Over 130 species are documented from the Upper Albian, Cenomanian and Upper Turonian Fahdène Formation and correlatives in Central Tunisia and northern Algeria, based on material described by Henri Coquand (1852, 1854, 1862, 1880), Léon Pervinquière (1907, 1910), Georges Dubourdieu (1953), Jacques Sornay (1955), and new collections. The material consists predominantly of limonitic nuclei, together with adults of micromorphs. There is no continuous record, and a series of faunas are recognised that can be correlated with the zonation developed in Western Europe. These are the Upper Albian Ostlingoceras puzosianum fauna, Lower Cenomanian Neostlingoceras carcitanense and Mariella (Mariella) harchaensis faunas, the upper Lower to lower Middle Cenomanian Turrilites scheuchzerianus fauna, Middle Cenomanian Calycoceras (Newboldiceras) asiaticum fauna, Upper Cenomanian Eucalycoceras pentagonum fauna, and the Upper Turonian Subprionocyclus neptuni fauna. Two new micromorph genera are described, Coquandiceras of the Mantelliceratinae and Cryptoturrilites of the Turrilitinae. Most of the taxa present have a cosmopolitan distribution, with a minority of Boreal, North American and endemic taxa.

The present paper discusses foraminiferal assemblages and biozones established on the basis of studies of samples from ten borehole sequences of the Khanty-Mansiysk Horizon in the Samotlor area of the northern palaeobiogeographical district of western Siberia (Russia). In this region, middle and late Albian foraminiferal assemblages were first distinguished in western Siberia. Levels from which these assemblages have been recovered, are here referred to the following foraminiferal zones, the Ammobaculites fragmentarius–Gaudryinopsis filiformis Zone (middle Albian) and the Ammotium braunsteini–Verneuilinoides borealis assanoviensis Zone (upper Albian). Zonal assemblages are dominated by representatives of the orders Ammodiscida, Textulariida and Ataxophragmiida. Species of the ataxophragmiid genera Verneuilinoides, Pseudoverneuilina and Gaudryinopsis are the most characteristic, inclusive of several key index forms. Foraminiferal tests consist of agglutinated quartz-silica, the wall microstructure being almost exclusively medium and coarse grained. In specific composition, the Albian assemblages from the Samotlor area are similar to those from Transuralia (Russia) and to the Canadian Province, which, together with West-Siberian Province, forms the Arctic palaeobiogeographical realm.

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 regularis Zone and the Sonneratia perinflata and S. kitchini Subzones of the Sonneratia chalensis Zone of the northwest European sequence. The top one to two metres of the Lumshiwal yields an abundant fauna of rolled and phosphatised 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 Douvilleiceras mammillatum (Schlotheim, 1813) sensu lato, which ranges from the perinflata Subzone of the chalensis Zone to the Otohoplites bulliensis Subzone of the O. auritiformis Zone of the Lower Albian. The presence of Lyelliceras pseudolyelli (Parona and Bonarelli, 1897) indicates the uppermost, pseudolyelli Subzone of the auritiformis Zone. The presence of Lyelliceras lyelli (d’Orbigny, 1841) indicates the basal Middle Albian lyelli Subzone of the Hoplites dentatus Zone. There is no evidence for the higher parts of the Middle Albian. Dipoloceras (Rhytidoceras ) sp. indicates the presence of lower Upper Albian, possibly the pricei Zone. There is evidence, in the form of specifically indeterminate Mortoniceras (Mortoniceras) sp., of a level within the inflatum to fallax Zone inteval from a single locality, but no evidence of the succeeding parts of the upper Upper Albian. The base of the Kawagarth Formation that succeeds the Lumshiwal yields lower Upper Albian Mortoniceras (M.) geometricum Spath, 1932 of the Mortoniceras pricei Zone, northwest of Darmasand in the Samana range.

The first records of pterosaurs from the Cretaceous of Poland are reported, on the basis of fragmentary remains from the marine Upper Albian (Lower Cretaceous) of the Annopol Anticline, central Poland. The new material consists of four bone fragments, tentatively interpreted as: 1) a portion of wing phalanx; 2) a medial element of fused skull bones (parietal crest?); 3) a fragmentary carpal or tarsal; and 4) a distal phalanx of the pes (or a very small fragment of a long cervical vertebra). Previously, only the remains of marine vertebrates have been reported from the Cretaceous of the Annopol area. The pterosaur fossils studied most probably belonged to individuals that died while over the sea. The possibility that they represent remains dropped from floating carcasses, introduced into the marine environment by rivers, is regarded as less probable, as there are no remains of dinosaurs or other terrestrial fauna in the Annopol deposits.

