From the size of the 1.14-tonne Titanoboa, scientists have estimated the average annual temperature in the tropical jungle it inhabited 60 million years ago at 30-34 degrees Celsius (86-93 degrees Farenheit). "This shows how much more information about the history of Earth there is to glean from a resource like the reptile fossil record," said the assistant professor of ecology and evolutionary biology at the University of Toronto Mississauga. "The discovery of Titanoboa challenges our understanding of past climates and environments, as well as the biological limitations on the evolution of giant snakes," said Jason Head, member of the Panama-based research institute and lead author of the study to be published Thursday in Nature magazine. AFP - Scientists have found a 60-million-year-old fossil of the world's largest snake, a 13-meter (42-foot), one-tonne behemoth dubbed Titanoboa, in a coal mine in Colombia, the US Smithsonian Tropical Research Institute said Wednesday.
