Indiana Jones (“I hate snakes—I hate ‘em!”) would have totally despised a snake that lived some 60 million years ago. Because researchers working in Colombia have found the fossil remains of a snake that would have been up to 45 feet long, weighing in at perhaps 2,500 pounds. That makes it the biggest snake ever to have slithered across the Earth. The announcement appears in the February 5th issue of the journal Nature. The creature has been dubbed Titanoboa.

The fossil snake bones were found in an open-pit coal mine, along with its prey, which included turtles and crocodiles. Now, a snake this big could only live where the average temperature was between 30 and 34 degrees Celsius. So we gain info also about the climate at the time. Study leader Jason Head from the Smithsonian said, “The discovery of Titanoboa challenges our understanding of past climates and environments, as well as the biological limitations on the evolution of giant snakes. This shows how much more information about the history of Earth there is to glean from a resource like the reptile fossil record.”

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
