Agar 1954 on the deposits in the south west area of Cleveland.

Agar covered in detail the deposits to the north of Stainton created by the ice-dammed water-body that is said to have stood far below the 50 metre elevation of the Stainton site's.  Neither of the papers i have now looked at explicitly cover the south west area of Cleveland, but Agar ( 1954) maps the area as being till- covered with no detail on other beds in the area.
I can now with some confidence state that Agar mapped the area wrong, the area is far from a till covered glacial mess in fact i am yet to come across anything that resembles a till deposit or indeed any glacial erratics on the surface, every area i have excavated is proof in itself that Agar mapped the area wrong, and in doing so tells me he never actually looked hard enough to have the right to map it at all .

Magnetic rock found in the Stainton gravel beds.

This Basalt was excavated two days ago from the same excavation as the slab in the previous post. This i believe to be Basaltic Andesite from the nearby Cleveland Dyke, the Quartz or calcite veins i first thought were filled vesicles, but ime now sure there not.
The basalt is by far the most magnetic ive found so far, it attracts a magnet from 10mm away.

In my experience the tell tale signe to id Whinstone ( Basaltic Andesite ) can be seen to the top right of this image, its the white half circle that is the point of impact of the hammer blow that cracked the rock. Obviously the unique crystals also give a big clue!

New fossil rich slab dug from the Stainton gravel beds

This slab was excavated today it has the normal Gryphaea trace as a lot of the others but the bivalve? to the centre ime not sure of yet.

Large mammal c7 cervical vertabrae

These images show a c7 cervical vertebrae that probably belonged to a horse.

It was not excavated directly from the Stainton gravel beds, but could well have been washed from them.

  You can tell it is a cervical vertebrae because of the para vertebral foramen on each side of the centrum.  But it also has a facet for the head of the first rib.  The only cerv vert with a rib facet is the 7th.I receive a lot of welcome advice from very experienced Friends from the United States.

Rosedale ironstone and Stainton whinstone.

Ironstone from the Rosedale Magnetic MinesThis image shows the magnetic properties of the Rosedale iron stone, that was mined about 30 miles south east of the Stainton area, its stated that no other ironstone has been found with such  strong magnetic properties.
This is the only image i have been able to find of a rock with a magnet stuck to it other than rock from the Cleveland dyke ( basaltic andesite) and magnetite.
