💁🏻♀️ TIL: 🦪⏳ Over two decades, scientists #carbon-dated over 7,500 #marine fossils from #ocean beds around the world.
The shared #data showed which environmental factor drives time averaging – the mixing of #fossils from different periods in a single sediment layer. The results show that #sedimentation rate matters most, setting limits on what fossil data can tell us about the past.

1/5 Is the Shroud of Turin a medieval forgery or a 2,000-year-old miracle? This 14-foot linen cloth bearing the faint image of a crucified man remains the most studied artifact in history. Science and faith clash in a quest for truth that spans centuries. Let’s dive into the enigma. #ShroudOfTurin #History #Science #Mystery #Archaeology #Relic #Religion #Jesus #Turin #Research #Physics #Faith #Art #Italy #Medieval #CarbonDating #Forensics #Miracle #Christianity #Discovery

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.

"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...

@jhaue from the article Charcoal deposited on the dune surface by past fires collects in sediment layers at the base of the dune. Patton et al 2023/Quaternary Research. “.. newly published research focuses on four well-dated sand dunes. Unlike previous studies that extracted fire histories from sediment cores from lakes, bogs and other organic sediments, we extracted fire records from these dunes. We believe this is a breakthrough that will greatly expand the areas for which we can extract fire histories….
For the first 1,000 years after the dunes stabilised, frequent but minor flows of sand grains down the front face of the dune slowly built up sediments at the foot of the dune. The sand deposited at the base includes the remnants of charcoal from local fires that deposited on the dune’s surface. This sediment builds up over time, preserving layers of charcoal from fires..”
