The curious case of paleoburrows

[Thialfi]

Interesting read!

"It wasn't until 2015 that Amilcar Adamy of the CPRM had an opportunity to return to that strange cave in Rondonia. It turned out to be the first paleoburrow discovered in the Amazon, which is notable, but not the coolest part. It also turned out to be one of the largest ever measured, with branching tunnels altogether tallying about 2,000 feet in length. The main shafts — since enlarged by erosion — were originally more than six feet tall and three to five feet wide; an estimated 4,000 metric tons of dirt and rock were dug out of the hillside to create the burrow.

"This wasn't made by one or two individuals," says Adamy. "It was made by many, over generations." Frank describes it as an exciting, though not particularly surprising, discovery."

Cool, thanks for sharing!

Interesting indeed!
...and funny when it is written exactly what you are thinking: "I didn't know there was such a thing as paleoburrows"

Very interesting, thanks!

Yes very interesting - there's a good b movie in there somewhere, waiting to get out. Looks like the set of "Them!"

I've never heard of these before.  Interesting stuff....the movie idea is a good one;  an ancient paleoburrow is uncovered and the original owner revives from its 10,000 year slumber...
