AbstractThe Berriasian — lower Valanginian genus Leptoceras reappears in the lower Barremian sequences of Rumania, where it is represented by at least two species: L. brunneriforme sp. nov. and L. svinitense sp. nov. This record has led to a revision of the so far accepted taxonomic interpretation of the criomorph Barremian Leptoceratoidinae and of their relationship with the Berriasian-Valanginian Protancyloceratinae. In addition, a new species of the genus Hamulinites (H. nicklesi, from the uppermost Hauterivian) provides evidence that the genus Eoleptoceras Manolov should be considered valid.
