Abstract

The Lower Barakar flora of Raniganj Coalfield shows close affinity with the Karharbari flora. The venation pattern of different leaf genera and its evolutionary trends are discussed. Insect wings, insect-affected leaf and stem specimens are recorded. On the available evidences, the insect/plant relationship during the early phase of Glossopteris Flora is discussed.
