12 - I now believe that the stones found with the preserved bones must be connected i.e. were deposited by the same Humans that deposited the animal and Human remains. I still have not come across any metal items nor any signs that metal was deposited with the preserved bones and artefact's
This leads me to believe the grey deposits are of a considerable prehistoric age, also the fact that the Cleveland dyke could well have been exposed at this point, even possibly rising from the water makes me consider the dyke could have been the focus of a Prehistoric ritual centre here.
The image below was taken at an earlier stage of my work on these deposits, the partially excavated bone outlined in orange is a human tibia shaft, with a partially excavated mandible outlined in red, I found many more animal bones in this part of the deposit,
The links below show more of the excavated bone & artefacts from the lake bed deposits.
