Correlation of Visean Floral Successions from the Equatorial Belt

摘要

Elucidation of the most important evolutionary events, which involve the largest regional floras in the major climatic belts of the Earth, is useful for interregional correlation based on megafossil remains. These events are reflected in synchronous directed changes in the major plant groups (divisions and classes). The establishment of such a change in the development of terrestrial floras of the equatorial belt in the mid-Visean allowed us to divide their Visean history into two stages (early and late Visean). We revealed that different parts of the belt are characterized by specific evolutionary changes. The character of middle Visean floral changes from different regions of the East European Platform is considered in. The present communication reports the results of a more detailed analysis of Visean floral successions from the equatorial belt.
