WOOD OF BURSEROXYLON FOSSIL FROM BARA FORMATION OF RANI KOT FORT AREA, DISTRICT JAMSHORO SINDH, PAKISTAN

Abstract

The paper describes a fossil wood identifiable as Burseroxylon baranesis from Bara formation of Sindh, Pakistan. Three dimension sections (transverse, radial and tangential) were prepared from the fossil wood collected from Bara formation, Ranikot. The anatomical characters such as presence of growth rings, parenchyma scanty, paratracheal, vasicentric. Rays are homogenous rays consist of procumbent cells indicate that the species belong to the family Burseraceae of petrified Bursera wood and are assigned name as Burseroxylon on the basis of form genus. This is the first record of genus Burseroxylon from tertiary rocks of Pakistan. Presence of diffuse porous wood indicate that the plants were growing in tropical type of climate.
