Problems for Evaluation of the Scenario of the Permian -Triassic Boundary Biotic Crisis and of Its Causes	2010	28	.pdf	application/pdf	25317	1078	63	Abstract Determination of the causes o f the Permian -Triassic boundary (PTB) biotic crisis is hindered primarily by the diachronous nature of the used PTB, poor stratigraphic control of compared Upper Permian and Lower Triassic faunas, espec ially in cont inental biotopes, poor knowledge of the lower and midd le Scythian faunas from m,UlY envi­ ronments, and by interpolation of the unknown (lower and middle) Scythian diversity from the known Upper Pennian and Middle Trias­ sic diversity data in many major fossil gro ups. On the basis of the real (not interpolatcd) ext inction and recovery patterns of the major fossil groups, and with consideration of the geological phe­ nomena in the Upper Permian and Lower Triassic, a possible scenario for the PTE biotic crisis is presented.	cache/gc-283.pdf	txt/gc-283.txt
