  • Oxfordian Ammonites from Hungary I. ~ O Z Y ' and G. ~ E L E N D E
    GeoResearch Forum Vols. 1-2 (1996) pp. 187-194 O 1996 Transtec Publications, Switzerland Oxfordian Ammonites from Hungary I. ~ozy'and G. ~elendez~ ' Paleontological Department of the Hungarian Natural History Museum, Pf. 330, H-1 370 Budapest, Hungary 2 Laboratory of Paleontology, Department of Geology, University of Zaragoza, E-5009 Zaragoza, Spain Kevwords: Ammonites, Jurassic, Transdanubian Central Range, Mecsek Mts, Hungary Abstract A general account of the Oxfordian sediment5 and ammonites from Hungary is given for the first time. Five ammonite associations are studied from the Gerecse and Pilis Mountains (Bakony Unit) and one from the Mecsek Mountains, in southern Hungary. They indicate a late Middle to early Upper Oxfordian age (Bifurcatus to lower Bimammatum Zone.) The age of lower ammonite associations from the Bakony Unit ranges from late Transversarium to lower Bifurcatus Zone on the basis of Passendorferia af birmensdorfensis (Moesch) and Gregoryceras fouquei (IOlian). An upper assemblage yielding among other forms, Euaspidoceras hypselum (Oppel), Benetticeras sp. and Passendorferia rozaki Melendez, is assigned to lower Hypselum Subzone, Bimammatum Zone. The ammonite association from the Mecsek Mountains contains common Aspidoceratids, including Euaspidoceras hypselum (Oppel) and Ataxioceratids including some representatives of Orthos-phinctes (M & m) close to the 0. tiziani (Oppel) group, suggesting an upper horizon within the Hypselum Subzone. INTRODUCTION In Hungary, ammonite bearing Jurassic rocks crop out in the territory of the Transdanubian Central Range (Bakony Unit) and in south, in the Mecsek and Villhy Mountains [l]. A detailed account, with full references on the Hungarian Jurassic was given lately [Z]. Since the early times of the Hungarian geology, a special attention was dedicated to the Jurassic biostratigraphy and ammonitology.

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.

ABSTRACT This study �ocuses on the lower Aptian desmoceratid �auna o� Oliete sub-basin (Teruel province). The systematic revision o� these biostratigraphy well constrained ammonites, allowed us to work on two issues. On the fist place, we improved the systematic and taxonomic knowledge about Pseudosaynella raresulcata (d’Orbigny, 1841), Pseudosaynella bicurvata (Michelin, 1838) and Pseudohaploceras liptoviensis (Zeuschner, 1856) whose definitions, previous to this study, were based on scarce material and �ew studies on their ontoge- netic variation. On a second place, we constrained their stratigraphical ranges, especially �or the Pseudosaynella species, and their correlation with the lower Aptian standard ammonite Mediterranean zonation. Keywords: lower Aptian, ammonoids, systematics, biostratigraphy, Oliete sub-basin, Iberian Chain, Te- ruel, Spain. RESUMEN Este estudio trata de la �auna de desmocer�tidos del Aptiense in�erior de la subcuenca de Oliete (provincia de Teruel).

E-mail: [email protected] ABSTRACT: Kennedy, W.J. and Gale, A.S. 2017. 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.

FATMI2 1Oxford University Museum of Natural History, Parks Road, Oxford OX1 3W and Department of Earth Sciences, Parks Road, Oxford OX1 3AN, United Kingdom. E-mail: [email protected] 2Formerly of the Geological Survey of Pakistan, Quetta, Pakistan (Dr Fatmi died on 27 March 2012) ABSTRACT: Kennedy, W.J. and Fatmi, A.N. 2014. 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.

This faunal turnover took place following a stepwise pattern. The first step occurred at the boundary between the Pseudothurmannia ohmi Subzone and the Pseudothurmannia mortilleti Subzone, coinciding with the base of the so-called Faraoni Level. This is a Corg- rich interval that has been recognised in several basins of the Mediterranean Tethys and seems to be the expression of a short- lived oxygen-deficient event. It correlates with a well-documented second-order peak transgression. The oxygen depletion preferentially affected the deep nektic ammonites, which would explain the extinctions within this group around the Faraoni Level. On the contrary, an increase in the trophic resources in the photic zone favoured the diversification of epipelagic ammonites. Concurrently, an abrupt change took place at this level in the nannoconid assemblage composition. A minor second event, located at the base of the Pseudothurmannia picteti Subzone, was marked by the replacement of a few planktic ammonite species by closely related forms, and the structure of the ammonite assemblage was not substantially altered.

The material was collected in late Aptian rocks of the Kotick Point Formation outcropping in the western part of James Ross Island, near Antarctic Peninsula. It consists of an isolated tooth assignable to a hexanchiform different from the other described genera. The tooth shows putative plesiomorphic cusp (few cusps, no serrations) and apomorphic root characters (relatively deep, quadrangular). It could be related to a species close to the origin of Hexanchus (unknown in beds older than Cenomanian).
