The Shengjizui tomb cluster

The Shengjizui cemetery (生基嘴墓群) lies in Bishan, Chongqing. Ten individuals from the cemetery yielded usable ancient DNA; six carry Y‑chromosome lineages downstream of D‑M174, and all six sit within the continental D‑F6251 branch. The source study reads the cemetery against the Ming‑dynasty resettlement of Sichuan and Chongqing.

The tombs are stone‑slab chamber graves, cut in dense parallel rows into the hillside.

Transcribed from the source publication. Y‑haplogroups are given in the paper’s combined ISOGG-plus-SNP form; the shorthand used on this site is shown in the last column. An asterisk with x… means the sample tested negative for the bracketed downstream markers.

Note: M10-1 is published as D1a1a1a1a, whereas the other five are D1a1a1a1b — one letter apart, a genuine split within the cemetery rather than a typo on this site.

Aerial view of the Shengjizui cemetery under excavation
The cemetery from above. Stone-slab chamber graves are laid out in dense parallel rows across a cleared hillside terrace, bounded by subtropical woodland and terraced fields.
A single long row of about ten stone chambers
One row of roughly ten adjoining chambers, capstones still in place, sharing common dividing slabs — a construction sequence consistent with a single kin group extending the row over time.
Five adjoining chambers with capstones partly removed
Five adjoining chambers cut into the slope, capstones partly lifted, showing the slab floor and dressed side walls.
Several rows of chambers mid-excavation, some covered with blue sheeting
Several rows mid-excavation; blue sheeting protects burials already opened. The stepped arrangement follows the natural contour of the slope.
Close view of chamber construction with dressed stone slabs
Chamber construction in detail: dressed slabs form floor, walls and lintel, with a shaped stone doorway at the front of each cell.
Opened chamber with skeletal remains and grave pottery
An opened chamber with skeletal remains still in position and ceramic vessels set at the head end; the adjacent cell holds a second burial.
A burial in situ, supine and extended, with vessels at the head
A burial in situ — supine and extended on the slab floor, with two vessels placed beyond the head. The pelvis and long bones survive well; the upper body is more disturbed.
Close view of a skull with timber coffin remains and a green-stained object
Cranium beside decayed coffin timbers. The turquoise staining on the slab and around the bone indicates corroded copper-alloy grave goods.
