The Aïn el Guettar Formation is a geological formation in Tunisia, whose strata date back to the Late Aptian to Early Albian stages of the Cretaceous period. The lithology consists of coarse sandstones with occasional conglomerates and mudstones. Dinosaur remains are among the fossils that have been recovered from the formation.

Stratigraphy

The Aïn el Guettar Formation is divided into at least 3 members, which represent different depositional environments. In ascending order these are: the Chenini Member, the Oum ed Diab Member and the Jebel El Mra Member.
