Permian sea
Sea levels have been determined for most of the Paleozoic Era (542 to 251 million years ago), but an integrated history of sea levels has remained unrealized. We reconstructed a history of sea-level fluctuations for the entire Paleozoic by using stratigraphic sections from pericratonic and cratonic basins. Evaluation of the timing and amplitude ...The Paleozoic era culminated 251.9 million years ago in the most severe mass extinction recorded in the geologic record. Known as the "great dying," this event saw the loss of up to 96% of all ...

4.4 Late permian: A closed terrestrial intra-cratonic basin in whole. At the end of Permian, the Southern Tianshan area was completely orogenic uplift with the shrinkage of the residual sea in the southwest Tianshan area (Carroll et al., 1995).

It ended with the greatest mass extinction known in the last 600 million years. Up to 90% of marine species disappeared from the fossil record, with many families, orders, and even classes becoming extinct. On land insects endured the greatest mass extinction of their history. The Zechstein ( German either from mine stone or tough stone) is a unit of sedimentary rock layers of Late Permian ( Lopingian) age located in the European Permian Basin which stretches from the east coast of England to northern Poland. The name Zechstein was formerly also used as a unit of time in the geologic timescale, but nowadays it is ... During the Pennsylvanian to Permian, sea levels began to fluctuate and ultimately fall. Regression of the sea was caused by a combination of glaciation at the South Pole and the forces of mountain building. Along the margins of the retreating sea, enormous coastal swamps formed.During the reef-building period, foraminifers covered thousands of miles of the ocean floor with lime (Rennicke 1985). A third abundant group of fossils in the Permian reef is echinoderms, such as crinoids (sea lilies) and echinoids (sea urchins). Echinoderms are solitary, bottom- dwelling, marine organisms.
