I’m pretty sure they still have these things in Florida.
From this story on the BBC:
Around 58 million years ago, a monstrous snake slithered out of the swampy jungles of South America and began a reign of terror. Weighing more than a tonne and measuring 14m (approximately 50ft) the giant reptile could swallow a whole crocodile without showing a bulge. But a few years ago, scientists never even knew it existed._
“Never in your wildest dreams do you expect to find a 14m boa constrictor. The biggest snake today is half that size,” says Dr Carlos Jaramillo, a scientist with the Smithsonian Tropical Research Institute and part of the team that made the discovery.
_Thought to be a distant relative of the anaconda and boa constrictor, the snake – named Titanoboa – was not venomous. Instead, it crushed its prey with the constricting force of 400lbs per sq inch – the equivalent of lying under the weight of one and a half times the Brooklyn Bridge. The fossils were exposed by excavation at the massive Cerrejon open-face coal mine in northern Colombia. In 2002, scientists had discovered at that site the remains of a tropical rainforest from the Palaeocene Epoch – perhaps the planet’s first.
As well as fossilised leaves and plants, they unearthed reptiles so big they defied imagination. “What we found was a giant world of lost reptiles – turtles the size of a kitchen table and the biggest crocodiles in the history of fossil records,” says Jonathan Bloch, an expert in vertebrate evolution at the University of Florida. They also found the vertebrae of a colossal snake. “After the extinction of the dinosaurs, this animal, the Titanoboa, was the largest predator on the surface of the planet for at least 10 million years,” says Dr Bloch. “This was a major animal in any sense of the imagination.”_
Here’s an idea: we can clone Titanoboa, and then release them into the Everglades to control the pythons! What could go wrong?
