(Bharat / Sanatan in ICE AGE) : 37,000-Year-Old Thorny Bamboo Fossil Unearthed in Manipur Sheds New Light on Asia’s Ice-Age Flora
A remarkably well-preserved bamboo stem discovered in the silt-laden deposits of the Chirang River in Manipur’s Imphal Valley has opened an unexpected window into Asia’s ancient plant life. Researchers from the Birbal Sahni Institute of Palaeosciences (BSIP), an autonomous institute under the Department of Science and Technology (DST), identified clear thorn scars on the fossil—marking it as the oldest known thorny bamboo fossil from Asia.Bamboo fossils are exceedingly rare due to the plant’s hollow, fibrous structure, which typically decomposes before fossilisation can occur. Until now, scientists largely relied on modern bamboo species to infer how ancestral plants might have defended themselves.
Detailed laboratory analysis of the fossil’s nodes, buds, and distinctive thorn scars enabled researchers to assign it to the genus Chimonobambusa. Comparisons with living thorny bamboos such as Bambusa bambos and Chimonobambusa callosa helped reconstruct its defensive adaptations and the ecological conditions it once faced.
This 37,000-year-old specimen offers critical insights into the region’s Ice-Age vegetation and may reshape current understanding of bamboo evolution across Asia.
