Palaeonlologia Polonica, 50, 3—94, 1990. Taxonomic and ecological analysis of the ammonite assemblages, as well as their general paleogeographical setting, indicate that the Albian deposits in the Polish part of the Central European Basin accumulated under shallow or extremely shallow marine conditions, while those of the High-Tatra Swell were deposited in an open sea environment. The Boreal character of the ammonite faunas in the epicontinental area of Poland and the Tethyan character of those in the Tatra Mountains are evident in the composition of the analyzed assemblages. -
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. -
First Record of Non-Mineralized Cephalopod Jaws and Arm Hooks
Klug et al. Swiss J Palaeontol (2020) 139:9 https://doi.org/10.1186/s13358-020-00210-y Swiss Journal of Palaeontology RESEARCH ARTICLE Open Access First record of non-mineralized cephalopod jaws and arm hooks from the latest Cretaceous of Eurytania, Greece Christian Klug1* , Donald Davesne2,3, Dirk Fuchs4 and Thodoris Argyriou5 Abstract Due to the lower fossilization potential of chitin, non-mineralized cephalopod jaws and arm hooks are much more rarely preserved as fossils than the calcitic lower jaws of ammonites or the calcitized jaw apparatuses of nautilids. Here, we report such non-mineralized fossil jaws and arm hooks from pelagic marly limestones of continental Greece. Two of the specimens lie on the same slab and are assigned to the Ammonitina; they represent upper jaws of the aptychus type, which is corroborated by fnds of aptychi. Additionally, one intermediate type and one anaptychus type are documented here. The morphology of all ammonite jaws suggest a desmoceratoid afnity. The other jaws are identifed as coleoid jaws. They share the overall U-shape and proportions of the outer and inner lamellae with Jurassic lower jaws of Trachyteuthis (Teudopseina). We also document the frst belemnoid arm hooks from the Tethyan Maastrichtian. The fossils described here document the presence of a typical Mesozoic cephalopod assemblage until the end of the Cretaceous in the eastern Tethys. Keywords: Cephalopoda, Ammonoidea, Desmoceratoidea, Coleoidea, Maastrichtian, Taphonomy Introduction as jaws, arm hooks, and radulae are occasionally found Fossil cephalopods are mainly known from preserved (Matern 1931; Mapes 1987; Fuchs 2006a; Landman et al. mineralized parts such as aragonitic phragmocones 2010; Kruta et al. -

MURPHY AND PETER U. RODDA1 University of California, Riverside, and Bureau of Economic Geology, Austin, Texas ABSTRACT—A well preserved molluscan fauna has been collected from previously undescribed Cretaceous rocks in the northwestern Sacramento Valley, California. The fossils occur in the Bald Hills formation, a 1000-foot to 1900-foot thick south- east dipping conglomerate, graywacke, and mudstone unit which ranges in age from Late Albian to Late Cenomanian. The gastropod and cephalopod elements of this fauna number thirty-two species, seventeen of which are new. New species described are: Solariella Stewarti, Tessarolax trinalis, Gyrodes allisoni, Gyrodes greeni, Ampullina stantoni, Ampullina mona, Euspira popenoei, Euspira marianus, Paleosephaea sacramentica, Clinura anassa, Acteon sullivanae, Cylichia andersoni, Marietta (Marietta) fricki, Turritites (Turritites) dilleri, Puzosia puma, Puzosia sullivanae, Eogunnarites matsumotoi.

The Upper Campanian – Lower Maastrichtian Cephalopod Fauna of Botellos, Nuevo León: a Key to Understand Faunal Turnover Acros

The Upper Campanian – lower Maastrichtian cephalopod fauna of Botellos, Nuevo León: a key to understand faunal turnover across the Campanian–Maastrichtian boundary in NE Mexico. Acta Geologica Polonica, 67 (1), 145–162. Warszawa. A new cephalopod collection from the Campanian-Maastrichtian boundary interval of NE Mexico, consisting of 1076 individuals assigned to 29 species and 22 genera is presented. This collection is a mix of ammonoids, one coleoid and one nautilid, which originate from at least three ammonoid biozones: The upper Campan- ian Exiteloceras jenneyi and Nostoceras (Nostoceras) hyatti zones, and the lower Maastrichtian Pachydiscus (Pachydiscus) neubergicus Zone. The age of the collection is thus middle late Campanian to late early Maas- trichtian, and it closes a stratigraphic gap between faunas described formerly from this region. The specimens are nuclei collected from the desert pavement. The abundance of specimens allows for a comparison to other Campanian–Maastrichtian ammonoid records from Mexico, North America and Europe. -

I966; McDougaU & Ruegg I966; Saito et al. x966; Siedner & Miller x968; Maxwell et al. I97o; Valencio & Vilas I97o ) have suggested to recent authors that initial rifling between Africa and S. America began in early or mid- Cretaceous times, while the recovery of chalks and nannofossil oozes of Albian to Cenomanian date from the Walvis Ridge (Pastouret & Goslin I974) confirms this view. In contrast, studies of distribution patterns of Cretaceous marine invertebrates, notably ammonites, from coastal basins flanking the south Atlantic (Beurlen I96I , Reyment i969-72 , Reyment & Tait I972, Cooper x972-I974) are held to indicate that a continuous marine connection between N. and S. Atlantic areas was not established until the close of the early Turonian. We would suggest on the basis of recent work on mid to late Cretaceous faunas from Angola (Cooper I972-I974) , Zululand and Natal (South Africa) (Kennedy & Klinger I97I , in press) that faunal distributions rather confirm a far earlier open marine N.-S. -

Albian and Cenomanian Ammonites of the Eastern Margin of the Lut Block (East Iran)
Carnets Geol. 16 (25) Albian and Cenomanian ammonites of the eastern margin of the Lut block (East Iran) Javad SHARIFI 1 Seyed Naser RAISOSSADAT 2, 3 Maryam MORTAZAVI MEHRIZI 4 Maryam MOTAMEDALSHARIATI 5 Abstract: Upper Albian and Lower Cenomanian ammonites occur on the eastern margin of the Lut block in eastern Iran. The ammonite assemblages described herein are from the Nimbolook and Kerch sections located west of Qayen. The following taxa are described: Mantelliceras mantelli (J. SOWERBY, 1814), Mantelliceras saxbii (SHARPE, 1857), Mantelliceras sp. 1, Mantelliceras sp. 2, Mantelliceras sp. 3, Sharpeiceras laticlavium (SHARPE, 1855), Sharpeiceras schlueteri (HYATT, 1903), Puzosia (Puzosia) mayoriana (ORBIGNY, 1841), Hyphoplites costosus C.W. WRIGHT & E.V. WRIGHT, 1949, Mortoniceras (Mortoniceras) cf. fallax (BREISTROFFER, 1940), Mantelliceras cf. mantelli (J. SOWERBY, 1814), Caly- coceras (Gentoniceras) aff. gentoni (BRONGNIART, 1822), Idiohamites fremonti (MARCOU, 1858), Mariella (Mariella) sp., Mariella (Mariella) dorsetensis (SPATH, 1926), and Turrilites costatus LAMARCK, 1801. The ammonite assemblages clearly indicate a late Albian-middle Cenomanian age for the Nimbolook section and late Albian-early Cenomanian age for the Kerch section.
