from Alaska have also been included in
this study, in order to improve some generic diagnoses and to show the
diversity and evolutionary trends of some genera. 32 radiolarian species
of which 22 are new are described and illustrated, and assigned to 16
genera of which three are new (Capnuchospyris, Veleptingium, and
Triassolaguncula). The diagnoses of some species, genera, subfamilies
and families have been revised, and the family Eptingiidae has been
raised to the rank of superfamily.
