Due to the Iraq War, however, looting has occurred more frequently. Entire archaeological sites have been destroyed, with as many as tens of thousands of holes dug by looters. The "Royal Cemetery At Ur", however, has remained largely preserved. The site was located in the boundaries of the Tallil Air Base, controlled by allied forces. It was damaged during the first Gulf War, when the air base was bombed. As a result, in 2008, a team of scholars, including Elizabeth Stone of Stony Brook University, found that the walls of the royal tombs were beginning to collapse. Deterioration was also recorded in the team's findings, due to the occupation of the military. Neglect, however, was cited as most harmful to the site. Stone stated that for 30 years the "Iraq Department of Antiquities" lacked the resources to properly inspect and conserve the site, along with others that the team examined. As a result, sites like the Royal Cemetery at Ur have begun to erode. In May 2009, "Iraq's State Board of Antiquities" regained control of the site, helping with the conservation of the ancient site. A vast number of individual graves, and a few royal graves have been identified at the Royal Cemetery of Ur. The attribution of the royal graves is generally tentative, but some efforts have been made to match them with royal figures otherwise known through inscriptions or regnal lists such as the Sumerian King List. Julian Reade has tentatively attributed the main tombs to the following rulers:  Tomb PG 1236, a twin tomb in the Royal Cemetery at Ur, is the largest and probably the earliest tomb structure at the cemetery, dated to circa 2600 BCE. It has been tentatively attributed to an early king of the First Dynasty of Ur named A-Imdugud ( ADIM.DUGUDMUŠEN, named after God Imdugud, also read "Aja-Anzu"), whose inscribed seal was found in the tomb. Several artefacts are known from tomb PG 1236. Two inscribed seals were found, one is a banquet scene with an inscription "Gan-Ekiga(k)", and another with the depiction of a nude hero fighting lions and a war scene reminiscent of the Standard of Ur, with the name "Aja-Anzu", also read "A-Imdugud". This seals is very similar to the seal of Mesannepada. Gold leaves with embossed designs, as well as a reconstituted gold scepter, have also been found in the tomb, as well as a royal scepter.
