This meeting is intended to bring together people with interests in the transition period spanning the latest Jurassic to the earliest Cretaceous times and to feature disciplines covering the many aspects of stratigraphy (litho-, bio-, magneto-, chemo-, cyclo-, sequence), as well as sedimentology, paleontology, paleogeography and global tectonics, at all scales, from the SEM – Scanning Electron Microscopy – to basin analyses. The meeting is hosted by the Muséum d'Histoire naturelle de Genève and I take this opportunity to acknowledge the support provided by Jacques AYER (Director of the Museum), Dr Nadir ALVAREZ (Head of the ‘Research and Collections' Unit), Dr Lionel CAVIN (Curator, Editor-in-Chief of Revue de Paléobiologie), their staff and colleagues, among whom are Dr Christian MEISTER, Dr André PIUZ, and Dr Éric MONTEIL. The organizing committee, which also includes Prof. Rossana MARTINI, Prof. Jean J. CHAROLLAIS, and Prof. Andreas STRASSER, thanks the 15 national and international organizations that agreed to be our scientific partners. This abstract volume comprises 59 contributions, which is already an achievement. More than 70 participants representing at least 25 nationalities are attending and we wish you will all enjoy contributing to this stimulating meeting and to the debates. Bruno GRANIER President of JK2018 Note: In order to have fair, unbiased, and open discussions on the system boundary during the JK2018 meeting and to give all sides the possibility to defend their views, it was suggested that, in both abstracts and figures, the author(s) should refrain as much as possible from using “JK system boundary”, and should preferably refer to stage boundaries instead. We did not censor any abstract. Accordingly, you will find some abstracts stating that the system boundary equates to the Tithonian-Berriasian boundary (more specifically the base of the acme /abundance/ zone of Calpionella alpina), which was not the conclusion of the meeting. 1 JK2018 – December 7-5, 2018, Muséum d’Histoire naturelle de Genève Table of contents Foreword........................................................................................................................................................... 1 1.

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.

  • Age of Neuburg Formation (Bavaria, Federal Republic of Germany) and Its Correlation with the Subboreal Volgian and Mediterranean Tithonian
    Berlin • Stuttgart, 30. 3. 1989 Newsl. Stratigr. 20 (3) 149-169 Fig- Age of Neuburg Formation (Bavaria, Federal Republic of Germany) and its correlation with the Subboreal Volgian and Mediterranean Tithonian by J. A. JELETZKY t* with 2 figures Abstract. Only the topmost Bed 238 of the Neuburg Formation is a lower Upper Tithonian deposit I middle and upper microcantbum Zone). The basal Upper Tithonian (Simplisphinaes Zone) is faulted out. The rest of the Oberhausen Member (Beds 117-237) is an upper Lower Tithonian deposit (fallauxi to ponti/Burckhardticeras Zones). The Unterhausen Member (i.e. the Pseudolissoceras bavaricum Zone), except for its basal Bed 22, is a middle Lower Tithonian (= lower Middle Tithonian of some authors) deposit correlative with the semiforme/verruciferum Zone of the Mediterranean standard. The Zaraiskites scythicus Zone of Central Poland and Central Russia is roughly equivalent to the Beds 102-112 of the Unterhausen Member bearing Zaraiskites-like ammonites. Therefore, it is a middle Lower Tithonian deposit correlative with the upper S'-iiforme/verruciferum Zone. The next older Ilowaiskya pseudoscythica Zone of these two Subboreal regions corresponds to the lower semiforme/verruciferum and upper darwmil albemnum Zones of the Mediterranean Province as well as to the Bed 22 and the upper Rennertshofen Beds of the Franconian Basin. Therefore, the Central Russian Virgatites virgatus and Epivirgatites nikitmi Zones correspond to the upper Lower Tithonian fallauxi to pontilBurckhardticeras Zones of the Mediterranean standard. The entire Portlandian Stage of England is a Lower Tithonian deposit. Isterites and Pseudovirgatites are exclusively mid to late Early Tithonian genera. The controversial Central European Pseudovirgatites scruposus Zone appears to be correlative with the upper semijormel verruciferum and Zaraiskites scythicus Zones.

