We know that there were great paleoclimatic changes during the Pennsylvanian and Permian. the Pennsylvanian in Euramerica is characterized by great peat (coal) swamps, widespread changes in sea level occurred during the Pennsylvanian, continental glaciation during both periods, and great aridity particularly in the Permian.
Hi Paul,
just a short comment. We are faced to the same questions working mainly in the Lower Permian. Regarding palaeoclimate we try to follow three different lines of evidence, (1) characterisation of the palaeosol and its components, geochemical proxies, precipitation proxies, (2) characterisation of the in-situ plants (growth interruptions in woody tissues and their cyclicity patterns), (3) characterisation of the in-situ plant roots and their habit adaptations. The sum will result in a more reliable picture of the environmental conditions, but I know we can trust because our fossil Lagerstätte is a T0 assemblage. A manuscript is in progress, hope it will come out soon in PPP. Of course, an adequate stratigraphic control is necessary for any comparisons to other regions or basins.
All the best
Ronny
Hi Ronny, This is a very astute answwer.I give you a thumps up on your answer. Best wishes, Paul.
Dear Peter,
Thank your for the references that I will read with great iinterest. Appreciate your iinput. Paul.
