- Scientists from Birbal Sahni Institute of Palaeosciences (BSIP) found a 37,000-year-old bamboo fossil in the Chirang River, Manipur.
- The fossil belongs to the genus Chimonobambusa and shows thorn scars, nodes, and buds, features rarely preserved in bamboo fossils.
- This is the earliest evidence of thorny bamboo in Asia, showing herbivore-defence traits existed during the Ice Age.
- The discovery indicates Northeast India acted as a climate refugium while bamboo disappeared from regions like Europe.
