Abstract

A plant megafossil assemblage comprising Cladophlebis sp., Pachypteris specifica Feistmantel, a fragmentary leaf, Ptilophyllum acutifolium Morris, Araucarites minutus Bose & Maheshwari, Elatocladus tenerrimus (feistmantel) Sahni, Brachyphyllum (Allocladus?) sp. Coniferocaulon rajmahalense Gupta. Coniferocaulon? sp. and roots, is reported from the coal bearing Puna Formation, Tingri District, southern Xizang, Tibet. This assemblage represents the assemblage Zone 9 (Sukh-Dev, 1988) of India and is considered Early Cretaceous in age. The similarity between the Puna florule and the Indian flora extends further the northern limits of Gondwanaland into southern Tibet.
