[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.

Licensed under the Creative Commons Attribution- NonCommercial-NoDerivatives 4.0 International http://creativecommons.org/ licenses/by-nc-nd/4.0/ 1 Abstract Permian strata from the Tieqiao section (Jiangnan Basin, South China) contain several distinctive conodont assemblages. Early Permian (Cisuralian) assemblages are dominated by the genera Sweetognathus, Pseudosweetognathus and Hindeodus with rare Neostreptognathodus and Gullodus. Gondolellids are absent until the end of the Kungurian stage—in contrast to many parts of the world where gondolellids and Neostreptognathodus are the dominant Kungurian conodonts. A conodont changeover is seen at Tieqiao and coincided with a rise of sea level in the late Kungurian to the early Roadian: the previously dominant sweetognathids were replaced by mesogondolellids.

Gonchar Str. 55-b, 01601 Kiev, Ukraine ___________________________________________________________________________ A major criterion for selecting a Global Stratotype Section and Point (GSSP) is to demonstrate depositional continuity. Depositional continuity is most often accepted where there is a transitional morphocline from an ancestral species to its descendent. The GSSP is then selected to correspond with the phylogenetic first occurrence of the descendent species. Ideally, strata elsewhere are subsequently correlated with the GSSP using the local first appearance of the descendent species, or by other taxa associated with the GSSP providing supplementary biostratigraphic data. Any other stratigraphic methods can be used for correlation once the GSSP has been ratified by the International Union of Geological Sciences Commission on Stratigraphy. Multiple conodont lineages with complete transitional morphologies characterize the Bashkirian- Moscovian boundary interval in the Naqing section. The presence of all these chronoclines through the section demonstrates depositional continuity at Naqing, and provides numerous possible conodont- based levels available for selecting a basal Moscovian GSSP.

[email protected] 2 Department of Geosciences, University of Padova, Via Giotto 1, Padova, I-35137. Pizzo Mondello (Sicani Mountains, Western Sicily, Italy) is one of the best sites for the study of the Carnian/Norian boundary and of Upper Triassic conodonts phylogenesis as well. Pizzo Mondello section is a 450 m thick continuous succession of pelagic-hemipelagic limestones (Calcari con selce or Halobia Limestone auctorum; Cherty Limestone, MUTTONI et al, 2001; 2004) consisting in evenly-bedded to nodular clacilutites (mostly mudstones/wackestones with radiolarians) rich in bivalves (Halobia) and ammonoids, with cherty lists and nodules (GUAIUMI et al., 2007; NICORA et al., 2007). Conodonts are very abundant giving the opportunity to observe and to point out clear relationships among the four most widespread Upper Carnian/Lower Norian conodont genera (Paragondolella, Carnepigondolella, Metapolygnathus and Epigondolella) and to identify trends of the genera turnovers. Genera have been classified and separated following the original diagnosis given by the Authors, regarding also as discriminating for the genera taxonomy the following morphological elements: position of the pit, with respect both to the platform and to the keel; shape of the keel end; length of the platform and occurrence of nodes and/or denticles on the platform margins.

  • Paleoenvironmental Interpretation and Identification
    PALEOENVIRONMENTAL INTERPRETATION AND IDENTIFICATION OF THE NORIAN – RHAETIAN BOUNDARY IN THE SINWA FORMATION (MOUNT SINWA, BRITISH COLUMBIA) USING STABLE ISOTOPES AND CONODONTS by JERRY (Z.X.) LEI A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF BACHELOR OF SCIENCE (HONOURS) in THE FACULTY OF SCIENCE Department of Earth, Ocean, and Atmospheric Sciences This thesis conforms to the required standard ……………………………………………………………………………………………………… Advisor Faculty Co-Advisor THE UNIVERSITY OF BRITISH COLUMBIA April 2018 ii Abstract The Sinwa Formation is exposed at its type locality on Mt. Sinwa, located in the southern portion of the Whitehorse Trough in northwestern British Columbia. Composed of thick, fossiliferous Late Triassic carbonates, the formation is interpreted to have been deposited in the forearc basin between the Stikine Terrane (pre-accretion) and the North American Craton. This study marks the first detailed stratigraphic investigation of the Sinwa Formation and has significant implications for understanding Late Triassic paleoenvironmental changes in the region and the location of the Norian-Rhaetian boundary in North America. It also contributes to ongoing research refining Late-Norian to Rhaetian conodont biostratigraphy. This was achieved by recording lithologies, δ13C, and conodonts across a 231.3 m thick section. Carbonate facies progress up-section from rip-up clast rich mudstone, to coral fragment wackestone, to bivalve coral wackestone/packstone and intact coral boundstone, to a dark siliciclastic shale. This progression is interpreted as rising sea level caused by local tectonics. Petrographic thin sections show variation in depositional energy based on matrix texture. Conodont species recovered include Mockina englandi, M. carinata, M. cf. spiculata, M.

