Here we studied new fossil chondrichthyans from two localities, Río de Las Minas, and Sierra Dorotea, both in the Magallanes Region, southernmost Chile. In Río de Las Minas, the upper section of the Priabonian Loreto Formation have yielded material referable to the taxa Megascyliorhinus sp., Pristiophorus sp., Rhinoptera sp., and Callorhinchus sp. In Sierra Dorotea, middle-to-late Eocene levels of the Río Turbio Formation have provided teeth referable to the taxa Striatolamia macrota (Agassiz), Palaeohypotodus rutoti (Winkler), Squalus aff. weltoni Long, Carcharias sp., Paraorthacodus sp., Rhinoptera sp., and indeterminate Myliobatids. These new records show the presence of common chondrichtyan diversity along most of the Magallanes Basin. The new record of Paraorthacodus sp. and P. rutoti, support the extension of their respective biochrons in the Magallanes Basin and likely in the southeastern Pacific.

(Chondrichthyes, Elasmobranchii) from the Middle Jurassic of SW Germany and NW Poland
Neoselachian remains (Chondrichthyes, Elasmobranchii) from the Middle Jurassic of SW Germany and NW Poland JÜRGEN KRIWET Kriwet, J. 2003. Neoselachian remains (Chondrichthyes, Elasmobranchii) from the Middle Jurassic of SW Germany and NW Poland. Acta Palaeontologica Polonica 48 (4): 583–594. New neoselachian remains from the Middle Jurassic of SW Germany and NW Poland are described. The locality of Weilen unter den Rinnen in SW Germany yielded only few orectolobiform teeth from the Aalenian representing at least one new genus and species, Folipistrix digitulus, which is assigned to the orectolobiforms and two additional orectolobi− form teeth of uncertain affinities. The tooth morphology of Folipistrix gen. nov. indicates a cutting dentition and suggests specialised feeding habits. Neoselachians from Bathonian and Callovian drill core samples from NW Poland produced numerous selachian remains. Most teeth are damaged and only the crown is preserved. Few identifiable teeth come from uppermost lower to lower middle Callovian samples. They include a new species, Synechodus prorogatus, and rare teeth attributed to Palaeobrachaelurus sp., Pseudospinax? sp., Protospinax cf. annectans Woodward, 1919, two additional but unidentifiable Protospinax spp. and Squalogaleus sp. Scyliorhinids are represented only by few isolated tooth crowns. No batoid remains have been recovered. The two assemblages contribute to the knowledge about early neoselachian distribution and diversity. Key words: Chondrichthyes, Neoselachii, Jurassic, Germany, Poland, taxonomy, diversity.

Taxonomic evidence places the first neoselachian diversification in the Early Jurassic. Taxonomic diversity analyses, however, are often affected by incompleteness of the fossil record and sampling biases. On the other hand, the range of morphological variation (disparity) offers a different perspective for studying evolutionary patterns across time. Disparity analyses are much more resilient to sampling biases than diversity analyses, and disparity has the potential to provide a more ecologically-relevant context. -
Thermal and Tectonic History of the Barrandian Lower Paleozoic, Czech Republic: Is There a Fission-Track Evidence for Carbonifer
Bulletin of Geosciences, Vol. 79, No. 2, 107–112, 2004 © Czech Geological Survey, ISSN 1214-1119 Thermal and tectonic history of the Barrandian Lower Paleozoic, Czech Republic: Is there a fission-track evidence for Carboniferous-Permian overburden and pre-Westphalian alpinotype thrusting?

E-mail: [email protected] 2 Varis RD, a. s., Na Výšině 11/1474, 143 00 Praha 4, Czech Republic. E-mail: [email protected] Abstract. Close scrutiny of apatite fission-track data from Barrandian Lower Paleozoic rocks shows that previous interpretations involving a late Car- boniferous to Permian heating stage and the extensive development of pre-Westphalian thrust tectonics are largely speculative. An alternative time-tem- perature path for the Barrandian sequence based on firmly established geological constraints and an improved version of the AFTSolve annealing kinetic model by Ketcham et al. (2000) is presented as evidence of a simple late Devonian to early Carboniferous Variscan peak heating, followed by a gradual Mesozoic to Tertiary cooling. Key words: apatite fission-track analysis, Barrandian, Variscan Orogeny, Lower Paleozoic Introduction ation has created a unique opportunity for critically com- paring two different annealing models now widely used for Glasmacher et al.

