Abstract
Some fossil seeds of Celtis L.accompanied with the occurrence of Donghulin 4,whose ~14C age is about 8540 BP(c.7500 BC) from the village of Donghulin,Zhaitang,Mentougou district of Beijing,are demonstrated separately as C.bungeana Bl.and C.cf.koraiensis Nakai.Based on the known data,seeds of Celtis L.contain rich nutrition and minerals.And there was a long history for our ancestors to eat the fruits and seeds in north China,through Peking Man site,Donghulin Man site to Bancun site(Peiligang culture).Possibly,the grinding of Celtis seeds is one of the functions of the ground stone collected in Donghulin Man site.Through a comparison on the development of endocarp in the living Celtis species with those of fossil seeds,it shows that the endocarps of fossil seeds are mature(at the late autumn,i.e.,probably in October).Therefore,it indicates that the accompanied Donghulin 4 died at the same time.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
