Introduction The Upper part of the Jurassic sequence in southern Germany is named the "White Jurassic" due to the light colour of its rocks. It does not correspond exactly to the Upper Jurassic as defined by the International Colloquium on the Jurassic System in Luxembourg (1962), because the lower Oxfordian is included in the "Brown Jurassic", and because the upper Tithonian is missing. The White Jurassic covers more than 10 000 square kilometers between the upper Main river near Staffelstein in northern Bavaria and the Swiss border west of the lake of Konstanz. It builds up the Swabian and the Franconian Alb. Because the Upper Jurassic consists mainly of light limestones and calcareous marls which are more resistent to the erosion than the clays and marls of the underlying Brown (middle) Jurassic it forms a steep escarpment directed to the west and northwest. To the south the White Jurassic dips below the Tertiary beds of the Molasse trough. -

The preserved teeth display distinctive features such as a very long, robust and coarsely Lower jurassic infolded roots; as well as low, labio-lingually compressed, large triangular crowns with carinae. Dental features south Pangea are consistent with those of the genus Temnodontosaurus, previously known in the Lower Jurassic of Europe. This Paleobiogeography find represent the first record of a temnodontosaurid ichthyosaur in the southern hemisphere, reinforcing a pattern of faunal interchange between the northern Tethys and southern Panthalassa, prior to the separation of Palabras clave: Laurasia and Gondwana, and before the full establishment of the Caribbean Seway.

En el presente trabajo se reporta por primera vez una fauna de amonites (Paltechioceras cf. mexicanum, P. rothpletzi, Ortechioceras incaguasiense, Coroniceras? (Metophioceras) aff. conybeari auct., Phylloceras sp., Sulciferites? cf. stenorhynchus) e isocrínidos bentónicos (Isocrinidae) y pseudoplanctónicos (Pentacrinitidae). Estos últimos representan nuevos registros para sedimentos sinemurianos de México. Se consideran los supuestos hábitos de vida para las familias a las que pertenecen las especies de amonites, como dato de referencia sobre el ambiente de depósito. En este afloramiento también se encuentra el bivalvo Posidontis semiplicata y un gasterópodo no identificado. Hay tres tipos de asociaciones fósiles que se encuentran repetidamente en las capas del afloramiento Temapá, perteneciente a la Formación Despí, de tal forma que es posible reconocerlas (1) por la diferencia de diámetro de los amonites que las componen; (2) por la diferente composición faunística entre ellas, que se demuestra con la aplicación del índice de Simpson; y (3) por el grado de fragmentación de las conchas. -

Tomáš Kumpan, Ph.D. Year: 2020 Number of Pages: 70+15 Keywords: Bohemian Massif, Callovian, Oxfordian, ammonites, taxonomy, biostratigraphy, provincialism, paleogeography Abstrakt Diplomová práce je zaměřena na taxonomickou revizi středně a pozdně jurských (callov-oxford) amonitů (Ammonitida), skupinu vymřelých hlavonožců z řad amonoidů (Ammonoidea). Studováni byli především amoniti z jurských vápenců na lokalitách Brno-Hády a Olomučany. Přesné stáří jurských vrstev na těchto lokalitách, především v měřítku amonitových zón a subzón, nebylo doposud jednoznačně určeno. Vzhledem k tomu, že amoniti z těchto lokalit byli zpracovávaní naposledy před mnoha dekádami a poznání jejich taxonomie a biostratigrafie vyznamně pokročilo, vyvstala potřeba provést revizi. Na předešlé výzkumy bylo navázáno moderním zpracováním amonitů zohledňujícím vnitrodruhovou variaci a sexuální dimorfismus. Soubor studovaných amonitů je tvořen z části historickými nálezy uloženými v univerzitních a muzejních sbírkách a z části soudobými nálezy autora, jeho kolegů a místních sběratelů. -