  • Palaeoecology of Late Triassic Conodonts: Constraints from Oxygen Isotopes in Biogenic Apatite
    Palaeoecology of Late Triassic conodonts: Constraints from oxygen isotopes in biogenic apatite MANUEL RIGO and MICHAEL M. JOACHIMSKI Rigo, M. and Joachimski M.M. 2010. Palaeoecology of Late Triassic conodonts: Constraints from oxygen isotopes in biogenic apatite. Acta Palaeontologica Polonica 55 (3): 471–478. The oxygen isotopic composition of conodont apatite derived from the Late Triassic (Carnian to lower Norian), Pignola 2 and Sasso di Castalda sections in the Lagonegro Basin (Southern Apennines, Italy) was studied in order to constrain the habitat of Late Triassic conodont animals. Oxygen isotope ratios of conodonts range from 18.5 to 20.8‰ V−SMOW, which translate to palaeotemperatures ranging from 22 to 31°C, assuming a d18O of Triassic subtropical sea water of −0.12‰ V−SMOW. These warm temperatures, which are well comparable to those of modern subtropical−tropical oceans, along with the body features of the conodont animal suggest that conodont d18O values reflect surface water temperatures, that the studied conodont taxa lived in near−surface waters, and that d18O values of Late Triassic conodonts can be used for palaeoclimatic reconstructions. Key words: Conodonta, palaeoecology, oxygen isotope, palaeotemperatures, Late Triassic, Tethys.

Conodont biostratigraphy of a Carnian-Rhaetian succession at Csovár,˝ Hungary Viktor Karádi Department of Paleontology, Eötvös Loránd University, Budapest, Hungary ([email protected]) The global biozonation of Upper Triassic conodonts is a question still under debate. The GSSPs of the Carnian- Norian and Norian-Rhaetian boundaries are not yet defined, thus every new data contributes to the solution. In north-central Hungary the Csovár˝ borehole exposed a nearly 600 m thick Carnian-Rhaetian succession of cherty limestones and dolomites that represent toe-of-slope and basinal facies. The aim of this study was to give a detailed biostratigraphical analysis of the borehole material based on conodonts. Although the amount of the material was quite low (half kg/sample) a rich conodont fauna was found, 37 species of 9 genera could be identified. The iden- tified conodont zones and their main features are as follows: - Misikella ultima Zone (upper Rhaetian): appearance of M. ultima; - Misikella posthernsteini Zone (lower Rhaetian): appearance of M. posthernsteini, decrease in number of M. hern- steini; - Misikella hernsteini-Parvigondolella andrusovi Zone (upper Sevatian): appearance of Oncodella paucidentata and P. andrusovi, presence of M. hernsteini; - Mockina bidentata Zone (lower Sevatian): appearance of M. bidentata, diversification of genus Mockina, appear- ance of M. hernsteini; - Epigondolella triangularis-Norigondolella hallstattensis Zone (upper Lacian): appearance of advanced forms of E. triangularis, presence of E. uniformis; - Epigondolella rigoi Zone (middle Lacian): increase in number of E. rigoi, presence of advanced forms of E.

We propose new regional correlations of the Mersin mélanges with other mélange-like units or similar series, located both in southern Turkey and adjacent regions. The palaeotectonic implications of the correlations are also discussed. The main results may be summarized as follows: the infra-ophiolitic mélange is subdivided into two units, the Upper Cretaceous Sorgun ophiolitic mélange and the Ladinian−Carnian Hacialanı mélange. The Mersin mélanges, together with the Antalya and Mamonia domains, are represented by a series of exotic units now found south of the main Taurus range, and are characteristic of the South-Taurides Exotic Units.
