2,000 Mysterious And Massive Prehistoric Tunnels Found In Brazil
Within the last decade, the hunt’s really been on by paleontologists and geologists to locate as many as possible of the huge, neatly-constructed tunnels located deep in the jungles of South America. About 2,000 of these truly wondrous tunnels have been found, with the majority of them discovered by scientist Heinrich Frank.
Working From Scratch
The most obvious scientific clue that the impressively made tunnels weren’t natural geological formations, but instead were «paleotocas or paleoburrows» dug by prehistoric animals, was the claw marks on all of the tunnel walls. The next step was to pinpoint which animal it was, since all of the scratches in the dirt were made by the same type of creature.
Identifying the animal who made those thousands of incredibly large South American tunnels was a tough job for paleontologists, but identify they did. The extinct megafauna giant sloth, Lestodon, is credited as being the tunnels’ creator.
