Titanoboa means titanic boa. It is a prehistoric snake which lived approximately 60 to 58 million years ago, following the extinction of the dinosaurs. This reptile – the world’s biggest ever snake – was between 12 to 15 metres (40 to 50 feet) long, about the length of a bus! It weighed as much as a small car – about 1135 kilograms (2500 lb). The thickest part of its body was about 1 metre (3 feet) thick.
The fossils of the Titanaboa was discovered in a layer of rock at a coal mine in Colombia, South America. It lived in the rainforest of north east Colombia. Titanaboa’s size tell us that the climate of the ancient rainforest must have been warmer than today – about 30C (85F). The warmer climate of the Earth during that time made it possible for cold blooded snakes to be bigger than the modern snakes. For example, the worlds longest and heaviest snakes today are the Reticulated Python, about 8.7 metres (28 feet) and the Anaconda at about 5.2 metres (17 ft). At this present time, cold-blooded animals in the warmer tropics tend to be larger than those found in cooler climate areas.
