11. Early–Middle Ordovician biotic and sedimentary dynamics in the Baltoscandian paleobasin
Sammanfattning : The Baltoscandian region forms part of the paleocontinent Baltica, which was largely covered by a shallow epeiric sea throughout much of the Ordovician (c. 485.5–444 Ma). This ancient sea is today recorded by a thin succession of sedimentary rocks. LÄS MER
12. A combined carbon and hydrogen isotope approach to reconstruct the SE Asian paleomonsoon : Impacts on the Angkor Civilization and links to paleolimnology
Sammanfattning : Changes in monsoon patterns not only affect ecosystems and societies but also the global climate system in terms of heat energy and humidity transfer from the equator to higher latitudes. However, understanding the mechanisms that drive monsoon variability on longer timescales remains a challenge, partly due to sparse paleoenvironmental and paleoclimatic data. LÄS MER
13. Early land plant spores from the Paleozoic of Sweden – taxonomy, stratigraphy and paleoenvironments
Sammanfattning : The Silurian through earliest Devonian, between ca 444 and 412 million years ago, was characterized by significant changes in global climate and environment. At that time, plants and animals had begun to expand the colonization of previous relatively desolate terrestrial landscape. LÄS MER
