Шаблон:Infobox rockunit 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.[1][2] The lithology consists of coarse sandstones with occasional conglomerates and mudstones.[3] Dinosaur remains are among the fossils that have been recovered from the formation.[4]

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.

Vertebrate paleofauna

The Ain el Guettar Formation during the Early Cretaceous period was a marsh-like habitat with swamps and plenty of water. The most famous dinosaur discoveries made here include Carcharodontosaurus and Spinosaurus.
