…Many of the passages are longer than 600 yards (550 meters) and tall enough for an adult to walk through without bending.
The leading idea is that giant, extinct ground sloths dug these colossal shelters, turning parts of South America into a maze of underground homes…
…the tunnel walls are packed with claw marks, sometimes in three parallel grooves, right where a digging limb would bite into rock…


Clickbait title acting like it’s a mystery…
It’s obviously the giant sloths, because we can see the claw marks from giant sloths making them.
We’ve known for like a decade now.
Yeah… But we have no evidence that proves they were terrestrial sloths. They were obviously creating these complex tunnels deep underground to hide something. Something like a space craft or teleportation gate to the sloth dimension.
You’re just afraid to dig up the truth. #slothgate
Also they made the frogs gay
I recently read that these specific sloths evolved into transgender hermaphrodites which ultimately led to their extinction. They’ve actually traced their rise and fall to the implementation of space lazers causing massive flooding around the world. Funny how history repeats itself.
oh, you’re not even sarcastic

and here some people complain about moles
Mom! The giant sloths have dug up the neighborhood again!
Yeah, going off memory but they’re why avocados evolved too.
They were big enough to eat them whole and poop out the seeds, so they’re the reason we have guacamole.
Elephants are also known to dig caves in search of salt
