Neanderthal Teeth from Pontnewydd Cave
By Elizabeth A. Walker
National Museums & Galleries of Wales excavations at Pontnewydd Cave, Denbighshire have discovered the oldest human remains known from Wales dating back some 230,000 years.
The 19 teeth were mainly found deep inside the cave where they were washed by melt water from an ice cap that covered much of Wales. They have been identified by experts at the Natural History Museum, London as belonging to an early form of Neanderthal.
Neanderthals are one branch of the human evolutionary tree that is thought to have died out approximately 36,000 years ago. Our own species shared a common ancestor with Neanderthals, but did not evolve from them.
Neanderthals were fairly short and stocky, had ridges under their eyebrows, big square jaws, and teeth that are larger than ours are today.
Study of the teeth found at Pontnewydd found that these represent the remains of five individuals.
The teeth have all been x-rayed and they show an interesting characteristic known as taurodontism - an enlarged pulp cavity to the teeth and shorter roots. Taurodontism is a characteristic (although not unique) feature of Neanderthal teeth and it is the prevalence of this that has led experts to decide that these are Neanderthal as opposed to another early human.
The people discovered in Pontnewydd Cave range in age from young children to adults. The most complete discovery from the site is a fragment of an upper jaw of a child aged around eight years old. In the jaw a very heavily worn milk tooth can be seen sitting next to a newly erupted permanent molar. Had this child lived, this new tooth would eventually have pushed out the milk tooth.
The teeth were not found on their own inside the cave. Associated with them were stone tools and animal bones, some of which show signs of butchery - evidence that these were the food remains of these early Neanderthals.
Questions remain as to whether these humans were originally buried in graves within the cave. Unfortunately the forces that have remarkably led to the preservation of these teeth deep within Pontnewydd Cave destroyed any traces of their original burial context.

Pontnewydd Cave was excavated by the National Museums & Galleries of Wales between 1978 and 1995.
The wall that can be seen across the entrance to the cave was built during the Second World War, at which time Pontnewydd Cave served as a munitions store.
