The St. Laurent de Trier site is actually located on what is called a witness mound. During the Jurassic period the limestones of the causse were formed, and during the Upper Jurassic the dolomitic limestones were deposited. During this same period, between -190 MA and -140 MA, many reptiles left their footprints, including dinosaurs.
