Where: South Khorasan, Iran (34.1° N, 58.1° E: paleocoordinates 14.8° S, 45.0° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Howz-e-Khan Member (Nayband Formation), Alaunian to Alaunian (215.6 - 201.3 Ma)

• Units A and B (lower ~8 m) probably as old as mid-Norian but upper part of section likely Rhaetian.

• These reef communities formed small-scale biostromes and in some cases, larger bioherms situated on shallow carbonate ramps at depths at or slightly below the wave base.
• Reef carbonates with micritic matrix, gray in color with boundstone, floatstone, and packstone microfacies

Size class: macrofossils

Preservation: recrystallized
