This crater is 5.6 km in diameter and penetrates Cambrian and Ordovician cratonic strata. It was probably situated close to land in an embayment connected to the epicontinental sea; typical shelly marine taxa are absent. The Konservat-Lagerstätte within the Winneshiek Shale is important because it represents an interval when exceptional preservation is rare. The biota includes the earliest eurypterid, a giant form, as well as a new basal chelicerate and the earliest ceratiocarid phyllocarid. Conodonts, some of giant size, occur as bedding plane assemblages. Bromalites and rarer elements, including a linguloid brachiopod and a probable jawless fish, are also present. Similar fossils occur in the coeval Ames impact structure in Oklahoma, demonstrating that meteorite craters represent a novel and under-recognized setting for Konservat- Lagerstätten. -

CONODONTS OF THE MOJCZA LIMESTONE JERZY DZIK Dzik, J. 1994. Conodonts of the M6jcza Limestone. -In: J. Dzik, E. Olemp ska, and A. Pisera 1994. Ordovician carbonate platform ecosystem of the Holy Cross Moun tains. Palaeontologia Polonica 53, 43-128. The Ordovician organodetrital limestones and marls studied in outcrops at M6jcza and Miedzygorz, Holy Cross Mts, Poland, contains a record of the evolution of local conodont faunas from the latest Arenig (Early Kundan, Lenodus variabilis Zone) to the Ashgill (Amorphognathus ordovicicus Zone), with a single larger hiatus corre sponding to the subzones from Eop/acognathus pseudop/anu s to E. reclinatu s. The conodont fauna is Baltic in general appearance but cold water genera , like Sagitto dontina, Scabbardella, and Hamarodus, as well as those of Welsh or Chinese af finities, like Comp/exodus, Phragmodus, and Rhodesognathu s are dominant in par ticular parts of the section while others common in the Baltic region, like Periodon , Eop/acognathus, and Sca/pellodus are extremely rare. Most of the lineages continue to occur throughout most of the section enabling quantitative studies on their phyletic evolut ion. Apparatuses of sixty seven species of thirty six genera are described and illustrated. Phyletic evolution of Ba/toniodus, Amorphognathu s, Comp/exodus, and Pygodus is biometrically documented. Element s of apparatu ses are homolog ized and the standard notation system is applied to all of them. Acodontidae fam. n., Drepa nodus kie/censis sp. n., and D. santacrucensis sp. n. are proposed .

No. 2] Proc. Japan Acad., 56, Ser. B (1980) 69 14. Discovery of Triassic Conodonts from Malajon and Uson Islands of the Calamian Island Group, Palawan Province, the Philippines, and Its Geological Significance By wataru HASHIM0T0,*) Shigeru TAKIZAWA,**) Guillermo R. BALCE, * * * ) Ernesto A. ESPIRITU, * * * and Crisanto A. BAURA* * * > (Communicated by Teiichi KoBAYASxi, M. J. A., Feb. 12, 1980) This short article deals with the discovery of Epigondolella ab- neptis (Huckriede) , a Lower Norian index conodont of Japan, in the limestone at the southeastern coast of Malajon Island, the Calamian Island Group, and its geological significance. The general geology of the Calamian Island Group had not been surveyed since Smith (1924) reported the manganese-bearing chert formation from Busuanga Island and limestone from Coron Island, until 1978, when H. Fontaine reported the geological and palaeon- tological results of his reconnaissance works conducted in this island group (Fontaine, 1978, 1979; Fontaine et al., 1979). The Calamian Island Group is geographically situated between Mindoro and Palawan Islands, where the Mindoro and the Palawan Metamorphics are exposed respectively. Concerning the origin of these schists in the Recent Palawan Arc trending from Palawan to Mindoro, Gervasio (1971) and Hashimoto and Sato (1973) are of different opinions. Gervasio (1971) referred to the schist in the Palawan Arc as the basement of the Philippines and the non-metamorphosed Palaeozoic sediments including limestone in northern Palawan as well as that in the Calamian Island Group and the Permian limestone on Carabao Island as Palaeozoic formation deposited in a miogeosyncline, occur- ring in an east-west direction upon the basement schist terrain. -

Misikella Ultima Kozur & Mock, 1991: First Evidence of Late Rhaetian
Bollettino della Società Paleontologica Italiana Modena, Novembre 1999 Misikella ultima Kozur & Mock, 1991: first evidence of Late Rhaetian conodonts in Calabria (Southern Italy) Adelaide MASTANDREA Claudio NERI Fabio lETTO Franco Russo Di p. di Scienze della Terra Di p. di Se. Geo!. e Paleomol. Dip. di Scienze della Terra Dip. di Scienze della Terra Univ. di Modena e Reggio Emilia Università di Ferrara Università di Napoli Federico II Università della Calabria KEY- WORDS- Conodonts, Clusters, Biostratigraphy, Basin deposits, Catena Costiera, Calabria, Rhaetian. ABSTRACT- The succession cropping out in the Fosso Pantanelle area (Mt. S. Giovanni, Calabrian "Catena Costiera'; Upper Trias) provided a rich and well preserved conodont fauna. The basin stratigraphic succession is characterized by cherty lime mudstone with minor fine- grained calciturbidites and suspected tujìtes. Conodont founa is dominated by M. hernsteini and M. posthernsteini in the lower and middle part of the section, and by M. uftima in the uppermost part. Every species is represented by a great number of specimens. On the basis of the chronostratigraphic classification ofKozur & Mock (1991), the whole section may be referred to Rhaetian. Due to the good preservation and the great abundance of conodonts (some occurring in clusters), the calabrian Catena Costiera succession may represent a reference succession for the study ofthe latest Triassic conodont founas and chronostratigraphy.

