In 1824, William Buckland stood in front of the Royal Geological Society and told them about the bones he had been studying – the bones of an enormous, lizard-like creature, that he called Megalosaurus. This was the first full account of a dinosaur. In this brilliantly entertaining, colourful biography – the first to be written for over a century – Buckland's fascinating life is explored in full. From his pioneering of geology and agricultural science to becoming Dean of Westminster, this is a captivating story of an exceptional and eccentric scientist whose legacy extends down to this day.
