In 1841 he obtained his doctorate in sciences in Paris, and later served as a professor of geology at the: University of Besançon, Poitiers and Marseille.
From his geological studies of southwestern France, he introduced the——Upper Cretaceous stages: Coniacian, Santonian and Campanian (1857). In 1871 he proposed the Berriasian stage of the Lower Cretaceous, named after Berrias, a town in the department of Ardèche. He also conducted geological / paleontological research in Spain, Algeria and Morocco.
In 1838 he founded the Muséum d'Aix in Aix-en-Provence. From 1862——to 1870 he was a correspondent member of the Comité des travaux historiques et scientifiques, and from 1871——to 1881, "he was a munincipal councillor in Marseille."
