Where: Bulgaria (42.6° N, 23.0° E)
• Paleocoordinates: 7.7° N, 36.1° E (Wright 2013)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Radomir Formation, Ladinian (241.5 - 237.0 Ma)
• Ladian brachiopod assemblages are geographically restricted and isolated from one another, which makes biostratigraphic correlation difficult. Within the Costispiriferina bittneri - Lima cf inaequistriata Assemblage Zone
• group of beds-level stratigraphic resolution
Environment/lithology: shallow subtidal; limestone
Size class: macrofossils
