At multiple sites in the Middle Mountain we find granite stone with suture marks. It looks like the granite has been set in a mold just like a glass bottle is pressed today. The suture marks are inside the stone rather than outside. They usually form geometrical patterns like a rhombus or a straight line. They are clearly distinguishable by their regularity as not a natural occurrence.
In Rozovets we see several rhombus patterns in a slab of granite stone. The stone looks like it was set in a mold or pressed into like a stamp.
In Bania there is a straight line like a groove running the length of a megalith.
There are suture marks in the stone that remind us how glass is pressed into shape.
This technique can be associated with the early-Atlantean epoch of megalith building because it is usually applied to the smaller stones that are better finished. They stand on top of the larger ones from the Lemurian epoch.
