Hello ! My name is Anna, I'm new here, I'm hoping someone can assist me with identifying what appears to be large bone ...or...rocks.
They are very white, porous, and YES I did stick my tongue to one, lol, it stuck.
I don't normally go around licking rocks, but these are pretty cool looking. i took pics yesterday.
Found on my friends 180 acre hunting ranch, near Concan, Texas.(west of San Antonio, hill country)
