Paleontologists in India just identified a gargantuan prehistoric snake that roamed the Earth 47 million years ago. The largest living snake on Earth today is the reticulated python, with the longest specimen ever found measuring in at nearly 33 feet — but Vasuki indicus grew anywhere from 36 to 50 feet in length. The massive creature had at least 800 vertebrae and likely killed its prey through constriction. Although scientists aren't sure what exactly Vasuki feasted on, they found creatures like ray fish, turtles, crocodilians, and primitive whales within the same fossil layer that may have served as its food source.
