Phylloceratina (Ammonoidea) Del Pliensbachiano Italiano
00 o Riv. Ital. Paleont. > n . 2 pp. 193-250 tav. 19-20 Milano 1974 PHYLLOCERATINA (AMMONOIDEA) DEL PLIENSBACHIANO ITALIANO N e r in a F a n t i n i S e s t i n i Abstract. This paper concerns thè conclusive researchs on Pliensbachian Phyllo- ceratina from Italy, among which thè genera Geyeroceras Hyatt, 1900 and Partschiceras Fucini, 1923 were already investigated (Fantini Sestini, 1969, 1971). The fossils were collected in stratigraphic sections from Selva di Zandobbio and Alpe Turati in Lombar- dy and from thè M. Nerone area in thè centrai Apennines. They consist of internai moulds and complete shells. The family Juraphyllitidae is present with genera: Jura- phyllites Miiller, Meneghiniceras Hyatt, Harpophylloceras Spath e Galaticeras Spath. Only four genera of Pliensbachian age can be attributed to thè fam. Phylloceratidae; they are as follows: Phylloceras Suess, 1865 with thè two subgenera Phylloceras s.s. e Zetoceras Kovacs, 1939. Test with ornaments visible at low magnification; internai mould smooth, section elliptical, ovai or sublanceolate; E/L and L/U with or without phylloids (minor subdivisions of folioles). Partschiceras Fucini, 1923 ( = Procliviceras Fucini, 1923; Phyllopachyceras Spath, 1925). Test with well distinct riblets, sometimes with ribs and periumbilical ridges; inter nai mould with weak constrictions in thè inner whorls and with very weakly outlined ornaments on thè venter; E/L with phylloids; Hantkeniceras Kovacs, 1939 (= Calaiceras Kovacs, 1939). Test smooth; internai mould smooth with rare weak nearly straight constrictions; L/U with 2/3 folioles jointed at their base. Calliphylloceras Spath, 1927. Test with very well developed riblets along with strong rounded ribs; internai mould smooth with 4 to 8 deep arcuate constrictions; L/U with 2 folioles jointed at their base. -
12. Lower Cretaceous Ammonites from the South Atlantic Leg 40 (Dsdp), Their Stratigraphic Value and Sedimentologic Properties
12. LOWER CRETACEOUS AMMONITES FROM THE SOUTH ATLANTIC LEG 40 (DSDP), THEIR STRATIGRAPHIC VALUE AND SEDIMENTOLOGIC PROPERTIES Jost Wiedmann and Joachim Neugebauer, Geol.-palaont. Institut der Universitat Tubingen, BRD ABSTRACT Eleven ammonites have been cored during Leg 40. They were found concentrated in the lower parts of the drilled section at Sites 363 (Walvis Ridge) and 364 (Angola Basin), and permit recognition of upper Albian, middle Albian, and upper Aptian. So far, no lower Albian could be recognized. A high ammonite density can be assumed for the South Atlantic Mid-Cretaceous. In contrast to data available so far, the Walvis Ridge associations consisting of phylloceratids and desmoceratids show more open- basin relationships than those of the Angola Basin, which are composed of mortoniceratids, desmoceratids, and heteromorphs. Paleobiogeographically, the South Atlantic fauna can be related to the well-known onshore faunas of Angola, South Africa, and Madagascar as well as to the European Mid-Cretaceous. This means that the opening of the South Atlantic and its connection with the North Atlantic occurred earlier as was generally presumed, i.e., in the middle Albian. Records of lower Aptian ammonite faunas from Gabon and Brazil remain doubtful. High rates of sedimentation prevailed especially in the Aptian and Albian, in connection with the early deepening of the South Atlantic basins. The mode of preservation of the ammonites suggests that they were deposited on the outer shelf or on the upper continental slope and were predominantly buried under sediments of slightly reducing conditions. In spite of a certain variability of the depositional environment, the ammonites show a uniform and particular mode of preservation. -

