Take it or leave it. The question remains open. How old are the stones and who created them?

It's not an open question, it's pretty obvious they are frauds

Correctly sculpted by ancient peoples. The clay figurine (below right) is from the Pre-classical Chupicuaro Culture (800 B.C. to 200 A.D.) found near Acambaro, Guanajuato, Mexico. It seems obvious these people knew how Iguanodons appeared in life.

umm, no! It doesn't look like an Iguanodon at all. The hands & legs are wrong and it's too thin

Now look at these

Dinosaurs simply could not stand that way, their hips couldn't do it and their backs would have broke

Scientist knew this from the from the first time they found their fossils. Just when mounting them in museums, the museum curators found it easier to mount them upright, and because of this the "Godzilla" stance became ingrained into popular culture pretty much up to the 1st Jurassic Park movie.

So it's pretty clear, that these figurines were faked by someone who clearly got their ideas of dinosaurs from popular culture as opposed to actual people seeing real live dinosaurs in the flesh

They don't look like any artifacts that I've seen pictures of or seen in museums, either. They look rather modern and kind of cartoonish. Most clay figures I've seen are very I guess symbolic? The limbs are straight and blunt, details are cut into the clay and not contoured. These have little fingers, curly tails, and contoured teeth. I would be curious to see how they compare to other artifacts of this time period.
