Researchers in India have found fossils of an ancient giant snake that could have been longer than a school bus.

A ancient giant snake in India might have been longer than a school bus and weighed a ton, researchers reported Thursday.

Fossils found near a coal mine revealed a snake that stretched an estimated 36 feet (11 meters) to 50 feet (15 meters). It’s comparable to the largest known snake at about 42 feet (13 meters) that once lived in what is now Colombia.

The largest living snake today is Asia’s reticulated python at 33 feet (10 meters).

The newly discovered behemoth lived 47 million years ago in western India’s swampy evergreen forests. It could have weighed up to 2,200 pounds (1,000 kilograms), researchers said in the journal Scientific Reports.
