Did you know that the exquisite caves of Ellora were hewn from rock formed in the greatest lava floods the world has known?eruptions so enormous that they may well have obliterated dinosaurs? Or that Bengaluru owes its unique climate to a tectonic event that took place 88 million years ago? That the Ganga and Brahmaputra sequester nearly 20 per cent of global carbon, and their sediments over millions of years have etched submarine canyons in the Bay of Bengal that are larger than the Grand Canyon? Ever heard of Rajasaurus, an Indian dinosaur which was perhaps more ferocious than T rex? Many such amazing facts and discoveries?from 70-million-year-old crocodile eggs in Mumbai to the nesting ground of dinosaurs near Ahmedabad?are a part of Indica: A Deep Natural History of the Indian Subcontinent.
