Ammonite fossils collected from the bed of the Gandaki River at a place close to Saligrama or Muktinath (literally "place of salvation") in the Mustang district of Nepal are known as shaligrams or shilas and are considered aniconic representations of Vishnu. These are first mentioned in "Devi Bhagavath". In the puranas there is a description of a king, named Dharmadwaja, who was initially a devotee of goddess Lakshmi and who later became her rival which completely ruined him.
