Could be in the future, someone will dig up remnants of our age.

It's not such a big leap. The "jagged rocks" are stone tools that are scarred consistently with breaking open bones for marrow...and the bones themselves are broken in ways consistent with being fresh as opposed to decayed. Or so the article says. Archaeologists are quite expert at this point with identifying stone tools. Doubt they made it up.

See the markings?

When he and his colleagues closely examined the rocks found near the mastodon fossils, they also found scratch marks. Similar marks appeared on the rocks used to smash elephant bones. Small chips at the site fit neatly into the rocks, suggesting that they had broken off while people used them as hammers.

Rolfe D. Mandel, a geoarchaeologist at the University of Kansas who was not involved in the study, found it hard to see how the rocks and bones could come together without the help of people. “It could not happen naturally,” he said.

But other archaeologists said the bone fractures and rock scratches were unconvincing.

“They present evidence that the broken stones and bones could have been broken by humans,” said Vance T. Holliday, an archaeologist at the University of Arizona. “But they don’t demonstrate that they could only be broken by humans.”

Gary Haynes, an archaeologist at the University of Nevada, Reno, said the researchers should have ruled out more alternatives. Some of the bone fractures could have been caused by pressure from overlying sediment, he suggested.

For years, Dr. Deméré and his colleagues struggled to figure out how long ago the mastodon died. The scientists finally contacted James B. Paces, a research geologist at the United States Geological Survey, who determined how much uranium in the bones had broken down into another element, thorium.

That test revealed, to their surprise, that the bones were 130,000 years old. Yet the fractures suggested the bones were still fresh when they were broken with the rocks.

Very cool find.

it's suggestive but not conclusive. there's no reason to break out the jump to conclusions mat. the article you linked had a video Nature put out with heavy skepticism about the whole thing as well

40,000 year old bracelet made by another species discovered in Siberia http://www.digitaljournal.com/science/4 ... cle/432798
Skeletal remains show that the Denisovans were probably far more robust and powerful than modern humans, and were, until now, assumed to be a more primitive, archaic type of humans than us.
But, the discovery of the bracelet suggests this was far from true. Amazingly, the skill involved in making this adornment shows a level of technique at least 30,000 years ahead of its time.

However, experiments have now definitely ruled that out, and they confirm that it could not have been made by homo sapiens or Neanderthals. After 7 years of analysis, the scientists are confident that the piece was made 30,000 years before the beginning of the Stone Age.

it was dated using this process: https://en.wikipedia.org/wiki/Oxygen_is ... atio_cycle (i'm not entirely sure how though, but that is totally obviously sentient-made. i can't even f**k say man-made, christ)


and if this isn't enough for the day to blow your goddamn mind

had the asteroid not hit gypsum rock, causing a monumental release of sulfur and blotting out the sun, and instead hit the earth mere minutes earlier or later, impacting instead ocean, the dinosaurs would probably not have died out. the scientists say it was the impact location rather than the size of the impact that destroyed so much life. but that also means mere minutes of a delay in an asteroid 65 million years ago and humanity would never have existed. i mean that asteroid could have been circling around for the entire life of the solar system, drawing ever closer, and it just hit the worst possible place for dinosaurs, best possible place for humans. the odds are... astronomical. i mean before i thought it was still very lucky, but that it hit arguably the only spot on the entire planet for the dinosaurs to all die? it's mind boggling.

That's why I laugh at those who complain about the events of the past. If things didn't happen as they did, their sorry asses probably wouldn't be around to complain about the past.
