What do Tongtian Cave reports say about its 45,000-year date, and did labs confirm?

Research question: What do the primary excavation and dating reports for Tongtian Cave (Altai/Xinjiang) say about the roughly 45,000-year date, and have independent labs replicated it?

The Tongtian Cave excavation in Jimunai County, Xinjiang, lasted five years and the site was discovered in 2014 12. Its Sawuer Mountains chronology is given as punctuated occupation around 5200 to 3200 cal. yr BP, far younger than the roughly 45,000-year date in the question 3. The 45,000-year figures in the records instead belong to Tongtiandong, where a Mousterian layer was dated to about 46,000–44,000 BP calibrated and a 2017 report placed activity around 40 ka BP, and the records do not establish that Tongtiandong and Tongtian Cave are the same site 345. The records do not say whether any independent lab has replicated the date, and the 2016 early dating was only preliminary 7. The newest fact here is from 2023, about three years before October 2026 1.
