New large Cretaceous snake

A new species from the Madtsoia genus (which survived the KT extinction) has been found in India. Measuring about 5 meters long, M. pisdurensis was relatively big for today's snakey standards but much smaller than some other Madtsoia species (including Madtsoia bai from the Eocene, measuring over 10 meters long, and Madtsoia madagascariensis from late Cretaceous Madagascar which grew up to at least 8 meters long). The largest estimates for Madtsoia snakes have been up to 20 meters long!
It is very likely that more Madtsoia species will be found from the Late Cretaceous, probably in South America as well.

Madtsoia was part of the madtsoiid family of giant constricting snakes, which also includes Gigantophis (formerly known as the largest prehistoric snake) and Wonambi from Pleistocene Australia (making them an amazingly long-lived group, with members that dined on dinosaurs AND humans), but not Titanoboa which was a real boid. Titanosaur baby-eating Sanejeh, also from late Cretaceous India, was a madtsoiid as well.
