Researchers report evidence of repeated burning of grass inside an Australian cave over an extremely long period, shedding light on ancient ritual practices associated with the GunaiKurnai people. Studies described in multiple outlets focus on plant remains preserved in sediments from Cloggs Cave, where grasses appear to have been brought in and burned rather than simply growing and burning naturally. According to the reports, microscopic analysis of preserved plant cells indicates that burnt plant material accumulates over tens of thousands of years, with timelines extending roughly 25,000 years. The findings are presented as archaeological support for ritual behavior in which controlled fires involving specific plant materials were used across many millennia. The research is careful to frame the interpretation as evidence of long-term practice, linking the cave’s use to the GunaiKurnai cultural context rather than everyday fire use. While the exact purpose of the “ritual” cannot be directly observed, the repeated pattern of grass burning is highlighted as an indicator that the activity was deliberate and sustained.
