Does a cave beneath Pembroke Castle hold key to fate of early Britons?

A cave beneath Pembroke Castle in Wales, known as Wogan Cavern, has revealed a treasure trove of prehistoric material including ancient bones and stone tools left by early Homo sapiens and possibly Neanderthals. Scientists hope this discovery will shed light on the settling of Britain in prehistoric times, including the end of Neanderthals' occupation around 40,000 years ago. The site, well-preserved with layers of bone, DNA, and proteins, presents a unique opportunity to understand how Neanderthals lived in Britain and how they were replaced by Homo sapiens. Unlike other prehistoric sites that were stripped of their materials, Wogan Cavern remains intact, offering a chance for modern technologies like sediment DNA analysis to provide insights into the interactions between Neanderthals and early humans. Researchers aim to use this technology to uncover details about population movements and the occupation of the cave over time, without the need for physical bones. The excavation at Wogan Cavern is expected to contribute significantly to our understanding of the prehistoric past in Britain.

For those near Wales, you can visit while the dig continues.

https://www.pembrokecastle.co.uk/events/view/archaeological-...

>From 17th June to 12th July there will be an archaeological excavation of Wogan Cavern taking place every day ... we are able to provide our castle visitors with some information on how things are progressing through our daily 'Cave Catchup' sessions. During these sessions a Castle Tour Guide will be in the Great Hall above the cave for approx one hour. So our visitors will be able to chat with the guide who will offer the latest information on the progress of the dig. There will also be the opportunity to see the dig site on a live video feed from the cave while the dig is in progress, and the chance to view replica artifacts of items identical to those that have been discovered at the site.

I grew up in this area a long time ago - not quite 40,000 years. This is my local Norman castle!

The obvious history you could see were the castles and walled towns. More recently, lots of ship building in the last 200 or so years, and plenty of WWII sites.

There are many other parts of Pembrokeshire with Stone Age sites that are well known, and there were clearly many people living in this area for a long time before even those later inhabitants

Very cool!

> Over the past few decades, scientists have struggled to explore this intriguing aspect of the settlement of Britain because they have faced a critical problem that affects many major prehistoric sites in the UK. In many cases, these have been stripped of all their sediment, rocks and other materials and so cannot be studied using the armoury of modern technologies that scientists have developed in the 20th century.

One hopes we will leave a few sites undisturbed so that 22nd+ century archaeologists can have a go with their fancy technologies.

Coastal or near-coastal sites are interesting because they are often very rich for forage food. But they're also complete buggers because of erosion. Coastal sites with hard rock and large caves/caverns which are capable of being continuously occupied for millenia are doubly interesting!

I'm curious (read "doubtful") about the claims for reliably detecting DNA and proteins in soils that are 100K+ years old.

For medical diagnostics, we even had trouble with small samples of blood directly and reliably obtained and stored.

For sandy soils, it's hard to imagine layers remain distinct given the porosity.

Wet soils would invite all sorts of other life.

The article lists no papers. The lead "Dr Robert Dinnis" is listed as an "honorary" (i.e., not active) research fellow at the University of Aberdeen.

It's fun to think about, though.

Pembroke Castle is a fantastic visit if you get the chance. The Welsh castles are dripping with "Game of Thrones" vibes. This one even has its own dragon cave.

Anyone else getting some Elden Ring vibes on this?
