Where: Jordan (32.2° N, 35.6° E: paleocoordinates 10.8° N, 30.4° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Mughanniyya Formation, Callovian (166.1 - 163.5 Ma)

Environment/lithology: deep subtidal; carbonate and siliciclastic

• the dominance of pennular corals with fenestrate septa suggest a comparatively deep environment well below fair weather wave base
• carbonate to siliciclastic rock sequence

Size class: macrofossils

Preservation: recrystallized, original aragonite, replaced with calcite

Collected by F. Ahmad

• material has been deposited in the collections of the Institut für Paläontologie der Universität Würzburg
