Abstract
최근 캄브리아기 초기에 해당하는 동물군 화석이 중국 운남성 부근에서 다량 발견되었다. 이 동물군 화석은 5억 2천만 년 전에서 5억 2천 5백만 년 전의 연대를 가진 마오탕샨 셰일에서 산출되며, 캐나다 로키의 버제스셰일동물군과 그린란드의 시리우스파세트동물군보다 약 1천만년 내지 2천만년 더 오래된 동물군으로 판단된다. 청지앙동물군은 아주 다양한 동물 화석으로 구성되며, 몸체의 약한 부분이 잘 보존되어 있다. 이러한 조건은 유수, 생란 작용, 생화학 작용을 받지 않는 환경 즉 반복된 빠른 퇴적작용에 의해서 화석화된 것이다. Recently lots of the Early Cambrian fauna were described from the Yunnan Province of China. The fauna occurs from the Maotiangshan shale that dated between 525 and 520 ma, which is about 10-20 million years earlier than the Burgess Shale fauna of Canadian Rocky Mountain and Sirius Passet fauna in North Greenland. The Chengjiang fauna comprises an extremely diverse faunal assembly, and soft body parts of the fauna are well preserved. Such condition probably resulted from repeated rapid burial environment that prevented the bodies from destruction by currents, bioturbation, and biolchemical activities.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
