*Also, I remember someone once said that spores were found on the shroud which were from plants that only existed in that part of Israel where Jesus lived and was crucified; I thought that was an interesting observation.*
Yes, and those spores were ONLY known to grow in Jerusalem, ONLY budding in the time of Passover/Easter!
Also, at least one of the found pollens come from plant that grew around Jerusalem until it became extinct around 700-800AD. There is no way a 12-13th century forger could have exposed the Shroud to pollen fromJerusalem from a plant that died out 400-500 years earlier. . . or, even know he would need to anticipate the science of palynology 700 years before it was created to include pollens on the cloth for palynologists to find.
