What valuable raw materials would those be? I'm assuming you can deduce this from just the photos as well.

> What valuable raw materials would those be? I'm assuming you can deduce this from just the photos as well. I can think in several reasonable possibilities to check for. I'm assuming that you are able also. I will not enter in that "If you are so gooood, show me that you know all" game. Lets focus in the facts of the problem, not in me, or in my "arrogance".

  Maybe I misunderstood, your premise is that these were dug by humans looking for valuable materials but you are not willing to engage in the "here's evidence to support my claim" game? That's not a good way to ever be taken seriously but I guess you can tell that already.

  > What raw materials whould those be? My first guess where pure clay and maybe salt. After reading the article and seeing the "comb pattern" linked with a source of water, and the "seats" and the "reinforcement arcs" and the forked tunnels I would add also to this list some precious or semiprecious stones of aluvial origin filtered from the mud (would explain also the rounded section of some but not all parts of the mine). There is not need of an iron pick to dig in clay. It helps, but all you need is a wood stick with a fire-hardened point.

    More reasons for a nonhanthopogenic explanation: Some of the smaller burrows (dug by armadillos) are too small to fit a human. These kind of burrows are only found in south america. There is no evidence of human presence (wall paintings, fireplace remains, etc). Except in some cases and even then only at the very entrance (suggesting that people found these later but never ventured in the dark parts) There is evidence of claw marks on the walls, but no evidence of human tool use (pick axes, etc) Some of the burrows are dug in sandstone.

Keratin is softer than sandstone and a soft material will not scratch a harder material. This is evidence against non-anthropogenic theory unless you add teeth to the equation (but sloths and armadillos belong to the order edentata, that means "toothless"). They do not have strong renewable frontal teeth like rodents have
