Ancient Sulawesi Rock Art Dates Back 67,800 Years
The discovery of ancient rock art in Sulawesi, Indonesia, has drawn significant attention due to its historical implications. Recent studies indicate that this rock art dates back approximately 67,800 years, making it one of the oldest known examples of artistic expression.
Ancient Sulawesi Rock Art
Researchers conducted extensive analyses at the BIOMICS laboratory within Southern Cross University, located in Lismore, New South Wales, Australia. Utilizing advanced technologies, the team employed uranium-series dating methods to ascertain the accurate age of the paintings.
Methodology
- Laser Ablation: An ESI NW193 ArF excimer laser ablation unit was used alongside a MC-ICPMS Thermo Fisher Neptune XT.
- Isotopic Mapping: Geochemical imaging involved mapping calcite formations to determine isotopic ratios.
- Sample Measurement: Measurements were taken using a spot size of 44μm, with adjustments to account for sample irregularities.
This sophisticated approach allowed scientists to reconstruct an isotopic map that detailed uranium and thorium concentrations in the rock art samples. The study also relied on NIST standards for accurate calibration and drift correction throughout the analysis.
Findings
The uranium-series data produced revealed significant insights into the age of the artwork. The ages calculated provided a strong chronological framework, confirming that the rock art is indeed among the earliest known forms of human creativity.
Implications of the Discovery
This groundbreaking discovery of the ancient Sulawesi rock art raises essential questions about the origins of artistic expression among early humans. The evidence suggests complex cognitive abilities and cultural practices existing far earlier than previously believed.
Such findings underscore the importance of the region in understanding early human behaviors and the development of art. As more research surfaces, the ancient tradition of rock art in Sulawesi will play a crucial role in deciphering the cultural history of human civilization.
