I'm doing a dissertation project on the Wanstum Channel, a historic sea channel in East Kent dividing the Isle of Thanet and Kent. The channel was formed by rising sea levels at the end of the last glacial period however had silted up during the medieval age. My work focuses primarily on the physical geography and the lasting legacy of the channel. However whilst undertaking some borehole work roughly 100m from the River Stour (what remains of the Wantsum Channel) I have uncovered a small shell piece fragment around 2-3mm in diameter. If i could have this fragment identified it would mean I could use the fragment as a proxy for climatic and environmental conditions of the time, which will make a great talking point!
I'll be able to take further photos tomorrow with rulers to get exact measurements, but any help will be great. Cheers
