Interesting. another place where Diatomite was mined is Loch Cuithir, which is relatively close to Skara Brae, and thats known for curious “stone balls”
Diatoms
Also
“Diatomite comprises fossilised remains of diatoms; single-celled aquatic algae. It is a sedimentary deposit consisting almost entirely of silica”
Is Jaime Maussan making a comeback? He’s tried for years to pass these off as ETs 
Aliens Cutaway | Nazca Humanoid Mummies: The Big Fraud. Episode-2 | Fake science spotlight
Like the title! Tales from out there! But the Mexican congress still gives him a platform!
X-ray scans of the two of Specimens presented to Mexican congress released by Canal del Congreso México.
The experts testifying under oath stated one has ‘eggs’ inside it and verified implants made of very rare metals of Cadmium and Osmium.
Osmium is one of the rarest elements in the Earth’s crust, making up only 50 parts per trillion, and the densest naturally occurring element.
This newly released specimen had a never observed abundance of Osmium.
A metal rod made of pure Osmium was found in the Cusco specimens. Osmium is the densest naturally occurring element. Pure osmium metal does not occur in nature. Osmium is used in satellites and space shuttles.
On the left an X-ray released by the Mexican congress on the Cusco specimens.
On the right is an ancient statue found in Cusco “Venus of the colds”. Made of solid of gold and…
…Osmium.
I have strong reservations about the alleged alien mummies from Peru presented by Jaime Maussan during the Mexico UFO hearings. Maussan has been duped in the past by fake cryptids that turned out to be composites of animal parts. I fear this spectacle will detract from the serious investigations underway in the US Congress.
a good match, living fossil 
Brilliant. I find this kind of “evidence” very odd as nearly all the time they look comical in some way. So what’s the point of it? At worst a distraction or at best some way to include something interesting burred in the jumble of plaster of paris cartoons? Its like here’s a tiny poorly made clown party with a scuba mask stuck to it, oh and this curious deposit or metal - that’s the only interesting part I think as it at least gives something useful although probably unrelated to check out. That scuba alien for me though, no. ill stick with events like the RFI or maybe long heads in long barrows etc for now
“Can a hoax be of such a massive scale”! YES it can, we’ve just lived through one.
And we all trust SciEntiSts…
Whatever anyone proves about these “corpses”, the ET meme will continue ad nauseam.
