Résumé

A stratigraphic study was carried out on the Jebel Boulahouajeb section (Lansarine Chain; Tebourba area, northern Tunisia) in order to establish a relatively detailed biostratigraphic framework of the Hauterivian pelagic deposits of the Tunisian trough. The limestone-marl alternations are represented by five limestone-dominated intervals, named calcareous bundles H1 to H5, separated by thick marly-dominated intervals. The well exposed Jebel Boulahouajeb section (873 m in thickness) is relatively continuous, rich in ammonoid macrofauna, and provides an ideal succession for this approach. Concerning the Hauterivian ammonoid zonal scheme, the following (sub-)zones have been identified: Acanthodiscus radiatus, Crioceratites loryi, Lyticoceras nodosoplicatum, Balearites balearis (with B.
