Named for Chenini

The Chenini Member is a geological member of the Aïn el Guettar 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]

Vertebrate paleofauna

The Chenini Member 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.
