Sytematics, palaeoecology and trophical structure of bivalve associations within the OAE2 in the Bohemian Cretaceous Basin (Upper Cenomanian): Pecínov quarry

Title: Sytematics, palaeoecology and trophical structure of bivalve associations within the OAE2 in the Bohemian Cretaceous Basin (Upper Cenomanian): Pecínov quarry Author: Bc. Lucie Kunstmüllerová Department: Institute of geology and palaeontology Supervisor: doc. RNDr. Martin Košťák, Ph.D. Abstract: This master thesis provides an updated taxonomic inventory of the bivalve fauna of the Pecínov locality, places the fauna in its palaeobiogeographic setting, and addresses its palaeoecological significance. In the literature research part of the thesis the basic geology of the locality and an overview of the Bohemian Cretaceous Basin are presented. Processes connected to the ocean anoxic events, specifically to the OAE 2 are also discussed. The research part of the thesis describes the systematics of the bivalve assemblage (with the exception of Inoceramidae) and its statistical evaluation with the emphasis on the environment interpretations of the locality. In total, over 350 specimens have been considered and assigned to 20 genera within 15 families and 9 orders. Bivalve functional morphology and guilds are described to interpret palaeoecology. Guilds are based on life habit and feeding category. Four main guilds are recognized: epifaunal suspension-feeders, semi-infaunal suspension-feeders, infaunal...

Title: Sedimentology and taphonomy of the Valeč locality, Oligocene. Author: Lucie Kunstmüllerová Department: Institute of geology and palaeontology Supervisor: Mgr. Karel Martínek, PhD. Consultant: RNDr. Martin Mazuch, Ph.D. Abstract: The literature research part of this bachelors thesis is devoted to an complex overview of the palaeontology and sedimentology of the Valeč locality. The following taxa of fauna were described from the locality: dormouse Bransatoglis micio, gastropods Limnaeus subpalustris thomae, cyprinids Varhostichthys brevis, Leuciscus colei a Chondrostroma stephani and pikes Esox walchanus. Floral assemblage comprise Mahonia sp., Rumohra sp., Eotrigonobalanus furcinervis, Almus rhenana, Quercus heerii, Platanus neptuni, Cinnamomum sp., Pinus ornata, Doliostrobus taxiformis, Podocarpus sp. a Tetraclinis salicornioides. The findings indicate the age after Grande Coupure event which marks the approximate age of 34 Ma (Oligocene). According to the CA analysis of the floral remains the climate was moderate and humid. The research part of the thesis included construction of the measured sedimentary section; the following sedimentary facies were distinguished: masive lapillistone with a sandy matrix (LM), cross bedded lapillistone (LSZ), lapillistone with clayey-sandy matrix (LJP), tuff (T),...
