Abstract
    The main interest of the otoliths collected in the Palaeocanyon of Saubrigues lies in the fact that a succession of five fish faunas from a significantly deeper environment than other places in the Aquitaine Basin can be studied there, in the same geographic area and in a sedimentary environment that remains almost constant throughout the considered time interval. A total of 170 taxa among which 109 nominal species have been identified from sediments filling the paleocanyon. Eight species are new: Halosaurus orthensis, "genus Gonostomatidarum" hoffmani, Polyipnus latus, Vinciguerria angulosa, Vinciguerria brevis, Merluccius abreviatus, Peristedion jeanbegui and Parascombrops epigonoides. The succession of fish biota in the paleocanyon is characterized by a major faunal break at the Chattian-Aquitanian boundary. Nineteen (= 45 %) of the 42 Chattian species disappear, and among the 23 species that cross the boundary, seven also disappear before the beginning of the late Burdigalian. At the beginning of the Aquitanian, a major faunal renovation is observed: 16 species appear in the palaeocanyon, which represent 59 % of a total of 27 Aquitanian species. In the succeeding levels from Early Burdigalian till Langhian, a gradual appearance of the typical Miocene fauna is observed.
