Image released by Jason Head of Toronto Mississauga University, Canada, on 04 February 2009 shows a python creeping over a vertebra of a 'Titanoboa cerrejonensis', the largest prehistoric snake discovered in Colombia, South America. This snake lived about 40 million years ago in Egypt and is a relative of the Boa constrictor. The Titanoboa cerrejonensis was 13 metres long and weighed 1,140 kilograms, according with Nature magazine.
