Yes. The quarried limestone has evidence of skeletal remains, most probably of marine origin, indicating that this bed of limestone was formed under the sea and uplifted to its present position.
However, the wall block limestone exhibits no such qualities and, is in fact, a different limestone altogether as proven by the Russian scientists. As already stated, it contains no material which is most often found in sedimentary limestone but is microcrystalline in nature.
Now, leaving magic and reconstitution by some long, lost ancient technology aside, how could this situation have arisen?
Below is an image of the Water Temple at Sacsayhuaman. The blocks at this site are not megalithic but are in the same configuration as those of the Walls. Like little children who haven't grown up yet.
BTW. Best to leave Davidovits for another thread. Different template.
