This has got to be the most amazing thing I’ve read this week, Evidence is mounting that large sandstone caves in Amazonian South America, large enough to comfortably walk through and the longest with 1,500 metres of tunnels, were carved out by giant ground sloths. Yes, ground sloths!
“The South American palaeoburrows might be the largest ichnofossils known so far.”

@OliverUv Hah! Yes, that would be a little person. I think instead it's a scale bar, so it's the black line that is 1 metre long.

@joncounts Fascinating! as we covered in our @bitsontape newsletter, sloth bones were apparently an important fashion statement for ancient people in the Americas. https://bitsontape.com/p/free-privacysafe-social

@joncounts I think they only look giant standing next to a human who’s shorter than 1 meter!

@joncounts did they do cave paintings as well? 😁

@rothko 😄 I'm not sure about paintings but ground sloths definitely did cave scratchings. If you hung a panel of that in a gallery, perhaps some would consider it art.