[email protected] Received: 26/02/06 / Accepted: 09/10/06 Abstract Sephardiellinae (nov. subfam.) encompasses a Middle Triassic Gondolleloid lineage that originated in the Sephardic realm, west- ernmost shallow Neotethys, from where, in the course of the Ladinian and earliest Carnian, some of its species spread to the world oceans, before extinction as a result of the Carnian salinity crisis. It is composed of two genera, Sephardiella and Pseudofurnishius. Differential criteria in its septimembrate apparatus are the basal cavity structure of P1 element and morphological variations in the P2 and S3 elements. Keywords: Conodonts, Middle Triassic, Sephardiellinae, Sephardic Realm, Neotethys. Resumen La nueva subfamilia Sephardiellinae está comprendida dentro del linaje de Gondolellidae del Triásico Medio y se originó en el Dominio Sefardí, la parte más occidental del Neotetis. Durante el Ladiniense-Carniense Inferior, algunas de sus especies irradian y se distribuyen por todos los océanos. Su extinción está relacionada con la crisis de salinidad que tuvo lugar en el Carniense. La nueva subfamilia está constituida por dos géneros, Sephardiella y Pseudofurnishius las diferencias morfológicas de su aparato sep- timembrado, como son la estructura de la cavidad basal del elemento P1 y las variaciones morfológicas de los elementos P2 y S3, constituyen el criterio utilizado. -
Die Conodontengattung Metapolygnathus HAYASHI 1968 Und Ihr Stratigraphischer Wert

Some species of Metapolygnathus are described. Some remarks to the chronology of the Upper Triassic are given. ) Anschrift des Verfassers: Dipl. Geol. Dr. Heinz Kozur, Staatliche Museen, Schloß Elisabethenburg, DDR-61 Meiningen Die Arbeit: "Die Conodontengattung Metapolygnathus HAYASHI 1968 und ihr stratigraphischer Wert" mußte aus drucktechnischen Gründen in drei Teile untergliedert werden. Die Beschreibung der neuen Art, sowie die stratigraphischen Schlußfolgerungen und die Tafeln wurden im Teil I (Geol. Paläont. Mitt. Innsbruck, 2, 11, 1972 a) veröffentlicht. Alle Angaben zu den Tafeln beziehen sich auf diese Arbeit. In der Trias treten mehrfach Homöomorphien zwischen Conodonten der verschiedensten Entwicklungsreihen auf, welche die taxonomische Bear- beitung erschweren und bei Nichtbeachtung zu stratigraphischen Fehlein- stufungen führen können. Bei den in der vorliegenden Arbeit untersuchten Entwicklungsreihen sind die Homöomorphien mitunter so stark, daß die End- oder Zwischenformen einzelner Entwicklungsreihen sich fast völlig gleichen. Die verwandtschaftlichen Beziehungen zwischen den einzelnen Arten der Gattung Metapolygnathus wurden bisher vielfach falsch gedeutet bzw. waren überhaupt nicht bekannt, wodurch -

The Pötschen Formation Is of Late Carnian (Tuvalian) to Early Rhaetian Age, As Demonstrated by the Presence of Conodonts (MOSTLER, 1978)
Berichte der Geologischen Bundesanstalt (ISSN 1017-8880), Band 111, Wien 2015 STRATI 2015 The Pötschen Formation is of Late Carnian (Tuvalian) to Early Rhaetian age, as demonstrated by the presence of conodonts (MOSTLER, 1978). The Pötschenhöhe ‘quarry’ exposes beds of Early Middle Norian age (= Alaunian 2, Himavatites hogarti Zone) dated by ammonoids (TATZREITER, 1985), redeposited as big gliding block in a late Norian matrix with Monotis salinaria (LK, unpublished). 3.1.3. Locality 2 – Großer Zlambach The Großer and Kleiner Zlambach are distributaries of the Traun River and name-giving for the Rhaetian Zlambach Formation. Though the formation displays an at least 150 m thick deep-marine succession, continuous sections are rare, due to common weathering of the soft sediments and a strong tectonic overprint with faults of unclear displacements making difficult a bed-by-bed correlation. The Kleiner Zlambach located north of the visited outcrop is the best exposed and less tectonised section but is unfortunately difficult to access (Fig. 9). Three closely neighbouring outcrops of the Großer Zlambach (Fig. 7; 47°37’47,5”N / 13°40’02,7”E) represent a partly folded and – though against each other fault bounded – lithologically complete Rhaetian sequence in far-reef basinal facies. The autochthonous background sedimentation of alternating marls and marly micritic limestone (Figs. 9 and 10) dominates here clearly the allochthonous carbonate sedimentation. An upward increasing thickness of the marls is characteristic for younger Rhaetian parts (Fig. 9). The allochthonous carbonate sedimentation consists of distal fine-grained turbidite, even if most of the beds do not show any characteristic turbiditic features.
