Abstract

Attention is drawn to the occurrence of some algal and fungal remains from the Tura Formation of Garo Hills, Assam. The algal microplanktons comprise 7 genera with one species each. The genera Oligosphaeridium, Achomosphaera, Hystrichosphaera and Hystrichosphaeridium are well represented while the remaining genera are present in lesser frequencies. The fungal remains are represented by 8 genera and 10 species. One of the genera, viz. Cucurbitariaceites is new and is commonly found in the assemblage. The other genera that are commonly found are Parmathyrites, Phragmothyrites, Callimothallus and Notothyrites. Stratigraphical value of these remains, if any, will have to wait till the completion of successional studies now in progress.

The presence of algal microplanktons indicates a brackish-water environment of deposition.
