Some of the other studies:
Textile studies proving the cotton fibers came from the area
Textile studies showing the weave that was done matched other types of cloth from that time period.
Geologic studies which proved the shroud had picked up dirt from the limestone that is in Jerusalem's old city.
Pollen analysis identified 70 different types of pollen from the Jerusalem area, many of which were from flowers that occur during the sprintime.
The wounds from the scourging match a flagellum that is in a museum that was used at the time of Christ.
The blood type on the Shroud matches the blood type on the Sudarium of Oveido, the head covering which is considered by all to be authentic.
There is a wound on one knee that is swollen and matches the story of Jesus falling.
One shoulder shows that that the wounds from the flagellum were flattened, suggesting that was the shoulder he was carrying the cross.
There are two things on the Shroud that do not match the concepts depicted in art.
1. The "crown of thorns" was not woven into a crown but instead the wounds look like a clump from the bush was just stuck on his head. More plausible than soldiers weaving a crown.
2. The nails in the hands were not in the palms but in the wrist beneath the bone which is actually how the Romans did it.
The shroud cannot be taken off of any other person who was crucified for several reasons.
1. They did not scourge people who were going to be crucified.
2. They did not put crowns of thorns on people being crucified.
Finally, there is one unique thing about this burial shroud that you would never find in any other burial shroud.
They cut a strip off the shroud lengthwise about two inches wide and then they use that to tie up the shroud. This strip has been painstakingly and expertly sewn back onto the shroud. It would be impossible to do that to a shroud that had been in a tomb for any length of time, also why would you do that? This exhibits love and reverence for the shroud. It was done so well that it was not readily apparent to the investigators.
