| Abstract | The paper describes a rich variety of microfossilsobtained by maceration from the variegated shale of the Salt Range. The microflora includes severalkinds of spores, both winged and unwinged; few megaspore-like bodies; fragments of wood; andseveral cuticular pieces. The spores are mostlypteridophytic and coniferous, the cycadophyticgrains being rare. Among the large number ofcuticles considerable proportion are of the Bradyphyllum and Pagiophyllum type, indicating that coniferales were strongly represented in the flora. Others with sinuous epidermal cells and syndetocheil type of stomata, suggesting a Bennettitalean affinity, are least represented.The spores and pollen grains are described underNaumova's (1937) artificial system. New subgroupshave been proposed for spores and pollen grains which do not fit in any of the known subgroups. The microflora as a whole suggests a middle Jurassic age for the variegated shale. |
