On a fossil wood from the Daru Formation (Permian) of Arunachal Pradesh, India

Abstract

The paper records for the first time a silicified fossil wood from the Garu Formation (Early Permian) exposed in Arunachal Pradesh. The wood is characterised by the presence of distinct growth zones, endarch primary xylem and a single, large, circular to oval, irregularly oriented pit in the cross-field; these features are diagnostic of the genus Megaporoxylon. As the wood does not match with any of the known species of the genus, it is given a new name, Megaporoxylon maheshwarii sp. nov.
