Rib and distal tibia fragment excavated from Stainton gravel beds.

I found this rib piece over 2 metres into this dig, just above the packed gravels.

I also found what i think is a fragment of a distal tibia.

Note how packed the gravels are around the bone.

There are at least six different layers in this excavation, including the ever present red clay beneath the gravel layer. These two layers are to be found at all the locations i have excavated in the south west area of Cleveland, so i now think there is more than a good possibility that this sequence of layers extend from at least Stainton to Ormesby beck in the cypress road area of Marton Middlesbrough.

Example of the magnetic properties of the Cleveland dyke at Stainton.

I dug this cobble from Stainton Quarry and as with the majority of the whinstone ive tested in this area, it attracts a magnet. 

As far as i can gather at this preseant time the Andesite dyke stone from this area has never been reported as magnetic ie attract a magnet

The fact that this cobble attracts the magnet, and others I've tested in the old Stainton quarry workings, makes it clear that for some reason the dyke stone in the Stainton area has a different make up than that of other stretches of the dyke, one being the outcrop about a mile north west at Stainsby beck, the dyke stone in the outcrop did not hold the same magnet, yet a layer of broken down whinstone laying between two separate clay deposits above the dyke outcrop was all magnetic?
