A New Species of Gaudryceras (Ammonoidea, Gaudryceratidae) from the Lowest Maastrichtian of Hokkaido, Japan and Its Biostratigraphic Implications

Gaudryceras hobetsense sp. nov. is described from the Nostoceras hetonaiense Zone (= lowest Maastrichtian) of the Hobetsu area, south-central Hokkaido, Northern Japan. Its shell is characterized by fine lirae on early whorls, distant rounded or flat-topped, narrow band-like ribs on middle and later whorls, and frequent collar-like ribs on later whorls. The occurrence of this new species strongly suggests the presence of lowest Maastrichtian strata in southern Alaska, and sheds light on the age delineation of the chronologically poorly defined beds in northern and eastern Hokkaido.

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. -

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. -

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. -

Aptian Stage is widespread in the Central North Bulgaria, while the Albian is established only in the northern regions. The Aptian se<.:tions are built up of sediments of the Trambes and Svistov Formations. It has been es tablished that the Triimbes and Svistov Formation join laterally along the line Svi stov-Tatari- Osil m. The concretion phosphorites and sandstones, within the range of Albian, are here separated as Dekov Formations. The lithologic and ammonitic sequences in 9 sections are studied and described. Aptian Stage is represented by the Middlt: (Gargasian) and Upper (Clansayesian) Substages. The following ammonitic zones are separated and characterized: Cheloniceras ( Epicheloniceras) martinioides Zone, C. ( E. ) subnodosocostatum Zone, Acuntho hoplites no/alii Zone, Hypacanthoplites ;acobi Zone. Aptian is covered with a wash-out by Albian. The inter ruption of the sedimentation includes Late Aptian (partially), Early and Middle Albian (partially) Substages. Albian Stage is represented by the Middle (partially) and Upper Albian Substages. The following zones are esta blished and characterized: Hoplites ( Hoplites) dematus Zone, Euhoplites loricatus Zone, Euhoplites /aut us Zone, J'yfortoniceras ( Pervinquieriu) inflatum Zone, Stoliczkaia dispar Zone. In some sections the separation of the first four zones is impossible due to the strong condensation in their basement. -

Albian ammonites from northern Pakistan. Acta Geologica Polonica, 64 (1), 47–98. Warszawa. The occurrence of rich Albian ammonite faunas in what is now northern Pakistan has been known for more than 80 years, but there has been no comprehensive account of the assemblages present. A total of 36 taxa are described below. The middle part of the Lumshiwal Formation yields Upper Aptian ammonites south of the Samana Range. Elsewhere, it yields Douvilleiceras leightonense Casey, 1962, of the lower Lower Albian Leymeriella reg- ularis Zone and the Sonneratia perinflata and S. kitchini Subzones of the Sonneratia chalensis Zone of the north- west European sequence. The top one to two metres of the Lumshiwal yields an abundant fauna of rolled and phos- phatised ammonites that includes elements from much of the Albian. Of these, Prolyelliceras gevreyi (Jacob, 1907) first appears in the lower Lower Albian Leymeriella tardefurcata Zone. The commonest ammonite is Douville- iceras mammillatum (Schlotheim, 1813) sensu lato, which ranges from the perinflata Subzone of the chalensis Zone to the Otohoplites bulliensis Subzone of the O.
