The manuscript had been kept with a collection of other Middle Eastern books and documents, without being identified as one of the oldest fragments of the Koran in the world. When a PhD researcher, Alba Fedeli, looked more closely at these pages it was decided to carry out a radiocarbon dating test and the results were "startling". The tests, carried out by the Oxford University Radiocarbon Accelerator Unit, showed that the fragments, written on sheep or goat skin, were among the very oldest surviving texts of the Koran. These tests provide a range of dates, showing that, with a probability of more than 95%, the parchment was from between 568 and 645.
