Bone found in latest excavation into ancient lake deposit at Thornaby on Tees Cleveland.

  1 As yet unknown Artiodactyle lower jaw and right Maxilla .
  2 I have only seen teeth like this once before , maybe just a juvenile thing ?
  3 The morphology looks bos to me .
  4 Although the teeth in the Maxilla look strange .
  5
  6 - 9  Unknown horn core .
  7
  8
  9
  10 - 12  Human tibia shaft .
 
  11 Its heavy and at least partially mineralised .
  12 Note the concretion attached to the left , ive found a lot of mineralised animal bones with a similar concretion . 
 
  13 - The mandible , maxilla , horn core , and Human tibia shaft were excavated from the same square foot of grey clay .

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 .
 
 
 
 
 8
 
 
 9
 
 
  10
 
 
 11
 
 
 
 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.  
 
 
 
 
 
 
 
 
 

Equus mandible excavated

  1 I excavated an Equus mandible at the weekend sadly the mandible bone disintegrated during the dig, leaving a full set of teeth including incisors, i also found the two equus metatarsals in the same area.
  2 The cervid metatarsal shown in images 2 and 3 and 4 was found not far away.

More fossil bone excavated from my main excavation.

 1
 The black line shows the bones still buried in the undisturbed deposit.
 2
The bones are shown within the yellow circle, with the gravel bed just below. 
 3
The bone location in this image is shown within the red circle, the gravel beds are outlined in yellow just below. 
  4 - The bone at first looked fragile, but after a wash and rub i found it to be heavy and hard, also it has the usual very high shine.
 
  5 The bone is part of the distal end of an as yet unknown scapula.
  6
  7
  8 - These two rib pieces were excavated close to the scapula piece, again they have the high shine.

 9 - This up to date view shows the gravel bed and the undisturbed deposits above.
 
 
 10 - This image shows the gravel bed outlined in yellow, and the red - brown plastic clay below outlined in red.
 
 
 11 - This image shows the gravel bed outlined in red, then two suspended gravel pockets outlined in yellow in the stoneless sandy deposit above, then the stoneless alluvium above the black outline.
