Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Taboulouart Fm, which unconformably overlies the Talmest Fm (Early Cretaceous), and is in turn overlain by the Bouzergoun Fm (Early Cretaceous). AGE: Late Barremian, on the basis of ammonite biostratigraphy; Toxancyloceras vandenheckii biozone. STRATIGRAPHIC POSITION: From bed 119, 31-32 m above base, near top of section.
