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.
