| Thirty seven species and subspecies of ammonites of the families Ancyloceratidae Gill, 1871, and Heteroceratidae Spath, 1922, are described. The following new taxa are described; Crioceratites (Paracrioceras) leyvaensis, C. (P.) royogomezi, C. (P.) cabreraensis, Pedioceras multicostatum, Pseudocrioceras guanense, Kutatissites creutzbergi, K. densecostatus compactus, K. etayosernai, K. grandis, K.? galanensis, Ammonitoceras galanense, A. giganteum, Hamiticeras ventrotuberculatum, H. longum, Hemihoplites (Matheronites) ridzewskyi sachicaensis, Colchidites riosuarezi, C. pseudovulanensis, C. guanensis and C. striatosulcatus. Moreover, one new genus, Laqueoceras gen. nov., with the type species L. laqueus sp. nov., is proposed. |

| This paper deals with the ammonite biostratigraphy of the lower 312 m of the Miravetes Formation (sections Y and Z) exposed 500 m north and northwest of Los Miravetes along the Río Argos, 3 km west of Caravaca (SE Spain). This sequence embraces the uppermost Tithonian, Berriasian, and lower Valanginian. The succession of ammonite assemblages is similar to the one described by Le Hégarat (1971) from SE France. Le Hégarat's results are, where possible, completed and, where necessary, corrected. Arguments are adduced for a stratigraphic position of the Tithonian-Berriasian boundary, which should also be the Jurassic-Cretaceous boundary, between the Pseudosubplanites grandis and Subthurmannia (Strambergella) subalpina subzones. The Berriasian was divided into... |

| The Working Group proposes only one modification to its current zonation of the Mediterranean Region, the addition of a cristatum Subzone in the lower part of the inflatum Zone (upper Albian). But in the light of newly published research it highlights levels/areas where further work is required, especially to resolve conflicting zonal schemes. It also proposes a 'Tethyan Province' zonation for the middle Albian. Alternative correlations for the Boreal/Tethyan Valanginian to Barremian stages are tabulated, one based on ammonite evidence alone, the other with additional biostratigraphical data coupled with sequence stratigraphy and magnetostratigraphy. |

| On the basis of new and published palaeontological and stratigraphical data, the qualitative and quantitative variations in the Barremian-early Albian ammonite fauna of Colombia have been documented and analyzed. The position adopted here is that in the early Barremian the Andean Province became replaced by the Caribbean Subprovince in Colombia. The Caribbean Subprovince became separated as an independent unit from the Andean Province on the generic level (Buergliceras, Pedioceras), but especially on the species level. In the middle/upper Aptian many new endemic genera and subgenera appeared; Juandurhamiceras, Neodeshayesites, Laqueoceras, Zambranoites, Riedelites and Pseudoptychoceras. Besides, many endemic middle Aptian species of other, non-endemic... |

| Since the 2nd Workshop of the Lower Cretaceous Cephalopod Team in Mula, Spain (Hoedemaeker et al., 1993), several ammonite zones and ammonite horizons have been introduced that still have not be inserted in the standard zonation of the Mediterranean area. In the present survey (1) the different results of various independent specialists are compared, (2) an attempt is made to correlate their resulting zonation schemes, and (3) recommendations are given for the use of the newly introduced zones and horizons in the Mediterranean region. |
