1. Palaeoenvironments of the Earliest (Middle Devonian) Tetrapod Trackways from the Holy Cross Mountains, Poland; Locomotion in a Terrestrial Setting?
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The palaeoenvironment from which early tetrapods emerged is crucial to comprehend in order to understand the mechanisms that drove and allowed the terrestrialization of vertebrates; one of the most important evolutionary ‘events’ in the history of animals. Nevertheless, much of the terrestrialization is shrouded in obscurity, inter alia, due to scarcity of early tetrapods in the fossil record. LÄS MER
2. An Early Jurassic conifer-dominated assemblage of the Clarence-Moreton Basin, eastern Australia
Magister-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : During the early Mesozoic two mass-extinction events profoundly reshaped the world’s biota. The first of these took place at the end of the Triassic and affected both marine organisms and terrestrial floras. The second occurred as an oceanic anoxic event during the early Toarcian. LÄS MER
3. Trace fossils from the Permian of western Dronning Maud Land, Antarctica
Magister-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Non-marine trace fossils from the Permian of Antarctica are systematically described and possible depositional environments are discussed. The studied material derives from sedimentary sequences consisting mainly of sandstone and shale at Vestfjella and Kirwanveggen, western Dronning Maud Land. LÄS MER
4. Upper Triassic depositional environments at Lunnom, northwest Scania
Magister-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : The mid-Rhaetic sequence at Lunnom, with coal and kaolinitic clays, indicates partly deltaic environments affected by alluvial processes during humid conditions. Of special interest is a thin bed of sandstone with coarse, angular quartz grains. LÄS MER
