Have you ever encountered a snake that was larger than an anaconda? Even the thought of such a massive serpent is terrifying when confronted with one.

A team of North American scientists lead by Jason Head of the University of Toronto discovered Titanoboa cerrejonesis, a brand-new species. It is one of the world’s largest open-pit mines and an unexpected windfall of ancient reptile fossils, and it is the most recent fossil to emerge from Colombia.

Titanoboa was also a large creature. Head estimated Titanoboa weighed over 1.3 tons using the length-weight ratios of a rock python and an anaconda as a guide.

That’s over thirty times the size of the anaconda, the world’s largest living creature. Titanoboa was not merely the biggest snake in the background, according to its outstanding measures. Following the extinction of the dinosaurs, it was also the largest land-living vertebrate.
