Sorry, there's no evidence for that statement. They are all (probably) too new to be so.
Is this a pagan symbol?

Just because Sheelas are female and unexplainable against today's ideas of Christianity doesn't mean they are pagan.
By the way, I would love somebody to *prove* that they are pagan in origin, but all the people who have tried have failed.
