摘要
Exceptionally well-preserved but isolated hexactinellid and monaxon sponge spicules are described from the Terminal Proterozoic Gangolihat Dolomite of Kumaun Lesser Himalaya, India. The small size of spicules indicates existence of small ancestral sponges during Neoproterozoic. Fossils of entire sponges are still not known from the Neoproterozoic.
