The Locality of Fossil Plants Juldybaevo (Kungurian Stage, Lower Permian, Republic of Bashkortostan, Russia) and Its Position in the System of Kungurian Phytoorictocoenoses of the Eastern European Platform
摘要
The article is devoted to the characteristics of the Juldybaevo floristic assemblage of the Republic of Bashkortostan, Russian Federation. This assemblage has an Early Permian (Kungurian) age and includes a number of representatives of Permian spore and gymnosperm plants, which are characteristic of the Early Permian stage of the florogenesis of the Western Angaraland. The information about the regional geology and stratigraphy of the Cis-Uralian Foredeep is given. A detailed description of the Juldybaevo floristic assemblage is given. This assemblage includes representatives of the equisetophytes, pteridosperms (lyginopteridophytes), ginkgophytes, vojnovskyopsids, and conifers. The main trends in the evolution of the Early Permian floras of the Western Angaraland are analyzed. The authors’ ideas about the paleogeographic and paleoclimatic conditions of the Juldybaevo flora are presented.
