Researchers extract ancient DNA from a 2,900-year-old clay brick
Researchers from the University of Oxford have extracted ancient DNA from a 2,900-year-old clay brick that originates from the ancient city of Kalhu.
Kalhu, also known as Nimrud, is an ancient Assyrian city located in Iraq’s Nineveh Governorate. The city covered an area of 890 acres and emerged as the capital of the Neo-Assyrian Empire during the reign of Ashurnasirpal II (883–859 BC).
Ashurnasirpal II constructed a large palace and numerous temples following a period of decline during the Bronze Age Collapse of the mid-11th to mid-10th centuries BC.
Numerous inscriptions found in the city have given researchers insights into the re-emergence of Kalhu, with one such inscription describing Ashurnasirpal II’s palace: “The palace of cedar, cypress, juniper, boxwood, mulberry, pistachio wood, and tamarisk, for my royal dwelling and for my lordly pleasure for all time, I founded therein. Beasts of the mountains and of the seas, of white limestone and alabaster I fashioned and set them up on its gates.”
During this period around 2,900-years-ago, a brickmaker prepared a clay brick for the palace construction, from which researchers from the University of Oxford have been able to extract and sequence ancient DNA by using a novel aDNA analysis.
The scientists managed to distinguish 34 separate taxonomic plant groups. Among these groups, Brassicaceae (cabbage) and Ericaceae (heather) stood out as the plant families with the highest number of sequences. Additional families that were represented included Betulaceae (birch), Lauraceae (laurels), Selineae (umbellifiers), and Triticeae (cultivated grasses).
The interdisciplinary group, consisting of assyriologists, archaeologists, biologists, and geneticists, managed to juxtapose their discoveries with contemporary botanical data from Iraq and historical Assyrian depictions of plants.
The mud composition of the brick was likely sourced from the nearby Tigris river, combined with substances such as chaff, straw, or animal dung. After moulding the brick into shape, it was then engraved with cuneiform writing and placed under the sun for drying. As a result of opting not to fire the brick and allowing it to dry naturally, this has contributed to the preservation of the genetic material trapped within the clay.
Dr Troels Arbøll from the University of Oxford, said: “‘Because of the inscription on the brick, we can allocate the clay to a relatively specific period of time in a particular region, which means the brick serves as a biodiversity time-capsule of information regarding a single site and its surroundings. In this case, it provides researchers with a unique access to the ancient Assyrians.”

Archaeologists from Cotswold Archaeology are excavating the crash site of a WWII B-17 Flying Fortress in an English woodland.
The B-17 Flying Fortress is an American four-engine heavy bomber aircraft developed in the 1930s for the United States Army Air Corps (USAAC).
The bomber was mainly used in the European theatre for daylight strategic bombing, complimenting the RAF Bomber Command’s night bombers in attacking German industrial, military and civilian targets.
Cotswold Archaeology have been tasked by the Defense POW / MIA Accounting Agency to search the crash site for the remains of the pilot, who died when the B-17 crashed following a system failure in 1944.

At the time, the plane was carrying a payload of 12,000lbs of Torpex, an explosive comprised of 42% RDX, 40% TNT, and 18% powdered aluminium. Torpex was mainly used for the Upkeep, Tallboy and Grand Slam bombs, as well as underwater munitions.
The pilot was declared MIA when the plane exploded into an inferno, however, using modern archaeological techniques, the researchers plan to systematically excavate and sieve the waterlogged crash site to recover plane ID numbers, personal effects, and any surviving human remains.
It is the hope of the excavation team members that they will be able to recover the pilot’s remains and return him to the United States for burial with full military honours.
The Defense POW/MIA Accounting Agency (DPAA) is an agency within the U.S. Department of Defense whose mission is to recover unaccounted Department of Defense personnel listed as prisoners of war (POW) or missing in action (MIA) from designated past conflicts.

Archaeologists excavating at the ancient Tharsa necropolis have uncovered a Roman Era tomb guarded by two carved bull heads.
Tharsa is located near Kuyulu village in southeastern Turkey along the Adıyaman-Şanlıurfa Highway.
The site was situated on a major Roman highway from Doliche to Samosata, which today consists of a two settlement mounds and a large necropolis that dates from the 3rd century to the Byzantine period.
Excavations first commenced in 2021 which discovered a collection of Turuş Rock Tombs, a type of tomb construction carved directly into the bedrock.
In the latest season, archaeologists have excavated another Turuş Rock Tomb, however, this example was found to have two carved bull heads which is decorated with garlands and rosettes between the horns.
Bull heads, known as Bucranium, were a form of carved decoration commonly used in Classical architecture. In Ancient Rome, bucrania were often used on the friezes of temples in the Doric order of architecture, later influencing the architecture of buildings from the Renaissance, Baroque, and Neoclassical periods.
Architectural examples of bucrania are representations of the practice of displaying garlanded, sacrificial oxen, whose heads were displayed on the temple walls.
Like similar Turuş Rock Tombs, the bull heads are carved directly into the bedrock, guarding a dozen rock cut steps descending into the burial chamber which has three arched niches known as acrosolia.
Mustafa Çelik, Deputy Director of Adıyaman Museum, said, “Tharsa Ancient City consists of 3 main archaeological areas: Big Mound, Small Mound and Necropolis Area. We started excavations in the necropolis area in 2024. We added 2 more rock tombs to the rock tombs we had previously uncovered. One of them is the rock tomb we identified today.”
