Turkestan Mountains, Isfara River (Silurian of Tajikistan)

Also known as Reef 2518

Where: Tajikistan (39.9° N, 70.4° E: paleocoordinates 15.0° S, 75.4° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Pschemack Formation, Wenlock (433.4 - 427.4 Ma)

• PJW: Given as Merishkor, but that is the local stage equivalent of Wenlock. Given that it's limestone, it is probably the Pschemack formation rather than the largely siltstone Chorkuin formation.

• group of beds-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; lithified limestone

Size class: macrofossils

Collection methods: peel or thin section,
