Gravel bed sat directly on top of Mercia mudstone.

  1 - This exposure at stainsby beck shows a gravel bed sat directly on top of Mercia mudstone.
 
 
  2 - The gravel bed can be seen quite clearly sat on the red Mercia mudstone, above the gravel bed the deposits are the same as ive found above the Stainton gravel beds excavated so far in the south west area of Cleveland.

 
  3 - The Mercia mudstone outcrops in the western Bank of Stainsby beck are red and green - blue ime told this is due to a fault.

Megaloceros mandible

 1 -  I have  been reliably informed that this  is a  Megaloceros mandible.
 
 
 2 - The m3 molar matches a lot of the large fossil cervidae m3 molars ive viewed.
 
 
 
 3 - The muscle attachments are very pronounced i have no mandible that matches these attachments.
 
 
 4 - It is the only mandible ive seen with these muscle attachments on the underside of the jaw.
 
 
 5 - The muscle attachment pattern on the inner cheek again is like none i posses or have viewed.
 
 
 
 6 - In this image although not exact the difference in the angle of a line drawn through the nerve
 cavity the bos examples are far more severe.
 
 
 
  7 - With bos mandibles either side its not hard to see a big difference .

 12 - Note the depth of the cavity for the muscle attachments.
 
 
 13 - 14  Again note the angle difference with the bos example.
 
 
 15 - I don't believe this is the mandible of a Megaloceros gigantius but it is from a huge Cervid of Equal size.
