Some Trace Fossils from the Subathu Rocks of Nilkanth, Pauri-Garhwal, Himalaya

Abstract

Some well-preserved star shaped, cylindrical, curved, horizontal and vertical burrow like structures in the green and purple coloured shales of the Subathu roch of Nilkanth are described. Most of these structures are mud-lined, smooth surfaced and have relatively low densities and localised occurrence. These structures recognised as trace fossil burrows of Thalassinoides, Palacophycus and Planolites. Possible Palaeoenvironments in which the trace making communities lived are indicated.
