In the Cerrejon Mine in Colombia, scientists found a host of giant fossilized leaves and super-sized reptiles that shed light on a prehistoric black hole, just after the death of the dinosaurs. These fossilized remains reveal that the earth endured a period of global warming leading to a whole new ecosystem - the birth of the rain forest - in which huge creatures battled it out to become the planet's top predators. Dominating this battle was Titanoboa, the biggest snake of all time.
