Ancient use of stone from the Cleveland dyke at Stainsby beck

I made an earlier post showing the Cleveland dyke at Stainsby beck in the south west Cleveland area, i now after further visits and research believe the stone was taken from this outcrop and used at least in the nearby area.
Ive found large amounts of the stone that seem to have been used as dams of some sort in at least four different locations, all upstream from the dyke exposure, I've found no historical reference to the dyke being utilized at this exposure point at Stainsby, so can only imagine it was a very long time ago.

I will be researching this area a lot more in the future as i believe it has a hidden and yet unknown history.

Comparisons

Hello all if anyone with an interest in my finds, or the geology i am finding them in has any information that they think may help, please post comment and i would be most happy to post any comparative images.
I hope that once properly identified the fossil bone on this site can be used as accurate reference for anybody needing it for there own research, as i know how hard it can be to get trusted comparisons and information.
