A fossil of the "largest snake to ever have existed" has been found in western India. Twenty-seven vertebrae belonging to a 15-metre-long non-venomous creature scientists have named Vasuki indicus - longer than a T Rex - were discovered in Panandhro, Gujarat. Debajit Datta, postdoctoral researcher in palaeontology at the Indian Institute of Technology Roorkee, said: " Vasuki was a slow-moving ambush predator that would subdue its prey through constriction like anacondas and pythons. "This snake lived in a marshy swamp near the coast at a time when global temperatures were higher than today."