Oyster-bioimmured ammonites from the Upper Albian of Annopol, Poland: stratigraphic and palaeobiogeographic implications

EN

Ammonites Mortoniceras (Subschloenbachia) sp. are preserved as attachment scars on the oyster shells from the topmost portion of the Albian succession at Annopol, Poland. These oyster-bioimmured ammonites show a closest affinity to the representatives of Mortoniceras (Subschloenbachia) characteristic of the upper Upper Albian Mortoniceras perinflatum Zone. No ammonites indicative of the uppermost Albian–lowermost Cenomanian Praeschloenbachia briacensis Zone are recorded. Thus, the hiatus at the Albian–Cenomanian boundary at Annopol embraces the latter zone. The presence (and dominance) of Mortoniceras in the upper Upper Albian ammonite assemblage of Annopol suggests that the representatives of this Tethyan genus could migrate into the epicratonic areas of Poland directly from the Tethyan Realm, via the Lwów (Lviv) region.

EN

Peculiarly shaped, relatively large (up to 30 cm in diameter) concretions of quartzitic sandstone occur in a single horizon of Upper Albian loose sands in the Cracow Upland, southern Poland. They are characterized by hollow interiors adorned with mass-aggregated moulds of the borings of diverse sponges, polychaetes and bivalves. These moulds represent the siliceous filling of borings in limestone clasts that had been subject to dissolution, leaving a hollow within the concretion that had formed around them. Synsedimentary block-faulting and jointing affected the Jurassic limestone-basement, causing the uplift of a local horst (the Glanow Horst), to within the littoral zone so that it became exposed to abrasion. It is inferred that a hurricane or catastrophic storm surge swept limestone debris fallen from the cliff out to the sandy offshore, where nucleation of soluble silica was presumably favoured by the decay of the soft tissue of live or dead rock-borers. After filling the emptyo borings and solution of the limestone clasts, the nucleation progressed intensely, finally completed by precipitation of siliceous sinter in the hollow interiors of some of the concretions during subsequent diagenesis and/or epigenesis.

The macrofaunal content of an exceptionally fossiliferous Late Albian core section is described from Zippelsforde in the Brandenburg district in eastern Germany. The main faunal horizon includes among others Euhoplites vulgaris, Mortoniceras (Deiradoceras) albense, Neohibolites minimus, Inoceramus cf. anglicus and Actinoceramus sulcatus. This assemblage indicates a Hysteroceras varicosum Zone, Hysteroceras orbignyi Subzone age. That interval is known from the Anglo-Paris as well as from the Lower Saxony Basin in western Germany, but not was previously recorded from the North East German Basin. Therefore, the record fills a palaeogeographical gap between the Albian in the Carpathians and that of Central Europe. The superjacent interval contains Aucellina gryphaeoides, dating it as latest Albian (Mortoniceras (M.) inflatum Zone, late C. auritus Subzone or younger), and thus indicating a significant condensation within the Late Albian.

A 100 metre succession of Upper Upper Albian sediments in the Montlaux section (les Gipieres-Champfleury), Alpes-de-Haute Provence, France yielded a series of ammonites that provide unequivocal evidence for a Mortoniceras (Subschloenbachia) rostratum ammonite Zone succeeded by a Mortoniceras (Subschloenbachia) perinflatum ammonite Zone. On this basis, and evidence from successions described previously, the classic Upper Upper Albian Stoliczkaia dispar Zone is replaced by a sequence, from oldest to youngest, of Mortoniceras (Mortoniceras) fallax, Mortoniceras (Subschloenbachia) rostratum, Mortoniceras (Subschloenbachia) perinflatum and Arrhaphoceras (Praeschloenbachia) briacensis Zones.The following species are described: Anagaudryceras sacya (FORBES, 1846), Desmoceras latidorsatum (MICHELIN, 1838), Puzosia (Puzosia) mayoriana (D.ORBIGNY, 1841), Pleurohoplites renauxianus (D.ORBIGNY, 1840), Arrhaphoceras sp., Discohoplites simplex WRIGHT & WRIGHT, 1949, Discohoplites subfalcatus (SEMENOV, 1899), Mortoniceras (Subschloenbachia) rostratum (J.SOWERBY, 1817), Mortoniceras (Subschloenbachia) perinflatum (SPATH, 1922b), Stoliczkaia (Stoliczkaia) dispar (D.ORBIGNY, 1841), Stoliczkaia (Stoliczkaia) clavigera NEUMAYR, 1875, Anisoceras armatum (J.SOWERBY, 1817), Anisoceras perarmatum PICTET & CAMPICHE, 1861, Anisoceras pseudoelegans PICTET & CAMPICHE, 1861, Idiohamites elegantulus SPATH, 1939, Hamites venetzianus PICTET, 1847, Lechites (L.) gaudini (PICTET & CAMPICHE, 1861), Lechites (L.) moreti BREISTROFFER, 1936, Mariella (Mariella) bergeri (BRONGNIART, 1822), Ostlingoceras (Ostlingoceras) puzosianum (D.ORBIGNY, 1842), and Scaphites (Scaphites) sp.

