1. Evolution and ecology of Baltic late Ordovician univalved molluscs
Abstract : Univalved molluscs (Gastropoda and Tergomya) are common fossils in the Palaeozoic succession across Baltoscandia, but most of the more embracive descriptive works on this group appeared before or near the turn of the 19th century. The study presented here aims at revision and description of some Baltoscandian late Ordovician/early Silurian univalved molluscs with emphasis on their shell morphology. READ MORE

2. The Cambrian lophotrochozoans of the Transantarctic Mountains, Antarctica
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

3. Geology, stratigraphy, and fossil vertebrates of Gotland, Sweden : a review
Abstract : The Silurian limestones of Gotland, Sweden, and their exceptionally well-preserved fossils have attracted the interest of scientists for more than 200 years. The sedimentary rocks represent approximately 10 million years of time, and were deposited in a shallow, equatorial inland sea named the Baltic Basin. READ MORE

4. Cambrian Series 2 (Stages 3-4) Small Shelly Fossils from East Antarctica
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. Late Ordovician Faunal Distribution and Ecospace Partitioning in Marine Impact Craters : The Aftermath of the Lockne and Tvären Events
Abstract : In the Middle to Late Ordovician a boost of marine biodiversity occurred which is regarded as the most rapid diversity in Earth’s history, and termed the Great Ordovician Biodiversification Event. This time is also unique in that at least four marine meteorite craters with a good record of post-impact sediments are preserved in Baltoscandia. READ MORE
