  2. 1. Biostratigraphy and Systematics of Cambrian Small Shelly Fossils from East Antarctica and South Australia

    Author : Thomas M. Claybourn; Lars E. Holmer; Glenn A. Brock; Christian B. Skovsted; Graham Budd; David Harper; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cambrian; Biostratigraphy; Systematics; East Antarctica; Small Shelly Fossils;

    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. 2. Cambrian Series 2 (Stages 3-4) Small Shelly Fossils from East Antarctica

    Author : Thomas Claybourn; Lars Holmer; Christian Skovsted; Glenn Brock; Graham Budd; Jan Ove Ebbestad; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : An assemblage of Cambrian Series 2, Stages 3-4 small shelly fossils has been recovered from the Shackleton Limestone and Holyoake Formations of East Antarctica. Small shelly fossils from the early Cambrian are an important window into the world of Cambrian palaeobiology, biostratigraphy and biogeography. READ MORE

  5. 3. The Early Cambrian Fauna of North-East Greenland

    Author : Christian B. Skovsted; John S. Peel; Lars E. Holmer; Gerd Geyer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Early Cambrian; Dyeran; Botoman; Biostratigraphy; Palaeogeography; Small Shelly Fossils; Brachiopoda; Mollusca; Hyolitha; Trilobita; Geovetenskap; Earth sciences; Geovetenskap;

    Abstract : Small shelly fossils are common in sediments of Early Cambrian age and include the earliest common representatives of metazoan animals with mineralized hard parts. The group includes fossils of very different morphology, composition and ultrastructure. READ MORE

  6. 4. The Cambrian lophotrochozoans of the Transantarctic Mountains, Antarctica

    Author : Lewis Bassett-Butt; Lars Holmer; Glenn Brock; Christian Skovsted; Jan Ove Ebbestad; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Brachiopoda; Dailyatia; Cambrian; Drumian; Middle Cambrian; Early Cambrian; Antarctica; tommotiid; camenellan; palaeobiology; small shelly fossils; Earth Science with specialization in Historical Geology and Palaeontology; Geovetenskap med inriktning mot historisk geologi och paleontologi;

    Abstract : 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. READ MORE

  7. 5. Exceptionally Preserved Cambrian Lophotrochozoa : Taxonomy, Systematics and Taphonomy of Chengjiang and Indian Springs Lophophorates

    Author : Aodhán D. Butler; Michael Streng; Lars E. Holmer; Christian Skovsted; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Brachiopoda; Chengjiang; Lagerstätte; Cambrian Explosion; palaeobiology; stem-group; entoproct; phoronid; tommotiid; exceptional preservation.; Earth Science with specialization in Historical Geology and Palaeontology; Geovetenskap med inriktning mot historisk geologi och paleontologi;

    Abstract : The origin and evolution of Lophotrochozoa can be traced to the plethora of lower Cambrian scleritome taxa.  We aim to determine the character suites linking these stem-Lophotrochozoa to their extant crown relatives, in particular the small shelly tommotiids and the stem-group brachiopods.
