How large was Gigantophis?
By comparing the vertebrae to those of living snakes, they were able to estimate that Gigantophis was around 7 metres in length. When discovered, researchers thought that Gigantophis was the biggest of all snakes ever known, and an analysis in 2004 estimated that it could grow to around 10 meters in length!

Why did snakes lose legs?
About 150 million years ago, snakes roamed about on well-developed legs. Now researchers say a trio of mutations in a genetic switch are why those legs eventually disappeared. Taken together, the mutations in the enhancer of a gene known as “Sonic hedgehog” disrupt a genetic circuit that drives limb growth in snakes.
