Locality Yo. 243A, Derik region (Ordovician of Turkey)

Where: Turkey (37.3° N, 49.5° E: paleocoordinates 29.5° S, 124.4° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Lagenochitina dalbyensis other zone, Lower Shale Member (Bedinan Formation), Caradoc (458.4 - 449.5 Ma)

• "The lowest fossiliferous horizon in the Bedinan Formation was found 0.5 m above its base at loc. Yo. 242... About 46 m higher in the succession, at loc. Yo. 243A, the fauna was more varied..." Chitinozoan zone based on Armoricochitina granulifera, which is common in the Lagenochitina dalbyensis zone.

Environment/lithology: offshore; poorly lithified, gray, green shale and lithified siltstone

• Environment not reported in text; inferred from lithology to be offshore [SMH]
• friable, green-gray shales with occasional thin beds siltstone