Buffler, and J. Blickwede, eds., The Circum-Gulf of Mexico and the Caribbean: Hydrocarbon habitats, basin 25 formation, and plate tectonics: AAPG Memoir 79, p. 545–581. Stratigraphic Constraints on the Late Jurassic–Cretaceous Paleotectonic Interpretations of the Placetas Belt in Cuba Andrzej Pszczo´łkowski Institute of Geological Sciences, Polish Academy of Sciences, Warszawa, Poland Ryszard Myczyn´ski Institute of Geological Sciences, Polish Academy of Sciences, Warszawa, Poland ABSTRACT he Placetas belt in north-central Cuba consists of Late Jurassic–Cretaceous rocks that were highly deformed during the Paleocene to middle Eocene T arc-continent collision. The Late Proterozoic marble and Middle Jurassic granite are covered by the shallow-marine arkosic clastic rocks of late Middle Jurassic(?) or earliest Late Jurassic(?) ages. These arkosic rocks may be older than the transgressive arkosic deposits of the Late Jurassic–earliest Cretaceous Con- stancia Formation. The Berriasian age of the upper part of the Constancia For- mation in some outcrops at Sierra Morena and in the Jarahueca area does not confirm the Late Jurassic (pre-Tithonian) age of all deposits of this unit in the Placetas belt. The Tithonian and Berriasian ammonite assemblages are similar in the Placetas belt of north-central Cuba and the Guaniguanico successions in western Cuba. We conclude that in all paleotectonic interpretations, the Placetas, Camajuanı´, and Guaniguanico stratigraphic successions should be considered as biogeographically and paleogeographically coupled during the Tithonian and the entire Cretaceous.

  • Remarks on the Tithonian–Berriasian Ammonite Biostratigraphy of West Central Argentina
    Volumina Jurassica, 2015, Xiii (2): 23–52 DOI: 10.5604/17313708 .1185692 Remarks on the Tithonian–Berriasian ammonite biostratigraphy of west central Argentina Alberto C. RICCARDI 1 Key words: Tithonian–Berriasian, ammonites, west central Argentina, calpionellids, nannofossils, radiolarians, geochronology. Abstract. Status and correlation of Andean ammonite biozones are reviewed. Available calpionellid, nannofossil, and radiolarian data, as well as radioisotopic ages, are also considered, especially when directly related to ammonite zones. There is no attempt to deal with the definition of the Jurassic–Cretaceous limit. Correlation of the V. mendozanum Zone with the Semiforme Zone is ratified, but it is open to question if its lower part should be correlated with the upper part of the Darwini Zone. The Pseudolissoceras zitteli Zone is characterized by an assemblage also recorded from Mexico, Cuba and the Betic Ranges of Spain, indicative of the Semiforme–Fallauxi standard zones. The Aulacosphinctes proximus Zone, which is correlated with the Ponti Standard Zone, appears to be closely related to the overlying Wind­ hauseniceras internispinosum Zone, although its biostratigraphic status needs to be reconsidered. On the basis of ammonites, radiolarians and calpionellids the Windhauseniceras internispinosum Assemblage Zone is approximately equivalent to the Suarites bituberculatum Zone of Mexico, the Paralytohoplites caribbeanus Zone of Cuba and the Simplisphinctes/Microcanthum Zone of the Standard Zonation. The C. alternans Zone could be correlated with the uppermost Microcanthum and “Durangites” zones, although in west central Argentina it could be mostly restricted to levels equivalent to the “Durangites Zone”. The Substeueroceras koeneni Zone ranges into the Occitanica Zone, Subalpina and Privasensis subzones, the A.

ROGOV Geological institute of RAS, Pyzhevskii Lane, 7, 109017 Moscow, Russia Abstract: Mollusca of northern hemisphere in Late Jurassic and most Early Cretaceous were rather distinctly geographically differentiated on boreal, which occurs in the seas, placed, as a rule, to the north of 50 parallels and tethyan inhabited the seas placed usually to the south of 45 parallels. Between these latitudes long time on the certain aquatic areas, being from time to time displaced in space, biogeographical ecotone is settled. Key words: mollusca, biogeographical ecotone, Jurassic/Cretaceous, Europe The new data received per last decade on mollusca mainly from Upper Jurassic and Lower Neocomian sequences of Europe, have allowed more precisely to establish the setting of Boreal-Tethyan ecotone in Late Jurassic and Early Neocomian and to determine a geographical position of southern border of the Boreal-Atlantic Realm (Saks et al., 1971; fig. 1а, b). The new time intervals of moving of associations and separate taxons of tethyan mollusca in Boreal basins and back are established (fig. 2). The migrations (M) with the different intensity was occur during Kimmeridgian up to Valanginian and were restricted by the Boreal-Atlantic Realm in West-European [W-Е] and East Europe [E-Е] provinces. A mollusca: an ammonites, belemnites and bivalves were divided into 4 groups: tethyan and boreal (most numerous groups), subboreal: mostly with the tethyan affinities (they were most typical for ecotones) and Arctic (assumed as extremely boreal).
