Nice to know porn has been with us since the dawn of time. And will be with us until the sun super-novas. There is some controversy as to whether the carving does indeed represent a vulva since the scientists who made the discovery have never actually seen one (full disclosure - stolen joke from comments in referenced link). Me - I'm going with a dandelion. Unless the guy carved it one handed. Then maybe I can see it.
