Much more than 3,000 years ago.

It is part of the Puma Punku formation and is part of the site's oldest objects, but much older objects of similar manufacture can be found in other places
This site has many interesting artifacts. picrel was likely used to hold wooden dowels and pulleys for transmitting forces

This was made over 2,100 years ago. It's a hell of a lot more impressive than a smooth rock. Even cavemen understood the principle of grinding away softer rocks with harder ones.
Brayden Moore
Crazy how nature do that
Caleb Johnson
So what? I have to say it's not very impressive

Hello user. The objects at puma punku have a few different techniques employed in manufacture. Contrary to their appearance they are not carved blocks. These materials are not very well understood today but they are similar to a modern geopolymer, using a technique known as wet sand forming to achieve shape.
Geopolymers are produced at specific temperatures and pressures and deal with thermal expansion and moisture elimination when manufacturing. The specific materials contain rock clasts which are ground with molecular consistency and then allowed to polymerize using organic and inorganic amendments. The quality of this process is so high that semi-crystallization is achieved, so the makers were able to produce materials consistent in molecular properties from local sources as well as imported material from across the continent, and maintain this quality for 700+ of years.
Further, the large h shaped blocks at the site are arbitrarily ferromagnetic. The presence of metallic ions in the polymer slurry greatly increases complexity of manufacture with no obvious benefit. Geopolymers are serious technical feats requiring chemical knowledge, engineering and physics and a diverse industrial base

so? i could do this.

>To make their geopolymer sandstone concrete, the builders may have transported finely weathered, kaolinitized sandstone from the Kallamarka site and added foreign elements such as natron (Na2CO3) extracted from Laguna Cachi, a small lake (salar) located south of the great Salar de Uyuni, in the Altiplano (Bolivia).
>However, the most controversial aspect of the Pumapunku site is found in puzzling smaller items made of andesitic volcanic stone. Our study demonstrates that these architectural components were fashioned with a wet-sand geopolymer molding technique. The SEM study of this gray andesite shows the presence of organic matter (it could be the geopolymer binder). We have carbon, nitrogen, and mineral elements. The existence of amorphous organic matter is very unusual, if not impossible in a volcanic stone. It was also detected in the optical thin sections studies. It is a “unicum” and supports the idea of artificial andesite geopolymer concrete. To make geopolymer andesite concrete, the builders may have transported non-consolidated volcanic tuff, which is an andesite stony material having the consistence of sand from the Cerro Khapia site, and added an organo-mineral geopolymer binder manufactured with local ingredients.

What the fuck is this thread?

It's a cryptospam. Put herbs on it until the team gets extracte... I mean until the swelling goes down.

Nothing, go back to sleep.

Pumapunku is only about 1500 years old.
Ryder Martin
Incorrect. Some parts of the main site are dated from 1400-3000 years old. Others are 17,000.
Andrew Cook
That’s pretty cool I guess
Kevin Wright
the parts that are 17,000 old are flakes and chips.
William Wilson
Incorrect. The oldest layer of Pumapunku has been radiocarbon dated to 1500 years ago. There were speculations in the early 20th century that the site was as much as 15,000 years old, but we now know that is not true.
Gobekli Tepe is nearly 10,000 years older than Pumapunku.

Yes, most of the standing structures are dated to up to 3,000 years. Anything older than that has been moved and damaged so much accurate dating is difficult. Keep in mind archaeologists originally thought most of puma punku was over 7,000 years old because of the assumption that neolithic civilizations carved these blocks from stone using machinery. But now we know they used advanced geopolymers to make blocks that could withstand weathering like solid rock
Mason Wright
what happened to this race and civilization in the end?
