2. 6. Jurassic and Early Cretaceous selachians - focus on southern Scandinavia

   Author : Jan Rees; Berggrundsgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geology; Paleontologi; Palaeontology; Lissodus; palaeoecology; England; Denmark; Sweden; sharks; selachians; Jurassic; Early Cretaceous; physical geography; Geologi; fysisk geografi;

   Abstract : The Jurassic and Early Cretaceous selachian faunas of Scania (Skåne), southern Sweden and the island of Bornholm (Denmark) have been investigated. Three Early Jurassic shark tooth assemblages have been recorded and investigated, one from Hettangian strata and the other two from Pliensbachian sediments. READ MORE

   Abstract : In 1902, a Swedish professor at Shanxi University started to study the region’s geology and in 1913, he suggested to the Chinese Republican Government an expansion of these surveys nationwide. As a result, the Head of the Geological Survey of Sweden, J. G. Andersson, was employed as a geological adviser to the Chinese Government. READ MORE

5. 8. Upper middle Cambrian through Furongian of Scandinavia with focus on trilobites, paleoenvironments and correlations

   Author : Fredrik Terfelt; Berggrundsgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Paleontologi; Palaeontology; Scandinavia; Paleoenvironments; Biostratigraphy; Trilobites; Cambrian; Furongian;

   Abstract : This thesis is based on studies of upper middle Cambrian through Furongian strata in Scandinavia with focus on trilobite biostratigraphy, taxonomy, paleoecology, and intercontinental correlation. The material studied derives mainly from Västergötland and Scania, southern Sweden. READ MORE

6. 9. Molecular, micro- and ultrastructural investigations of labile tissues in deep time

   Author : Johan Gren; Berggrundsgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; eumelanin; fossils; histology; integument; IR microspectroscopy; melanin; melanosomes; molecular palaeontology; ToF-SIMS; XAS;

   Abstract : This thesis comprises investigations of microstructures and molecular remains, preserved in a variety of fossil specimens. The results are presented in six papers, collectively aiming to thoroughly examine fossil traces of such remains by employing a combination of both established and relatively new analytical methods.

7. 10. Exceptional fossil preservation: implications for palaeobiology and taphonomy

   Author : Miriam Heingård; Berggrundsgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; exceptional preservation; molecular palaeontology; palaeobiology; taphonomy; braincase; cuticle; fish larvae; Fur Formation; Stolleklint Clay; melanin; systematics;

   Abstract : Although fossils are relatively common in some sedimentary deposits, the majority consists of fragmented or distorted skeletal hard parts (such as shell and bones). However, in rare cases, special burial and diagenetic conditions have allowed a greater portion of the original anatomy to be incorporated into the fossil record. READ MORE
