New and Poorly Known Perisphinctoidea (Ammonitina) from the Upper Tithonian of Le Chouet (Drôme, SE France)
Volumina Jurassica, 2014, Xii (1): 113–128 New and poorly known Perisphinctoidea (Ammonitina) from the Upper Tithonian of Le Chouet (Drôme, SE France) Luc G. BULOT1, Camille FRAU2, William A.P. WIMBLEDON3 Key words: Ammonoidea, Ataxioceratidae, Himalayitidae, Neocomitidae, Upper Tithonian, Le Chouet, South-East France. Abstract. The aim of this paper is to document the ammonite fauna of the upper part of the Late Tithonian collected at the key section of Le Chouet (Drôme, SE France). Emphasis is laid on new and poorly known Ataxioceratidae, Himalayitidae and Neocomitidae from the upper part of the Tithonian. Among the Ataxioceratidae, a new account on the taxonomy and relationship between Paraulacosphinctes Schindewolf and Moravisphinctes Tavera is presented. Regarding the Himalayitidae, the range and content of Micracanthoceras Spath is discussed and two new genera are introduced: Ardesciella gen. nov., for a group of Mediterranean ammonites that is homoeomorphic with the Andean genus Corongoceras Spath, and Pratumidiscus gen. nov. for a specimen that shows morphological similarities with the Boreal genera Riasanites Spath and Riasanella Mitta. Finally, the occurrence of Neocomitidae in the uppermost Tithonian is documented by the presence of the reputedly Berriasian genera Busnardoiceras Tavera and Pseudargentiniceras Spath.

Stratigraphic Implications of a New Lower Cretaceous Ammonoid Fauna from the Puez Area (Valanginian – Aptian, Dolomites, Southern Alps, Italy)
Geo.Alp, Vol. 3, S. 55–83, 2006 STRATIGRAPHIC IMPLICATIONS OF A NEW LOWER CRETACEOUS AMMONOID FAUNA FROM THE PUEZ AREA (VALANGINIAN – APTIAN, DOLOMITES, SOUTHERN ALPS, ITALY) Alexander Lukeneder1 & Christian Aspmair2 With 6 figures and 8 plates 1 Natural History Museum, Geological-Palaeontological Department, Burgring 7, A-1010 Wien, Austria, e-mail: [email protected] 2 Prissian 102, I – 39010 Tisens (BZ), Italy Abstract Lower Cretaceous ammonoids (n = 424) were collected at the Puez locality in the Dolomites of Southern Tyrol. The cephalopod fauna from the marly limestones to marls here indicates Late Valanginian to Early Aptian age. The deposition of the marly limestones and marls of this interval occurred during depositional- ly unstable conditions. The underlying Biancone Formation (Maiolica Formation) is of Early Valanginian, whereas the lowermost Rosso Ammonitico is of Jurassic to Berriasian age. The ammonoid fauna consists of 27 different genera, each represented by 1-2 species. The assemblage at the Puez section is dominated by the Phylloceratina (30%) and the Ammonitina (34%). Phyllopachyceras (17%) and Phylloceras (13%) (both Phylloceratina) are the most frequent components, followed by Lytoceras (12%) (Lytoceratina), and Barremites (10%) and Melchiorites (8%) (both Ammonitina). The cephalopod fauna is purely of Mediterranean origin. Zusammenfassung Unterkreide Ammonoideen (424 Exemplare) der Puez Lokalität in den Dolomiten Süd-Tirols wurden unter- sucht. Die Fauna der mergeligen Kalke und Mergel von Puez zeigen ein Alter von Ober-Valanginium bis Unter-Aptium an. Die mergeligen Kalke und Mergel dieses Abschnitts lagerten sich unter instabiler Bedingungen ab. Die unterlagernde Biancone Formation (Maiolica Formation) zeigt Unter-Valanginium an, wogegen die tiefste Formation des Rosso Ammonitico auf Ober-Jura bis Berriasium hindeutet. -

The Barremian Heteromorph Ammonite Dissimilites from Northern Italy: Taxonomy and Evolutionary Implications
The Barremian heteromorph ammonite Dissimilites from northern Italy: Taxonomy and evolutionary implications ALEXANDER LUKENEDER and SUSANNE LUKENEDER Lukeneder, A. and Lukeneder, S. 2014. The Barremian heteromorph ammonite Dissimilites from northern Italy: Taxon- omy and evolutionary implications. Acta Palaeontologica Polonica 59 (3): 663–680. A new acrioceratid ammonite, Dissimilites intermedius sp. nov., from the Barremian (Lower Cretaceous) of the Puez area (Dolomites, northern Italy) is described. Dissimilites intermedius sp. nov. is an intermediate form between D. dissimilis and D. trinodosum. The new species combines the ribbing style of D. dissimilis (bifurcating with intercalating single ribs) with the tuberculation style of D. trinodosum (trituberculation on entire shell). The shallow-helical spire, entirely comprising single ribs intercalated by trituberculated main ribs, is similar to the one of the assumed ancestor Acrioceras, whereas the increasing curvation of the younger forms resembles similar patterns observed in the descendant Toxoc- eratoides. These characters support the hypothesis of a direct evolutionary lineage from Acrioceras via Dissimilites to Toxoceratoides. D. intermedius sp. nov. ranges from the upper Lower Barremian (Moutoniceras moutonianum Zone) to the lower Upper Barremian (Toxancyloceras vandenheckii Zone). The new species allows to better understand the evolu- tion of the genus Dissimilites. The genus appears within the Nicklesia pulchella Zone represented by D. duboise, which most likely evolved into D. dissimilis. In the Kotetishvilia compressissima Zone, two morphological forms developed: smaller forms very similar to Acrioceras and forms with very long shaft and juvenile spire like in D. intermedius sp. nov. The latter most likely gave rise to D. subalternatus and D. trinodosum in the M. -

Palaeontology and Biostratigraphy of the Lower Cretaceous Qihulin
Dissertation Submitted to the Combined Faculties for the Natural Sciences and for Mathematics of the Ruperto-Carola University of Heidelberg, Germany for the degree of Doctor of Natural Sciences presented by Master of Science: Gang Li Born in: Heilongjiang, China Oral examination: 30 November 2001 Gedruckt mit Unterstützung des Deutschen Akademischen Austauschdienstes (Printed with the support of German Academic Exchange Service) Palaeontology and biostratigraphy of the Lower Cretaceous Qihulin Formation in eastern Heilongjiang, northeastern China Referees: Prof. Dr. Peter Bengtson Prof. Pei-ji Chen This manuscript is produced only for examination as a doctoral dissertation and is not intended as a permanent scientific record. 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. The radiolarians comprise ten genera and 17 species, where Novixitus sp., Xitus cf. -

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).
