3. 2. Late Devonian vertebrates from Siberia: a synchrotron microtomography study of bone bed material

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Étienne Fortier-Dubois; [2016]
   Keywords : Siberia; Late Devonian; Megistolepis; paleontology; microtomography; vertebrates; synchrotron; stem tetrapods; fossil;

   Abstract : This is an investigation of new vertebrate fossil material from the Late Devonian locality of Ivanovka, Uryup River, Siberia. This bone bed material, circa 375 million years in age, represents a unique opportunity to fill a gap in our understanding of Late Devonian diversity, biogeography, and vertebrate evolution: Siberia, at the time, was an independent continent, and yet its fauna remains virtually unknown in comparison with the other paleocontinents, Euramerica and Gondwana.
