Bone excavated from deposit above Stainton gravel beds.

I found these rib pieces today in my main excavation at Stainton beck, the end of one of the ribs can be seen just below the end of the tool. Other parts of the two ribs fell away as i removed the clay, they can be seen in the top right of the image.

The image below shows the packed sandy clay layer just above the Stainton gravel bed, before i started digging.

Note how tightly packed and previously undisturbed the clay around the bones are.

The image above shows one rib above the other in the centre.

This image shows the sandy clay layer that contained the bones now removed, the layers above and there are at least two were created by the last actions, of the retreating ice of the last major cold stage.
