If you were to list the creatures that scare you today, turtles probably wouldn’t be near the top of the list. Sure, a snapping turtle can destroy a finger or two, but generally speaking, turtles are pretty chill. If you happened to be hanging out in South America five to ten million years ago, however, you might have come across a turtle that wasn’t just scary, but downright massive.
The turtle, which is the subject of a new research paper published in Science Advances, was a true goliath. Weighing in at over 2,500 pounds, the beast now known by the scientific name Stupendemys geographicus would have been as large as a mid-sized car.
