Also known as Nitikin Locality 135
Where: Kazakhstan (44.7° N, 75.3° E: paleocoordinates 14.9° S, 74.9° E)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Climacograptus caudatus - Climacograptus morrisi graptolite zone, Degeres Member (Dulankara Formation), Katian (453.0 - 445.2 Ma)
• Dulankara Stage. Popov & Cocks (2006: txt. f. 3) show that this is the Degeres member.
