1. Trilobites from the Middle and Upper Ordovician Andersön Shale Formation in Jämtland and the equivalent Killeröd Formation in Skåne, Sweden
Sammanfattning : Trilobites from the Middle and Upper Ordovician Andersön Shale Formation in Jämtland, central Sweden, and the Middle Ordovician Killeröd Formation in Skåne (Scania), southern Sweden, are revised and discussed. These formations have several genera and a few species in common, e.g. LÄS MER
2. Upper middle Cambrian through Furongian of Scandinavia with focus on trilobites, paleoenvironments and correlations
Sammanfattning : This thesis is based on studies of upper middle Cambrian through Furongian strata in Scandinavia with focus on trilobite biostratigraphy, taxonomy, paleoecology, and intercontinental correlation. The material studied derives mainly from Västergötland and Scania, southern Sweden. LÄS MER
3. Studies on Silurian trilobites from Gotland, Sweden
Sammanfattning : Trilobites of five families (Cheiruridae, Odontopleuridae, Encrinuridae, Phacopidae and Dalmanitidae) are described from the Silurian of Gotland. Fifty-five species (fourty-four named, of which twenty are new) are assigned to seventeen genera, of which Radiurus is new. LÄS MER
4. Evolution and taxonomy of Cambrian arthropods from Greenland and Sweden
Sammanfattning : Arthropods have a rich fossil record spanning the Phanerozoic. Biomineralized forms such as the extinct trilobites are particularly common and are proven index fossils for biostratigraphy. Forms with an unmineralized cuticle are more rare, preserved only in so called konservat lagerstätten. LÄS MER
5. The Cambrian lophotrochozoans of the Transantarctic Mountains, Antarctica
Sammanfattning : The origin of many lophotrochozoan groups can be traced to “small shelly fossil” (SSF) faunas of the Early Cambrian. Antarctica is a key region of study, due to the continent’s known close geographical proximity to well-studied Australian and Indian basins in in the Cambrian. LÄS MER
