TRACE FOSSILS FROM THE CAMBRIAN SEQUENCE OF ZANSKAR (LADAKH HIMALAYA)

Spiti - Zanskar Basin of Himalaya exposes rocks ranging in age from Pr oterozoic to Early Cenozoic. Cambrian trilobites, brachiopods and trac e fossils are known from the Kurgiakh area of the basin. The present p aper concerns with Early Cambrian trace fossils reported from the same stratigraphic section in which trilobite body fossils are known. The assemblage of trace fossils include : Chondrites sp., Cruziana sp., Ru sophycus sp., Phycodes palmatum, sp., Didymaulichnus sp., Protichnites sp., Monomorphicnus monolinearis, Diplichnites sp, associated with sc ratch marks indicating trilobite movements. The finding of trace fossi ls far below the definite brachiopod and trilobite body fossil horizon s in the Lower Cambrian sequence of Kurgiakh area of Zanskar is of sig nificance.
