Popping Stone 1

thats the most important word.... "man"..it must have connection with man to classify it as prehistoric, shaped, erected or used by, all of those would qualify it as a standing stone.

Yeh, I remembered after posting an archaeologist saying that a s.s. had to be taller than a straining post. Which considering how many absolutely standing stones have been used for such would make a lot of folk unhappy ;-)
