By James W. Collinson (auth.), Thomas N. Taylor, Edith L. Taylor (eds.)

Antarctic Paleobiology discusses the present prestige of paleobiology, largely paleobotany and palynology in Antarctica, and the interrelationship of Antarctic floras to these of different Gondwana continents. It presents a extensive insurance of the main teams of vegetation at the one hand, whereas at the different looking to overview the vegetational heritage and the actual and organic parameters that impact the distribution of floras via time and house. The biologic job is mentioned inside a framework of the geologic historical past, together with the tectonic and paleogeographic historical past of the area. eventually, the reader will discover a accomplished bibliography of Gondwana paleobotany and palynology.

318) stated that Australia's position is essentially insensitive to the new poles, in fact the rotation of Gondwana would eliminate the paleogeographic conditions required to maintain aridity in that part of Gondwana. 3. As Van der Voo (1988) pointed out, the new pole position requires a hairpin movement of the continent at "rapid" drift rates; these rates are conservatively estimated to be at least 61 cmiyr (a minimum of 8000 km from the Middle-Upper Ordovician pole to the "middle" Silurian pole, over a minimum of 13 my, that is, from the end of the Ordoviciah to the beginning of the "middle" Silurian), an order of magnitude greater than any present drift rate.