Acta Geologica Polonica, 65 (4), 545–553. Warszawa. A previously unrecorded ammonite assemblage, comprising Lepthoplites sp., Callihoplites tetragonus (Seeley, 1865), C. cf. tetragonus, Arrhaphoceras cf. substuderi Spath, 1923, Cantabrigites sp., Stoliczkaiella (Stoliczkaiella) sp., Hamites cf. duplicatus Pictet and Campiche, 1861, H. cf. subvirgulatus Spath, 1941, and H. cf. venetzianus Pictet, 1847, is described from the mid-Cretaceous condensed succession at Annopol, Poland. These specimens are pre- served as pale phosphates or sandstone moulds in a bed of reworked phosphatic nodules near the top of the Albian. This assemblage has many species in common with the late late Albian faunas from condensed deposits of Eng- land, Switzerland, and France. The presence of Callihoplites tetragonus indicates the lowermost upper upper Al- bian Mortoniceras fallax Zone. The ammonites studied are the youngest elements in the phosphate bed, which also contains taxa as old as the middle Albian Hoplites dentatus Zone. This bed originated through condensation and reworking of nodules and fossils in a period of low net sedimentation rate, being probably a reflection of a sea-level drop at the boundary between the classic ammonite zones of Mortoniceras inflatum and Stoliczkaiella dispar. -

Trans-Tethyan correlation of the Lower–Middle Cenomanian boundary interval; southern England (Southerham, near Lewes, Sussex) and Douar el Khiana, northeastern Algeria. Acta Geologica Polonica, 67 (1), 75–108. Warszawa. A 480 m section of marls with widely separated levels of nodular limestone in the Fahdene Formation north of Bou Khadra in Tebessa Province, northeastern Algeria, spans the Lower/Middle Cenomanian boundary. A total of 30 ammonite species are present, of which two: Forbesiceras reversum and Calycoceras (Newboldiceras) algeriense are new. The fauna allows recognition of the Northwest European upper Lower Cenomanian Mantelliceras dixoni Zone, the succeeding lower Middle Cenomanian Cunningtoniceras inerme Zone, the Acanthoceras rhotomagense Zone and its subzones of Turrilites costatus and Turrilites acutus. The sequence of index species occurs in the same order in both north-eastern Tunisia and the Southerham Grey Pit in Sussex (and indeed elsewhere in North- west Europe), indicating these to be robust assemblage zones and subzones that can be recognised on both the north and south sides of the Tethys. -

It is therefore not a publication in the sense of the International Code of Zoological Nomenclature. Abstract The purpose of the study was to provide conclusive evidence for a chronostratigraphical assignment of the Qihulin Formation of the Longzhaogou Group exposed in Mishan and Hulin counties of eastern Heilongjiang, northeastern China. To develop an integrated view of the formation, all collected fossil groups, i.e. the macrofossils (ammonites and bivalves) and microfossils (agglutinated foraminifers and radiolarians) have been studied. The low-diversity ammonite fauna consists of Pseudohaploceras Hyatt, 1900, and Eogaudryceras Spath, 1927, which indicate a Barremian–Aptian age. The bivalve fauna consists of eight genera and 16 species. The occurrence of Thracia rotundata (J. de C: Sowerby) suggests an Aptian age. The agglutinated foraminifers comprise ten genera and 16 species, including common Lower Cretaceous species such as Ammodiscus rotalarius Loeblich & Tappan, 1949, Cribrostomoides? nonioninoides (Reuss, 1836), Haplophragmoides concavus (Chapman, 1892), Trochommina depressa Lozo, 1944.

6. Early Cretaceous Mollusks from Dsdp Hole 397A Off Northwest Africa
6. EARLY CRETACEOUS MOLLUSKS FROM DSDP HOLE 397A OFF NORTHWEST AFRICA Jost Wiedmann, Institut für Geologie und Palàontologie, Universitát Tubingen, Federal Republic of Germany ABSTRACT Macro fossil remains in Hole 3 97 A off Cape Bojador, Tarfaya Basin, provide additional information about marine Lower Creta- ceous biostratigraphy and paleoenvironment. The ammonites have been referred to Neocomites gr. N. neocomiensis (d'Orbigny); Phyl- loceras (Hypophylloceras) thetys diegoi (Boule, Lemoine, and The- venin); and Protetragonites cf. P. crebrisulcatus (Uhlig). Although these are all long-ranging species groups, their combination support a late Hauterivian age. One bivalve (Legumenl sp.) and one gastro- pod remain {incertae sedis) are figured. The marine conditions of the off-shore Hauterivian are in con- trast to the Wealden-like terrigenous sedimentation in the on-shore Lower Cretaceous of the Tarfaya Basin, where an initial marine transgression can be recognized in the uppermost Aptian. The am- monites point to deep basinal, Tethyan relationships. INTRODUCTION bination of all data permits an appropriate age deter- mination. There has been increasing interest in the study of The stratigraphically more important specimen of macrofossils from drilled deep-sea sites (e.g., Renz, the first sample is the lytoceratid (Plate 1, Figures 2, 7) 1972; Kauffman, 1976).
