A részben saját költségén megtett utazásai során (1911–1912) MILLEKER — számos más természetrajzi érték mellett — jelentős mennyiségű alsó-jura ősmaradványt gyűjtött az Ankara közelében fekvő Jakadjik (vagy Jakadsik, mai nevén Yakacik) lelőhelyről. A kövületeket — köztük a nagyszámú brachiopodát — jórészt VADÁSZ (1913a, b, 1918) dolgozta fel és publikálta. Az anyag a budapesti Földtani Intézet múzeumába került, ahol ma is becses részét képezi a Magyar Földtani és Geofizikai Intézet gyűjteményének. Vadász úttörő, de előzetes jellegű, szinte vázlatos publikációi, valamint a bennük foglalt, többnyire elavult rendszertani eredmények indokolttá tették a brachiopoda fauna korszerű rendszertani revízióját. A revízió szerint a 197 brachiopoda példány 27 taxont képvisel. Ezen belül 16 genuszhoz tartozó, 23 névleges fajt sikerült azonosítani; ezek részletes leírását és fotódokumentációját adja a jelen dolgozat, a szükséges esetekben sorozatcsiszolati rajzokkal kiegészítve. A 23 faj közül csupán 8 szerepelt VADÁSZ (1913a, b, 1918) publikációiban. A múzeumi alátét cédulák tanúsága szerint azonban VADÁSZ tovább dolgozott az anyagon: a cédulákon szereplő határozásai közül 12 egyezik a mostani revízióban szereplő fajnevekkel.

  • Brachiopods from the Barremian Turbiditic Formations of Serre De Bleyton, Drôme (SE France)
    Ann. Naturhist. Mus. Wien, Serie A 113 655–673 Wien, Mai 2011 Brachiopods from the Barremian turbiditic formations of Serre de Bleyton, Drôme (SE France) By Danièle GASPARD (with 3 plates and 1 figure) Manuscript submitted on September 1st 2009, the revised manuscript on September 9th 2010 Abstract Brachiopods from three outcrops sampled in the Barremian tubiditic formations, from Serre de Bleyton, Drôme (SE France) by G. MOOSLEITNER, reveal a great biodiversity. In the large sam- ples obtained and dispatched to different specialists, lots of small organisms exist, among them Rhynchonelliform brachiopods. The shells observed are recognized as size-sorted and transported specimens trapped in a mud-flow. These specimens, representatives of Rhynchonellida, Thecideida, Terebratulida, are described following their morphological characteristics. The present state of the deltidial plates, among morphological characteristics, and the geological and sedimentologi- cal contexts from which they are extracted lead to the conclusion in favour of juvenile rather than micromorphic specimens. Keywords: Juvenile brachiopods, Rhynchonellida, Terebratulida, Thecideida, Barremian, SE France, turbidites. Introduction Many small entire or disarticulated brachiopod shells have been revealed from three out- crops in a turbiditic series at Serre de Bleyton, Drôme provençale, in the Commune of Arnayon (SE France). These Lower Cretaceous brachiopods are mainly smooth, poorly preserved, and result from size-sorted brachiopod populations, i.e. reworked assemblages. In such a context, it is difficult to be precise about a geologic age, i.e. precise zonal refer- ences, for this material redeposited from an outer shelf into an upper slope environment. The samples are juvenile specimens, in this case the evaluation must be made with cau- tion.

Brachiopods occur in the Gingin Chalk in the Perth Basin and in the Toolonga Calcilutite, Korojon Calcarenite and Miria Formation in the Carnarvon Basin. Fifteen species of brachiopods are described or revised from the Santonian to Campanian Gingin Chalk, seven species from the Santonian to Campanian Toolonga Calcilutite, two species from the Campanian to Maastrichtian Korojon Calcarenite and five species from the Late Maastrichtian Miria Formation. Ten new species are described: EolzwlItlzyns mlnaenSlS sp. nov., E.

A new family, Zenobiathyridae, is proposed. The presence of a number of genera common to Late Cretaceous and "early Tertiary" of the deposits Antarctic Peninsula suggests that there was a continuous shelf between Western Australia and Antarctica during this period. It is proposed that these brachiopods form part of a high latitude southern circum-Indo-Atlantic faunal province which existed during the Late Cretaceous to the early Cenozoic.

