  1. 1. The morphology and evolutionary significance of the anomalocaridids

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Allison C. Daley; Graham E. Budd; Nigel C. Hughes; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; anomalocaridids; Cambrian; Burgess Shale; exceptional preservation; palaeontology; NATURAL SCIENCES Earth sciences Exogenous earth sciences Historical geology and palaeontology; NATURVETENSKAP Geovetenskap Exogen geovetenskap Historisk geologi och paleontologi; Historical Geology and Paleontology; Historisk geologi och paleontologi;

    Abstract : Approximately 600 to 500 million years ago, a major evolutionary radiation called the “Cambrian Explosion” gave rise to nearly all of the major animal phyla known today. This radiation is recorded by various fossil lagerstätten, such as the Burgess Shale in Canada, where soft-bodied animals are preserved in exquisite detail. READ MORE

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

    University dissertation from Department of Geology, Lund University

    Author : Niklas Axheimer; [2006]
    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

  3. 3. Endocranial Morphology and Phylogeny of Palaeozoic Gnathostomes (Jawed Vertebrates)

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Martin D. Brazeau; Per Ahlberg; Graham Budd; Henning Blom; Michael Coates; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; systematics; palaeontology; anatomy; evolution; NATURAL SCIENCES Biology Organism biology; NATURVETENSKAP Biologi Organismbiologi;

    Abstract : Gnathostomes, or jawed vertebrates, make up the overwhelming majority of modern vertebrate diversity. Among living vertebrates, they comprise the chondrichthyans (“cartilaginous fishes” such as sharks, skates, rays, chimaeras) and the osteichthyans (“bony fishes” or bony vertebrates, inclusive of tetrapods).

  4. 4. Late Ordovician-Early Silurian facies development and stratigraphy of Jämtland, central Sweden

    University dissertation from Department of Geology, Lund University

    Author : Peter Dahlqvist; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biostratigraphy; Sedimentology; Stratigrafi; Stratigraphy; Paleontologi; Palaeontology; Jämtland; provenance; brachiopods; conodonts; Hirnantian; Silurian; Ordovician; glaciation; eustasy; Sedimentologi; sedimentology;

    Abstract : This thesis is based on studies of Lower Palaeozoic sedimentary successions within the central Scandinavian Caledonides. These deposits have been transported by considerable nappe displacement (several kilometres), and are today relatively isolated from the nearest coeval outcrops (Dalarna 250 km, Oslo Region 350 km).

  5. 5. Middle and Upper Ordovician graptolites, trilobites, and biostratigraphy of Scania and Jämtland, Sweden

    University dissertation from Department of Geology, Lund University

    Author : Christian Pålsson; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; physical geography; Geology; Sweden; Jämtland; Scania Skåne ; Upper Ordovician; Middle Ordovician; palaeoecology; biostratigraphy; lithostratigraphy; Graptolites; trilobites; Geologi; fysisk geografi; Palaeontology; Paleontologi;

    Abstract : Graptolites and some trilobites from Middle–Upper Ordovician siliciclastic and calcareous rocks in Scania (Skåne), southern Sweden, and Jämtland, central Sweden, are described and discussed. Their stratigraphic distribution is discussed on the basis of new and old collections from outcrops and drill cores. READ MORE
