1. The Origins and Ecology of Early Paleozoic Spreiten Ichnofossils: Comparisons of Daedalus and Syringomorpha with Alectorurus
Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The Cambrian explosion not only shaped the ecosystems of the Phanerozoic, but fundamentally changed how biota interacts with the environment, including the substrate. Cambrian trace fossils Alectorurus and Syringomorpha as well as Ordovician-Silurian Daedalus represent novel modes of faunal interaction with the newly innovated shallow marine mixed-ground and have surprisingly limited stratigraphic ranges.

3. Characterization of mineral parageneses and metamorphic textures in eclogite- to high-pressure granulite-facies marble at Allmenningen, Roan, western Norway
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : The Roan peninsula in western Norway, Vestranden, is known for exposing one of the deepest parts of the Scandinavian Caledonian orogen, similar to the Western Gneiss Region. Throughout the Roan area, eclogites and high-pressure granulite- and amphibolite-facies gneisses occur, associated with supracrustal rocks including marbles, calc-silicate rocks and amphibolites.

4. Enigmatic worm-like fossils from the Silurian Waukesha Lagerstätte, Wisconsin, USA
Kandidat-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : The lower Silurian Waukesha Lagerstätte of Wisconsin, USA, is a Konservat-Lagerstätte which has yielded a diverse assemblage of exceptionally well-preserved soft-bodied organisms. This study comprises first-hand descriptions and assessments of 23 enigmatic worm-like specimens from the Waukesha Lagerstätte, alongside a literature review. LÄS MER
5. Stratigraphy, sedimentology and geophysical assessment of the early Silurian Halla and Klinteberg formations, Altajme core, Gotland, Sweden
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : The Altajme drillcore was recovered from near Buttle in central Gotland in 2015. The core was drilled in outcrop belt of the late Wenlock (Silurian) Klinteberg Formation as a result from an international drilling campaign between the Department of Geology at Lund University and Iowa University, USA.
