Hello Everyone,
Could you please help us with what these are? 
pic 001 we are not sure
pic 002 we think is petrified wood, we found at the bottom of Overholser Dam in OK
pic 003 another pic of 002
pic 004 Aaron wants to know what this is or what this would have been maybe if he did not crack it open. The center is red and chalky but seems to get harder as we scrape it but I told him to stop.
pic 005 This is dense, and it writes, Aaron thinks lead?
 
Thanks for the help.
Shawn and Aaron
