Scientists Find Evidence of Ancient Gondwana Wildfires

• 27 May 2026

In May 2026, researchers from Birbal Sahni Institute of Palaeosciences (BSIP, Lucknow) discovered molecular evidence of massive wildfires in ancient Gondwana forests nearly 250 million years ago.

Key Points

• Research Area: Coal-bearing sediments from the Godavari Valley Coalfield linked to the Permian period.
• Scientific Techniques: Scientists used a novel multi-proxy approach integrating a technique called palynofacies analysis (study of tiny organic matter preserved in sedimentary rocks) with advanced molecular methods such as Raman spectroscopy and Fourier Transform Infrared (FTIR) spectroscopy to reconstruct Permian palaeofire events.
• Microcharcoal Detection: The study successfully differentiated high-intensity and low-intensity wildfire-derived microscopic charcoal particles.
• Combustion Evidence: Scientists identified Poly Aromatic Hydrocarbons (PAHs) and thermal alteration markers associated with ancient fires.
• Environmental Importance: The findings improve understanding of prehistoric climate, vegetation patterns, and coal-forming environments.
• Modern Relevance: Researchers stated that the findings may help improve climate models and understanding of ecosystem responses to extreme wildfire events.
