Palynology of the Kazanian stratotype section (Permian, Russia): palaeoenvironmental and palaeoclimatic implications

Abstract

Palynomorph assemblages reflect changes in land plant communities and are thus significant proxies to interpret palaeoenvironmental and palaeoclimatic changes. The Middle Permian of the East European Platform is crucial to the understanding of marine and non-marine palaeoclimate archives and interregional correlations of marine and non-marine successions, utilizing palaeoclimate signatures documented in the palynological record. New palynological data from the Kazanian stratotype section are presented and interpreted with respect to palaeoenvironment and palaeoclimate. This dataset will serve as a basis for ongoing studies on the type area of the Kazanian and the midPermian biodiversity patterns, preceding the end-Guadalupian crisis and the changes of the endPermian biotic diversification followed by the most severe extinction event in Earth's history at the Permian-Triassic boundary.

“…According to Utting (2001), it ranges to the top of the Wordian. It is also recorded in the Kazanian stratotype (Russia), ranging up to the lower/upper Kazanian sub-stage boundary (intra-Roadian) (Götz and Silantiev 2015). However, the stratotype area is situated much farther south.…”
