6. A geophysical investigation of carbonate build-ups in the Baltic Basin using reflection seismic and well data
Sammanfattning : During the Late Ordovician, the region around Gotland was part of a shallow epicratonic basin in the southern subtropics. Low latitudes, relatively warm sea temperatures and the presence of a shallow marine environment promoted algae to flourish and diverse carbonate build-ups such as carbonate mounds and reefs developed on the southern margin of Baltica.

7. Palaeobiology and diversification of Proterozoic-Cambrian photosynthetic eukaryotes
Sammanfattning : One of the most important events in the history of life is the evolution of the complex, eukaryotic cell. The eukaryotes are complex organisms with membrane-bound intracellular structures, and they include a variety of both single-celled and multicellular organisms: plants, animals, fungi and various protists.

8. Early Palaeozoic jawed polychaetes with focus on polychaetaspids and ramphoprionids from the Silurian of Gotland, Sweden
Sammanfattning : Jawed polychaete annelid worms were abundant and diverse in the early Palaeozoic seas and their jaws (scolecodonts) are common microfossils in sedimentary rocks of that age. Despite their abundance, relatively little work has been focused on these fossils. LÄS MER
9. Middle ordovician conodonts from the Atlantic faunal region and the evolution of key conodont genera
Sammanfattning : This thesis consists of seven separate articles that are mainly concerned with Middle Ordovician conodonts. The studied conodont specimens were obtained from three Middle Ordovician sections in south China and four Middle Ordovician sections in Sweden. LÄS MER
