Janosi-puszta, Mecsek Mts., Hungary (Cretaceous of Hungary)

Also known as Reef 1144

Where: Hungary (46.2° N, 18.3° E: paleocoordinates 28.6° N, 24.7° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Magyaregregy Conglomerate Formation, Valanginian (139.8 - 132.9 Ma)

• Local section: Korhadtfas ravine. Valanginian age based on rudists. Some gastropods and corals suggest section ranges up to early Aptian. Age now confirmed to be Valanginian (most probably early Valanginian) according to Bujtor pers. comm. 2006

• formation-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; lithified sandstone and lithified conglomerate

• Atoll setting
• Alternation of sandstone and conglomerate beds. Sandstone with carbonate cement and sphaeroidal weathering pattern.

Size class: macrofossils
