Megallithic sites in Uzbekistan (no replies)

Does anyone happen to know anything about megalithic sites in Uzbekistan?

I just watched this YT video. Lost Megalithic Civilization in Central Asia

These sites, as of the video making, are not yet registered as World Heritage sites.

This is what the screenwriter and director Bekruz Hammzaev says about this video project:

"This is one of the most imported project we have done so far. This document aims to challenge conventional thinking of history of Central Asia. The information about megalithic civilization is almost none to existant.
Potencially this film can rewrite the history of Uzbekistan we know.
I am honored to be able to make this project happen along with amazing people.
I can't thank enough our scientific team: Vladimir Karasev - Doctor of Historical Sciences. Discoverer of megalithic structuresas well as Konstantin Kraxmal - Doctor of Historical Sciences.
Discoverer of megalithic structures
Those amazing humanbeings devoted their life to ancient history and archeology and we just tried to tell their story.
Speacial Thanks to "Ziyo Forum" International Fund for Development of Science and Education for making it happen.
