6-Foot-High Giant Tunnels Found in South America Dug by Ancient Megafauna Giant Sloths

By Rich Co Apr 11, 2023 07:20 PM EDT

Experts assert that ancient megafauna giant sloths were responsible for the 6-foot-tall giant tunnels that were discovered all over South America.

Giant Tunnels in South America
In South America, several enormous tunnels were found around the turn of the century, the year 2000. Following an investigation, the scientists who made the discovery concluded that neither a geological process nor any human activity produced them.

According to Discover Magazine, geology professor Heinrich Frank noticed a peculiar hole at a construction site as he drove by it on the highway. Frank went back to the tunnel that the excavation had revealed and wriggled inside.

It was a 15-foot tunnel. Frank was able to determine that the tunnel was not the result of geological forces. A much larger hint could be found at the end of the tunnel. The ceiling was covered in a smattering of enormous claw markings.

Giant “paleoburrows” dug by extinct mammals
June 24, 2017 • 3:15 pm

In the last few years, geologists have been finding—mostly in Brazil—large “paleoburrows” that were almost certainly dug by large, extinct mammals such as giant ground sloths. These burrows can be up to 3000 feet long (!) and 5 feet wide, though the very long ones were surely dug by many individuals over many generations. The shape of the burrows, and the fact that they bear distinct claw marks, are sure signs they were dug rather than being natural caves (the beasts could also have “improved” existing caves, but geologists think that’s unlikely).

Here’s what the excavations look like, from a summary of paleoburrows in Discover Magazine (captions from the site):
