Some connection between the Cathaysian flora and the Glossopteris flora in India during the Later Permian age

Abstract

The Taiyuan (C3 + Po), the Shansi (F1/1+F1/2) and the Shihhotse (P1/2) including the Shihchienfeng (P2/2) series are roughly correlated to the Talchir (including the Boulder Bed), the Barakar (including the Karharbari and possiblY the Barren Measure), and the Raniganj series in India. respectively. The respective floras of each series of Cathaysia and Jndia are compared with each other epoch by epoch. It is concluded that the Cathaysian flora had almost nothing to do with the Glossopteris flora in India during the age ranging from the Taiyuan to the Shansi epoch, while during the mid-Permian crustal movements some elements of the Glossopteris flora as Schizoneura, Rhipidopsis, Glossopteris, and possibly Palaeovittaria came into contact and mixed with the Upper Permian Cathaysian flora.
