Where: Bouches-Du-Rhone, France (43.5° N, 5.5° E: paleocoordinates 43.3° N, 2.8° E)

• local area-level geographic resolution
When: Niveau du gypse d'Aix Formation, Chattian (28.1 - 23.0 Ma)
• "The ‘insect formation’ is 2.5 m thick, divided in two parts that correspond to two very different environmental conditions. The first (lower) episode is remarkable by its lateral mo- notony of facies on a distance of 6 km at least, in the outcrops observed on the northwest of Aix-en-Provence. This lower episode is distinguished from the rest of the ‘insect formation’ and from the whole formation of Aix-en-Provence by the presence of a very numerous thin limestone laminae. The second (upper) episode is remarkable by the presence of many silici- fied laminae. The fauna in this level is also very well preserved"….This collection consists of unspecified layers
