Tunnelling at Canary Wharf was too deep to disturb the archaeological deposits but samples taken by engineers before it began produced a fragment of amber and part of a woolly mammoth’s jaw bone.
This was another lucky discovery as it was spotted by a sharp eyed construction worker as the dock was drained. The fragment of bone is quite small but is thought to have come from a young mammoth.
The mammoth bone is also being analysed at the Natural History Museum. It comes from the jaw of a woolly mammoth which would have roamed the Thames valley some time between 100,000 and 12,000 years ago.
