The dig site, located along a sedimentary terrace in northern China, yielded elite burial goods belonging to an unidentified regional chieftain. Field researchers from provincial archaeological academies uncovered the artifacts placed flanking the skeletal remains: a serpentine jade carving curled along the eastern perimeter and an avian bone artifact settled directly to the west.
Stratigraphic analysis and accelerated mass spectrometry radiocarbon dates place the tomb layer firmly between 2350 BCE and 2200 BCE. This chronological window coincides with the critical transition from the late Neolithic Longshan period to the threshold of early Bronze Age urban centers. Prior to this discovery, the earliest confirmed pairing of dragon (Long) and phoenix (Fenghuang) motifs came from Shang Dynasty bronze castings and Warring States silk paintings, which dated no earlier than 1200 BCE.
The jade dragon measures 14.2 centimeters in length, featuring an elongated snout, circular orbital sockets, and dorsal ridges etched with quartz abrasive sand. In contrast, the phoenix figure, sculpted from deer antler bone and measuring 11.8 centimeters, exhibits a high crest, a curved beak, and geometric plumes sweeping backward along its torso. Their placement inside the tomb was deliberate: the dragon aligned with sunrise orientations, while the avian form pointed toward the setting sun.
