"The analysis is intriguing, but several experts cautioned that more research is needed to confirm that time line. The Holocene age estimate is only inferred and not measured, so the age is very uncertain, says Mark Boslough, a research professor at the University of New Mexico, who was not involved in the study.

"Other experts are more sanguine: Geologist Steven Jaret says the team only suggested that the impact most likely occurred during the early to middle Holocenean estimate supported by the data in the study. Jaret, who was also not involved in the study, emphasizes that the researchers agreed that more work would be needed to precisely date the crater. Scientific American has reached out to the authors for comment."
Scientists identified a bowl-shaped impact crater in China measuring about 900 meters across and named Jinlin crater. Geological analysis indicates the structure likely resulted from a meteorite impact during the early to mid-Holocene epoch. The Holocene age estimate is inferred rather than directly measured, leaving the crater's age uncertain. Some experts caution that additional fieldwork and precise dating techniques are required to confirm the time frame. Other geologists find the early-to-middle Holocene interpretation plausible based on available data but agree that further work is necessary to precisely date the crater.
