  1. 1. Morphometric analysis of Cambrian fossils and its evolutionary significance

    Author : Illiam Jackson; Graham Budd; Jorijntje Henderiks; Richard Mann; Nigel Hughes; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Extended Evolutionary Synthesis; phenotypic plasticity; genetic assimilation; phenotypic accommodation; Agnostus pisiformis; Mackinnonia; elliptical fourier analysis; species concept;

    Abstract : The Extended Evolutionary Synthesis (EES) is currently emerging as a theoretical alternative to the Modern Synthesis (MS) in which to frame evolutionary observations and interpretations. These alternative frameworks differ fundamentally in their understanding of the relative roles of the genotype, phenotype, development and environment in evolutionary processes and patterns.

  3. 3. The lower and middle Cambrian of Sweden: trilobites, biostratigraphy and intercontinental correlation

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sedimentologi; Paleontologi; Palaeontology; fysisk geografi; Geologi; physical geography; Geology; Sweden; correlation; trilobites; biostratigraphy; Cambrian; Sedimentology;

    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
