A boomerang carved from mammoth tusk shows ‘Homo sapiens’ had symbolic thinking 42,000 years ago.
The new dating of the object found decades ago in Poland reinforces the idea that early humans in Central Europe had technological insight tens of thousands of years ago.

One rongorongo tablet carbon dated to mid-15th century, which means the script could have developed before European contact!

Well, this is fun. Scientists discovered an unexpected spike of beryllium-10 isotopes in Pacific Ocean sediments from 10 million years ago. This discovery could revolutionize geological dating methods, allowing scientists to better analyze Earth's history beyond the 50,000-year limit of carbon dating.
Hey, question- Are my ground.news links usable/of value for non subscribers? I hate paywalls. #science #carbondating
"The study provides an expanded chronological framework for human remains from the River Thames and supports future research into taphonomy, demography, skeletal trauma, and isotopic analyses of these human remains. Investigations into depositional scenarios may further clarify the role of watery places in later prehistoric ritual practices".

Chronology efforts led by researchers at Natural History Museum, London, and Historic England have produced 30 new dates for human remains pulled from the River Thames, establishing a chronological framework that spans nearly 6,000 years.
RETRACTED: Remember that eye-twitching, head-scratching paper published in a peer-reviewed journal, suggestively #carbondating the supposed #GunungPadang #pyramid between 25,000 & 14,000 BCE?
"Archaeological Prospection" finally retracted it. For good reason: https://onlinelibrary.wiley.com/doi/10.1002/arp.1932
Pseudoscience enthusiasts (myself included) will need to delete a few items from their conspiracy boards.
There's not much mystery regarding the age of the Giza Pyramids.
Someone in a Facebook group I'm in was looking for an explanation if #carbonDating that would make sense to a five-year-old.
It's tricky because we then have to assume none of the background knowledge most people pick up later! I might want to use pictures, really.
I thought I'd try anyway though...
There are two kinds of carbon. One of them (C-14) is radioactive, which means that it turns into something else over time: we say it 'decays'.
Half of that kind decays every 6000 years (actually 5730, but whatever). So after 6000 years, half of it will be left. After 12,000 years, a quarter. After 18,000 years, an eighth will be left.
So we can tell how old something is by how much C-14 it has! If it has one eighth the amount that living things have, it must be about 18,000 years since it died.
It only really works for things that were alive, because while they're alive they're always taking in new carbon by eating and so on. The amount of C-14 in the air is always about the same.
'But Fergus! Why is the amount in the air always the same? Doesn't that decay too?'
Yes! It stays the same because cosmic rays keep making new C-14, but that's a story for another day...
Why carbon dating extraterrestrial life forms makes no sense.
