Argiles et Grès à Reptiles Formation (meaning Reptile Clay and Sandstone) also known as the Argiles Rutilantes Formation[1] is an early Maastrichtian[2] French geologic formation in the département of Var preserving the remains of several types of dinosaurs and other extinct organisms.[3]

Fossil content

An abelisaurid similar to Arcovenator is known from Département des Bouches-du-Rhone, while enantiornithean and indeterminate avialan remains are known from Département du Var.[2]
