A lower Jurassic miospore assemblage from the variegated shale, Nammal Gorge, Salt Range (West Pakistan)

Abstract

Present communication deals mainly with the morphological and taxonomical revision of the miospores previously recorded and described by Sah (1955) from the variegated shale sample, collected from Nammal Gorge, Salt Range, W. Pakistan. Apart from its botanical considerations, the spore-pollen assemblage has also been chronologically valued. It has been concluded on the miospores evidence that the Variegated Stage is older than the Rajmahal Intertrappean Series.
