37,000-year-old bamboo found in Manipur may reveal Ice-Age secret
Scientists have discovered a 37,000-year-old fossil bamboo in Manipur's Imphal Valley, with ghostly marks of long-vanished thorns. "This is the first fossil evidence that thorniness in bamboo—a defence against herbivores—was already present in Asia during the Ice Age," they said. Bamboo fossils are extremely rare, as their hollow stems and fibrous tissues decay quickly, leaving little trace.
