Correlation of Lopingian to Middle Triassic Palynozones


Nowak, Hendrik; Schneebeli-Hermann, Elke; Kustatscher, Evelyn (2018). Correlation of Lopingian to Middle Triassic Palynozones. Journal of Earth Science, 29(4):755-777.

Abstract

Terrestrial floras underwent important changes during the Lopingian (Late Permian), Early Triassic, and Middle Triassic, i.e., before, during, and after the end-Permian mass extinction. An accurate account of these developments requires reliable correlation. Macrofossils of land plants can only provide a low-resolution biostratigraphy, while detailed zonation schemes based on palynomorphs are available for many regions. Their applicability is still limited due to several factors, such as (micro-)floral provincialism, a lack of suitable marker taxa commonly occurring at important boundaries, and in many cases a lack of independent age control. Nevertheless, these palynostratigraphic schemes are regularly used for dating and correlation of successions between different regions. To support such efforts, the biozonation schemes based on palynomorphs from the Lopingian up to and including the Middle Triassic from across the world are summarized and revised. Thus, a consistent correlation of palynozones with the currently recognized international stages is established.
