Shine Dzhinsetu (Silurian of Mongolia)

Also known as Glassia minuta Community, Dzhinsetu Ula Range

Where: Mongolia (44.2° N, 99.9° E: paleocoordinates 30.2° N, 35.4° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Aeronian (440.8 - 438.5 Ma)

• lower part of Middle Llandovery. I therefore changed it to Aeronian (PJW)

Environment/lithology: marine; gray limestone and calcareous sandstone

• See lithology.
• "Occurs in gray limestones and fine-grained, dense, sandy, calcareous concretions (about 20cm diameter) in gray, fine-grained feldspathic sandstones. The brachiopods are articulated. The fine-grained, terrigenous sediment accumulated far from shoreline in what was a quiet water, BA4-5 environment (as in the Lithuanian Silurian)."

Size class: macrofossils
