1. Biostratigraphy and Systematics of Cambrian Small Shelly Fossils from East Antarctica and South Australia
Abstract : The remote lower Cambrian Byrd group of sedimentary rocks from East Antarctica has been studied intermittently since its discovery over a century ago. Previous insights into the trilobites and archaeocyaths indicated a close correlation to the sedimentary sequences of South Australia. READ MORE

4. The lower and middle Cambrian of Sweden: trilobites, biostratigraphy and intercontinental correlation
Abstract : This thesis is based on studies of Cambrian successions in Sweden, with particular focus on the middle Cambrian biostratigraphy and its correlative relationship to the proposed global agnostoid zonation. The investigated material, mainly trilobites, was collected from both outcrops and drill cores from five provinces in Sweden: Skåne (Scania), Öland, Västergötland, Jämtland and Lapland. READ MORE
