Actually still I didn't know that what is it,how is it? But few days ago me and one of my friend go for the travel to kathgodaam river.we were sat at the river bank.. At first my friend saw it and ask me to check out it. We were thinking that it is some type of or pendant but frist I stopped him and captured some pictures of it after I asked him for pick it up but when he touch his hand on it.. It was just sand and mud..
