1. Estimating the Early Evolution of Brachiopods Using an Integrated Approach Combining Genomics and Fossils
Master-uppsats, Uppsala universitet/PaleobiologiSammanfattning : The Brachiopoda, a major group of the Lophotrochozoa, experienced a rapid early evolutionary diversification during the well-known Cambrian explosion and subsequently dominated the Palaeozoic benthos with its diversity and abundance. Even though the phylogeny of the Lophotrochozoa is still hotly debated, it is now known that the Brachiopoda are a monophyletic grouping. LÄS MER
2. Paleontology and Sedimentology of the Alum Shale Formation at Björnberget, Västerbotten County, Sweden
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : A new locality of the Alum Shale Formation at Björnberget, Västerbotten County, of the lower allochthon of the Caledonian front is described herein. Two new species of acrotretid brachiopods were found. Tingitanella vilhelminia n. sp. LÄS MER
3. Linguliform Brachiopods from the Middle Cambrian ‘Thick’ Stephen Formation at Odaray Mountain, Canadian Rocky Mountains
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The linguliform brachiopod fauna from the Stephen Formation have long been thought to be very species poor and only consist of a few genera, but new discoveries from lime-stone beds in the “thick” Stephen Formation shows that this is not the case. The species described herein, Kyrshabaktella cf. tatjanae and Ceratreta hansi sp. nov. LÄS MER
4. Upper Cambrian trilobite faunas and biostratigraphy at Kakeled on Kinnekulle, Västergötland, Sweden
Magister-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Upper Cambrian strata are well exposed in an old quarry at Kakeled on south-western Kinnekulle, south-central Sweden. The exposures consist of finely laminated alum shale with lenses and beds of dark grey limestone (stinkstone or orsten), and a few thin layers of sandstone. A 6. LÄS MER
