At the beginning of the 21st century, South American scientists discovered mysterious and hidden tunnels underground. This was reported by Zamin.uz.
It was determined that these passages were neither the result of human activity nor natural geological processes, sparking great interest within the scientific community. In Brazil, geology professor Heinrich Frank noticed an unfamiliar hole near a construction site and decided to study it.
The tunnel was approximately four and a half meters long, with large claw marks on the inner walls and ceiling. According to Professor Frank, only powerful and giant animals could have dug such complex tunnels.
Research indicates that the creatures who dug these tunnels were giant sloths that lived 8,000 to 10,000 years ago. They moved slower compared to modern sloths but possessed strength comparable to African elephants.
More than 1,500 such underground passages have been identified in the Rio Grande do Sul region of Brazil, with the longest reaching 600 meters. These tunnels were likely dug by several generations of sloths.
A 2018 study conducted in Utah showed a close relationship between humans and sloths, confirming instances of hunting and persecution. These discoveries provide new opportunities for deeper study of natural and historical processes.
