Soft-Bodied Fossil Preservation in the Cambrian Parahio Formation of Spiti

Cases of soft part preservation, now known widely in Cambrian rocks throughout the world1, have resulted in a revolution in knowledge of early metazoan evolution. The famous Burgess Shale of British Columbia, Canada, has prompted the recognition of other important biotas elsewhere, such as at Chenjiang and Kaili in South China. Despite the extensive record of Cambrian sedimentary rocks in the Indian subcontinent, no preservation of soft or weakly biomineralized parts has been recognized to date.
