The discovery of fossilised remains belonging to the world's largest snake has been reported in Nature journal.
Titanoboa was 13m (42ft) long - about the size of a London bus - and lived in the rainforest of north-east Colombia 58-60 million years ago.
The snake was so wide it would have reached up to a person's hips, say researchers, and was estimated to have weighed more than a tonne.
Researchers discovered fossilised bones belonging to the super-sized slitherers and their possible prey at Cerrejon, one of the world's largest open-pit coal mines. The animal is a relative of modern boa constrictors.
I suspect this may be the equally large boa of myth and mayhem.
Or is this it?
