The Archaeology News Network and the DailySabah websites have info on the discovery. Here’s a snippet from the DailySabah website:

‘Archaeologists discovered a 3,000-year-old stamp believed to belong to the Assyrians during excavations carried out at the Zerzevan Castle in southeastern Turkey’s Diyarbakır province.

…

The stamp was found near the underground sanctuary located within the castle compound, which contains remnants of the city wall — which is 12-15 meters high and 1,200 meters long —including observation and defense towers, a church, an administration building, cereal and ammunition storehouses, an underground sanctuary, rock tombs, water canals and a cistern.

…[Aytaç ] Coşkun [the excavation director] said that the chlorite stamp, which has a clay imprint, is the only example of its kind due to the unique figures engraved on it.

“There is a deity figure on it. There is a tree of life in front of the deity and behind it is a bird. The deity figure on the stamp gives life to the tree of life with the cones and holy water in the bucket. There is a sacred meaning to the fact that the sun’s rays and the head of the god extend to the sky. Therefore, this seal is important,” Çoşkun explained.’
