Biometric study of Plicatipollenites Lele and Potonieisporites Bhardwaj in the Lower Gondwana formations of the Hutar Coalfield, Bihar, India

Abstract

The data on the morphological trends of the Plicatipollenites/Potonieisporites populations worked out from Talchir to Barakar in the Hutar Basin are investigated. These trends are compared with the average picture obtained earlier from the synthesis of five basins. This study reveals that there is a reasonable degree of similarity between the morphological evolutionary trends of the Plicatipollenites/Potonieisporites populations of the Hutar basin and those obtained in the synthesis from the five Lower Gondwana basins by Lele and Shukla.