Neoselachians from the Danian (Early Paleocene) of Denmark
Neoselachians from the Danian (early Paleocene) of Denmark JAN S. ADOLFSSEN and DAVID J. WARD Adolfssen, J.S. and Ward, D.J. 2015. Neoselachians from the Danian (early Paleocene) of Denmark. Acta Palaeonto- logica Polonica 60 (2): 313–338. A diverse elasmobranch fauna was collected from the early Danian Rødvig Formation and the early to middle Danian Stevns Klint Formation at Stevns Klint and from the middle Danian Faxe Formation at Faxe, Denmark. Teeth from 27 species of sharks are described including the earliest records of Chlamydoselachus and Heptranchias howelli from Europe. The fauna collected at the Faxe quarry is rich in large species of shark including Sphenodus lundgreni and Cretalamna appendiculata and includes no fewer than four species of Hexanchiformes. The species collected yield an interesting insight into shark diversity in the Boreal Sea during the earliest Paleogene. The early Danian fauna recorded from the Cerithium Limestone represents an impoverished Maastrichtian fauna, whereas the fauna found in the slightly younger bryozoan limestone is representative of a pronounced cold water fauna. Several species that hitherto have only been known from the Late Cretaceous have been identified, clearly indicating that the K–T boundary was not the end of the Cretaceous fauna; it lingered and survived into the early Danian.

Email: [email protected] urn:lsid:zoobank.org:author:55EA63EE-63FD-49E6-A216-A6D2BEB91B82 Abstract. The family-group names of animals (superfamily, family, subfamily, supertribe, tribe and subtribe) are regulated by the International Code of Zoological Nomenclature. Particularly, the family names are very important, because they are among the most widely used of all technical animal names. A uniform name and spelling are essential for the location of information. To facilitate this, a list of family- group names for fossil fishes has been compiled. I use the concept ‘Fishes’ in the usual sense, i.e., starting with the Agnatha up to the †Osteolepidiformes. All the family-group names proposed for fossil fishes found to date are listed, together with their author(s) and year of publication. The main goal of the list is to contribute to the usage of the correct family-group names for fossil fishes with a uniform spelling and to list the author(s) and date of those names. No valid family-group name description could be located for the following family-group names currently in usage: †Brindabellaspidae, †Diabolepididae, †Dorsetichthyidae, †Erichalcidae, †Holodipteridae, †Kentuckiidae, †Lepidaspididae, †Loganelliidae and †Pituriaspididae.

Holtz Termin der Prüfung: 13.07.2001 Für Katrin, Frederick und Philipp V Kurzfassung Mergelproben aus dem Oberjura von Norddeutschland und Nordfrankreich (Boulonnais) haben ca. 20.000 systematisierbare Mikrovertebratenreste erbracht, die 58 Taxa von Elasmobranchiern und Actinopterygiern zugeordnet werden konnten. Die daraus resultierenden Faunenlisten für die einzelnen Zeitabschnitte des norddeutschen Oberjura und die beiden Faziestypen der nordfranzösischen Proben (normalmarine und brackische Faunen) weisen eine Vielzahl von Taxa erstmalig aus. In den Faunenzusammensetzungen von zahnreichen Probenschichten machen sich deutliche Unterschiede zwischen solchen aus normalmarinen (euhalinen) und solchen aus nicht-normalmarinen (hypo- bzw. hypersalinen) Lebensräumen bemerkbar. Dies ist in erster Linie auf die Menge und Zusammensetzung des Elasmobranchier-Anteils zurückzuführen, wohingegen die Actinopterygier-Anteile sich wohl eher aufgrund wechselnder Nahrungsangebote ändern.

Keuper (Late Triassic) Sediments in Germany 193
NORWEGIAN JOURNAL OF GEOLOGY Keuper (Late Triassic) sediments in Germany 193 Keuper (Late Triassic) sediments in Germany – indicators of rapid uplift of Caledonian rocks in southern Norway Josef Paul, Klaus Wemmer and Florian Wetzel Paul, J., Wemmer, K. & Wetzel, F. 2009: Keuper (Late Triassic) sediments in Germany – indicators of rapid uplift of Caledonian rocks in southern Norway. Norwegian Journal of Geology, vol. 89, pp 193-202, Trondheim 2009, ISSN 029-196X. K/Ar ages of detrital Keuper micas in the Central European Basin provide new information about the provenance of siliciclastic sediments. All sam- ples of the Erfurt Formation (Lower Keuper) and the Stuttgart Formation (Middle Keuper) indicate Caledonian (445 - 388 Ma) ages. These sedi- ments originate from the Caledonides of southern Norway. The older Fennoscandian Shield and the Russian Platform did not supply any material. In combination with zircon fission track data, we show that uplift of the Caledonides of southern Norway accelerated dramatically during the Car- nian, most likely as a result of rifting of the Viking Graben. This push of Scandinavian-derived sediments ceased in the Upper Keuper (Rhaetian). Instead of Scandinavian sediments, micas of Panafrican age were transported from southeast Poland and Slovakia into the Central European Basin. Only micas in the vicinity of the south German Vindelician High and the Bohemian Block have Variscan ages. J. Paul, K. Wemmer, F. Wetzel: Geowiss.

A preliminary für die Wegener-Störung postuliert. inverse FT thermal model for a Cambrian (Archer Fiord Formation) sandstone in the hanging wall of the Rawlings Bay thrust at Cape Lawrence is consistent with Paleocene exhumational cooling, likely as a result of erosion of the thrust. This suggests that thrusting at Cape Lawrence occurred prior to the INTRODUCTION onset of Eocene compression, likely due to transpression during earlier strike- slip along the strait.
