In many places on the planet, there are stone artifacts that have strange defects. They cannot be attributed to chips, rock erosion. By all logic, these are defects in the manufacture of the artifacts themselves. But not mechanically, but when pouring (molding). Yes, again, consider the concrete technology or, in my manner, the version when this concrete was in plastic masses almost underfoot. In the so-called outcrops of cold fluidolites.
The Stone of Tizoc on display at the National Museum of Anthropology of Mexico.
At the bottom of this supposedly sacrificial stone, it can be seen that the ornament goes inside. But not worn away by erosion, namely the geometry of the stone, along with the ornament, "floated". A kind of dent.
Here this defect in the geometry of the stone is seen more clearly. The bas-relief depicts some kind of technical artifacts or weapons. But this is a separate topic.
A simple explanation of historians: this is what the masters did. The stone was initially uneven. But is it permissible for a ruler to do something with such a marriage? According to the same historians, such masters did not live long.

Polygonal masonry blocks were also sculpted from this geo-concrete. There are many traces of formwork.

They drew here, pressed a furrow in with a stick, and then stuck the stick into the rock several more times.
Many skeptics argue that these are natural rocks, not concrete. Yes, natural, but then they were still plastic, like these stones:
Cracks during deformation of plastic rock (and their surface is already petrified). Or it is superficial drying, which is also found on modern concrete. Another example: the formation of cracks when the clay dries.
The technology of casting or stamping is also proven by such artifacts from this region:
It can be explained as follows: a wax article with an ornament was poured with a plastic stone mass, and then drowned out.
Other examples:
Dent on a sarcophagus in the Cairo Museum. Did the craftsmen see a defect on the surface of the sarcophagus, anyway, did they apply hieroglyphs? Or was this dent formed afterwards? For example, did someone lean against a product that was not yet firmly inside, or did something fall on it?
Another dent on one of the faces of another sarcophagus in Egypt. The plane was not leveled, although, according to the logic, the craftsmen should have seen this defect when applying the inscription. Either the marriage was formed after the hieroglyphs were applied, the angle “floated”.
An exhibit from the museum. And also a dent in the stone along with the ornament. Not on purpose did the masters do this …
