1. Silurian Carbonate Platforms of Gotland, Sweden - Archives of Local, Regional and Global Environmental Changes
Abstract : This thesis treats the Silurian carbonate platforms of Gotland, Sweden, which formed close to the equator within the East Baltic Basin. Three different time intervals, all involving changes in facies composition and structure of the platforms, have been studied; Late Homerian, latest Homerian ? earliest Gorstian, and late Ludfordian, respectively.

2. Climate influenced deposition on a low latitude Sheinwoodian carbonate ramp, Gotland, Sweden
Abstract : The Sheinwoodian succession of Gotland comprises the Högklint, Tofta and Hangvar Formations and most of the Slite Group. The succession consists of hierarchically ordered shallow marine depositional cycles, produced by orbitally forced climate changes. READ MORE

3. Reef biostromes and related facies from the Middle Silurian of Gotland, Sweden
Abstract : Reef biostromes and related facies from the upper part of Wenlock and from Ludlow were investigated in order to account for their formation, their palaeoecology and biology. In the Hemse Group of Ludlow age, all studied biostromes comprise a low diversity fauna where one or few species dominates. READ MORE

4. Stratigraphy and facies of Middle Silurian epicontinental carbonate platform deposits of Gotland, Sweden
Abstract : The Silurian foreland of Scandinavia included a vast epicontinental carbonate platform system of which the island of Gotland (Sweden) is an erosional remnant. This thesis treats the Late Wenlock succession (Cyrtograptus lundgreni, Pristiograptus dubius parvus, Gothograptus nassa, Colonograptus(?) praedeubeli, and the Co(?) deubeli zones), and emphasises the sedimentology and biostratigraphy of these deposits.

5. Early Palaeozoic jawed polychaetes with focus on polychaetaspids and ramphoprionids from the Silurian of Gotland, Sweden
Abstract : Jawed polychaete annelid worms were abundant and diverse in the early Palaeozoic seas and their jaws (scolecodonts) are common microfossils in sedimentary rocks of that age. Despite their abundance, relatively little work has been focused on these fossils. READ MORE
