Sleeping on his side may be the least of this guy's problems.
Also: AI pictures are just so ugly. Do people actually click on these things?

Why would you name "rock dwellings" (actually 3D-printed concrete blocks) Navajoo and Hoodoo?
One a Native American Nation that do not build rock dwellings; the other a set of African American spiritual practices.
Why build "rock dwellings" in the flattest country on earth in the first place?

I do wonder which is more effective:
Our policy of appeasement? (which does not (or not fully) combat illegal detecting anyway (attached photo of recent example I came across)
Vs. a policy that would require perhaps more enforcement, but also makes the enforcint easier, like the Swiss one.

45k people calling on our politicians to pay attention to the biggest issue of our times: Climate change, which gets zero attention in the current Dutch elections.

Metal-detecting deteriorates into grave-robbing.
Visited exhibition on identification of victims from the Battle of Arnhem to encounter this case-study. Illegal metal-detectorist robbing a grave caught red-handed.
If not caught the grave would have disappeared unseen.

This is a Dutch one of my mom. But unsure if this would be likely to have made it to Polynesia.

We replicated backed segments of the South African Howiesons Poort phase (65.000 - 60.000 years old) and hafted them transversally and diagonally onto identical arrow shafts.
Shooting them at the same speed, at the same distance, at the same targets shows transversal arrows penetrate much deeper.

Very interesting stones in house in Dol-de-Bretagne. Never seen this before and no clue what it is/means. Anyone?

I am really enjoying SAFA conference @icarehb.bsky.social in Faro.
Here with Dr Reynard presenting work at Strathalan Cave.
Now looking forward to my own talk on the Middle to Later Stone Age transition at Umhlatuzana tomorrow morning.

Spoiler alert!
Neanderthal tar production made it to the New York Times puzzle app.
Impactful research is about reaching society. We can change how people understand the human condition, from puzzle to (hopefully) common knowledge.

I really enjoyed the Palaeoanthropology association conference andere the subsequent SAA conference in Denver.
Takeaway 1: I have kever before been so friendlily treated by US customs.
2: The US, or at least Denver have a serious mental health/homelessness/opium crisis

Current political realities (not naming names....) may really make 3 degrees warming the best-case scenario at the moment. So maybe we should move our collections higher still.... To Berlin? Or even to Mars?

With 2 degrees warming virtually inevitable. It seems we may have to more the Antiquities Museum to higher ground. Perhaps to the province of Drenthe?

How can Dutch archaeology cope with climate change? An important topic for a country with 33% of its area already below sea level.
Now there is a handy practical summary for archaeologists with clear actions and points of no return.

Why do diamonds and handaxes often occur together? Was Homo erectus after diamonds?
I trace how early diamond exploitation provided a wealth of information on the South African Earlier Stone Age. Exhibits like these were possible only because of diamond diggings.

You cannot consider the future without the past.
Inspirational quote by Jefferson at Leuphana university library is contested because of the past: why a slave holder's quote in the University library?
The future is shaped and constrained by history. I think we should pay it more attention.

Dutch Archaeological "living museum" Archeon now uses AI visuals.
In the Mesolithic we meet a bunch of corpulent half-naked Obelix-characters. White. No women.
We can debate Mesolithic people's skin colour (likely dark); they did not live life half-naked and there definitely were women.
