Kilek section, Kilek-24 (Triassic of Turkey)

Where: Turkey (36.9° N, 34.2° E: paleocoordinates 36.9° N, 34.2° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Tetraporobrachia haeckeli other zone, Huglu Tuffite Formation, Julian (235.0 - 232.0 Ma)

• The main part of the radiolarian fauna correlates well with faunas obtained from the upper Lower Carnian (based on the two-fold Carnian subdivison) or middle Middle Carnian (based on the three-fold Carnian subdivison), indicating the Tetraporobrachia haeckeli Zone in previous studies. Some of the taxa in sample Kilek-23 were previously obtained from the uppermost Lower Carnian (based on the two-fold Carnian subdivision) or the uppermost Middle Carnian strata (based on the three-fold subdivision), indicating the Elbistanium gracile Zone. Due to the presence of the index taxon for the Tetraporobrachia haeckeli Zone and the absence of the index taxon for the earlier Elbistanium gracile Zone, the radiolarian fauna from sample Kilek-23 corresponds to the Tetraporobrachia haeckeli Zone. Based on this radiolarian fauna, the age of the ostracod fauna retrieved from the subsequent sample (Kilek-24) can be assigned to late Early Carnian (based on the twofold Carnian subdivision) or middle Middle Carnian (based on the three-fold Carnian subdivision).