SANDY 1 (1 table, 1 plate) Key words: Palaeozoic, Mesozoic, Brachiopoda, palaeoecology, palaeobiogeography Abstract The apparently anomalous palaeoecology and palaeobiogeography of a number of Palaeozoic and Mesozoic brachiopod genera known from only a few geographically dispersed localities (or even only one), can be understood by interpreting their occurrences as members of, or associates of chemosynthetic communities (cold seeps, or low-temperature hydrothermal vents). This is based on an assessment of aspects of their geological setting-stratigraphy, sedimentology and palaeontology. A cold seep interpretation is significant in explaining disjunct problematic palaeobiogeographic patterns and palaeoecological models with no modern analogues that have previously been proposed to explain their occurrence. Összefoglalás Számos paleozoós és mezozoós brachiopoda nemzetség képviselői csupán néhány, földrajzilag egymástól távol eső lelőhelyről (vagy éppen csak egy lelőhelyről) ismertek. E nemzetségek látszólag anomális paleoökológiai és paleobiogeográfiai eloszlása érthetővé válik, ha képviselőiket

Bulletin of the Geological Society of Denmark, Vol. 52, pp. 213–225. © 2005 by Geological Society of Denmark. ISSN 0011–6297. Augmentation and revision of the relatively diverse Valanginian brachiopod faunas from North- East Greenland confirm the existence of two mutually exclusive but broadly coeval assemblages, associated with two contrasting facies types. A Boreal, relatively shallow-water assemblage domi- nated by large terebratulids and ribbed rhynchonellids, including Cyrtothyris, Lamellaerhynchia and Praelongithyris characterizes the Falskebugt fauna. By contrast the Albrechts Bugt and Rødryggen fauna contains Tethyan elements, more typical of deeper water, including Lacunosella, Placothyris, Pygope and Rugitela. This early Cretaceous Out-of-Tethys migration confirms the early and persist- ent northward track of a proto Gulf Stream current. A new taxon, Placothyris kegeli, is described from the Albrechts Bugt and Rødryggen members of the Palnatokes Bjerg Formation.

    Mesozoic Brachiopods of Alpine Europe Hungarian Geological Society, Budapest, 1993 Edited by J. PÁLFY and A. VÖRÖS pp. 59–68, ISBN 963 8221 14 3 PYGOPID BRACHIOPODS AND TETHYAN MARGINS Miklós KÁZMÉR Department of Paleontology, Eötvös University, H–1083 Budapest, Ludovika tér 2, Hungary ABSTRACT—Paleogeographic distribution patterns of four perforated species of the Upper Jurassic– Lower Cretaceous Pygopidae (Brachiopoda) were studied in the Alpine–Carpathian–Balkan region. Pygope catulloi and P. diphya, bearing small perforations near their umbones lived in the southern margin of Tethys, while Pygope janitor and Pygites diphyoides with large, central perforations lived on the northern margin. Their separation was caused either by a wide Penninic ocean acting as a barrier, or rather by the adaptation of the forms with smaller perforations to the nutrient-poor environment of the southern margin.

    FRAGMENTA PALAEONTOLOGICA HUNGARICA 21, BUDAPEST, 2003 Early Jurassic fauna and facies of the Schafberg area (Salzkammergut, Austria) by Attila VÖRÖS, János SZABÓ, Alfréd DULAI, István SZENTÉ, Oskar EBLI «Sc Harald LOBITZER Abstract — In order of a complex reexamination of the Jurassic faunas of the Schafberg and closely connected area, the authors carried out new collecing and sampling. The studied area contains localities of classical palaeontological monographs, based on fossils of the Lower Liassic Mierlatz Formation and some other associated limestones. During the field work we attempted to locate the classical sites but most of the exposures are new. Characteristic megafossils are the brachiopods but bivalves and gastropods are also found. Beside notices on the microfacies and microfossils, the identified species of the faunas are listed below, and, some palaeontological remarks are added to most of the listed species. The faunal lists are partly completed with museum materials. Keywords — Early Jurassic, microfacies, bivalves, gastropods, brachiopods VÖRÖS, A., SZABÓ, J., DULAI, A., SZENTÉ, I., EBLI, O. & LOBITZER, H.

Introduction Mt Schafberg belongs to the classical areas of Liassic SPENGLER (1911), who had been WÄHNER'S student, research in the Northern Calcareous Alps and several published the most comprehensive description of the monographies dating back to the 19th century deal with geology of Schafberg, situated within the "Schafberg- the rich mega- and microfauna from various lithologies. Tirolikum" tectonic unit. SPENGLER initiated also the The first comprehensive description of the rich mega- first microfacies study of the Schafberg region by fauna of the Hierlatz Limestone we owe to HAUER (1853, LEISCHNER (1969).
