The recent study, in the uppermost Barremian of La Bédoule (Bouches du Rhône -France) of a rich Pseudocrioceras level, (unambiguously équivalent of the Busnardo Pseudocrioceras coquandi Zone -1984) allowed us to precise the exact stratigraphical position of this genus, at the top of the Martelites sarasini Zone and in the immediately underlying beds of the Barrcmian/Aptian boundary, defined by the FAD of the first Deshayesites of the Deshayesites tuarkyricus Zone (Delanoy et alii, 1997 Ropolo et alii, 1999, Ropolo et alii -Gonnet el alii, in press). New investigations, led us to discover three new species of Ancyloceratidae : Gill, 1871 : Pseudocrioceras massei nov. sp., Pseudocrioceras rawsoni nov. sp. et Pseudocrioceras mickali nov. sp.. ...
