Oldest fragment of Romans?

John Byron over at The Biblical World has drawn our attention to a CNN clip with Steve Green of Hobby Lobby presenting some of the manuscripts of his collection including a fragment of Romans that Scott Carroll dates to the mid-second century.  That would be about 50 years earlier than the Chester Beatty papyrus p46 (ca. AD200) and would thus be the oldest fragment of Romans to date (about the size of the oldest NT manuscript of all, p52 of John, which dates to about AD125).

IWU's Jerry Pattengale is heavily involved in the administration of the Green Collection as well, and Green is the principal donor for Wesley Seminary's upcoming new building.
