Ichnology of the early cambriantal group, Nigalidhar syncline, lesser Himalaya, India

摘要

Though trace fossils have been recorded from the Tal Group of the Krol-Tal Belt by earlier workers, most of the records are at generic level only. This paper describes, in detail, 24 ichnospecies from 20 ichnogenera, some of which are being reported for the first time, from the Ganog and Koti Dhaman sections of the Nigalidhar Syncline, H.P. Based on the ichnostratigraphic and ichnofabric analyses these ichnofossils have been categorized into three ichnoassemblages, namely Palaeophycus-Phycodes, Daedalus-Phycodes, and Cruziana Ichnoassemblages. An attempt has also been made for correlation of the Tal sections with other Precambrian-Cambrian sections of the world.
