The World's Largest Snake: n 2009, a group of passionate scientists stumbled upon fossils of the titanoboa - the biggest snake of all time. At 48 feet long and weighing well over a tonne, the snake is one of the greatest discoveries since the T-rex. The animal is a relative of modern boa constrictors and lived in the rainforest of north-east Colombia 58-60 million years ago. The spectacular palaeontological find deep in the Cerrejon coal mines in Colombia has blown the doors off a lost period in prehistory.