In the Klape Unit of the Pieniny Klippen Belt the Albian conglomerates with clasts of exotic carbonates, clastic sediments and also volcanic and plutonic rocks are relatively widespread. In the small area near the town Povażska Bystrica also scarce blueschist clasts of variegated petrographic types have been found. Three groups of starting rocks can be discerned for blueschists: pelagic sediments, metamorphic rocks (amphibolites, gneisses) and volcanic rocks. Based on immobile trace element (HFSE, REE) distribution two petrogenetic types of volcanic rocks have been identified: basalts with BABB signature and calc-alkaline basaltic andesites to rhyolites. Source of these rocks was probably a nappe stack located in the Carpathian interior and created in the Late Jurassic time as a result of subduction of the oceanic crust and adjacent volcanic arc and followed by collision during the Meliata Ocean closure

Albskie zlepieńce jednostki klapskiej pienińskiego pasa skałkowego zawierające egzotyki skał węglanowych, klastycznych, jak również wulkanicznych i plutonicznych są szeroko rozprzestrzenione. Na małym obszarze w okolicy Povażskiej Bystricy (Słowacja zachodnia) w kilku stanowiskach znaleziono rzadkie egzotyki zróżnicowanych petrograficznie łupków glaukofanowych. Wyróżniono trzy grupy pierwotnych utworów przekształconych w te łupki: osady pelagiczne, skały metamorficzne (amfibolity, gnejsy) i skały wulkaniczne. W oparciu o niestabilne pierwiastki śladowe (HFSE, REE) zidentyfikowano dwa typy petrogenetyczne skał wulkanicznych: bazalty o cechach bazaltów obszarów zaułkowych (BABB) oraz wapniowo-alkaliczne andezyty i ryolity bazaltowe. Obszarem źródłowym tych skał były prawdopodobnie spłaszczowinowane jednostki zlokalizowane w obrębie Karpat wewnętrznych, powstałe w późnej jurze jako rezultat subdukcji skorupy oceanicznej i utworzonego w związku z tym łuku wulkanicznego, w następstwie kolizji podczas zamykania się oceanu Meliaty

A re-examination of the type material of Ammonites senequieri D'Orbigny, 1841, the type species of Brancoceras Steinmann, 1881, shows D'Orbigny's original figures to be a chimaera, based on specimens of two species, while the other specimens in his collection belong to several other species, many of them named by Collignon (1949), all of which are revised. The following species are described: Brancoceras senequieri (D'Orbigny, 1841), B. magneti Collignon, 1949, B. helcion (Reynes, 1876), B. subcompressum Collignon, 1949, B. paronai Collignon, 1949, B. retrorsum Collignon, 1949, B. alternatum sp. nov., B. flexuosum sp. nov., and B. multicostatum sp.nov. Ammonites versicostatus Michelin, 1838, referred to Brancoceras by some authors, belongs to Lyelliceratinae, as proposed most recently by Latil (1995), and is a brancoceratid homeomorph referred to Pseudobrancoceras gen. nov., of which it is the type species, and to which a second species, P. transiens sp. nov., is also referred.

Shallow-water scleractinian corals from Cretaceous allochthonous sediments of Subpelagonian Zone in Agrostylia (Parnassos region, Central Greece) represent 47 taxa belonging to 35 genera, 15 families and 8 suborders; of these 3 new genera and 9 new species are described. Among these taxa, 5 were identified only at the generic level. One octocorallian species has also been identified. This coral assemblage is representative for late Early Cretaceous Tethyan realm but also shows some endemism. A characteristic feature of this scleractinian coral assemblage is the abundance of specimens from the suborder Rhipidogyrina. The Albian age of the corals discussed is indicated by the whole studied coral fauna, associated foraminifers, calpionellids and calcareous dinoflagellates.
