1 I could be wrong but I believe this flint that was excavated from the same grey deposit as the bones and leather reported in earlier posts , was very likely used as a fire starting implement .

3 This image shows a similar piece note the angles and percussion marks .
1 - The grey deposit can be seen behind the ruler.
2 - This image shows a proximal tibia shaft before excavation.
3 - The Canis ulna on the left was excavated deep into the deposit, the larger Canis ulna was found at another location.
4 - The larger ulna looks large enough to possibly be wolf .

6 - I also excavated this piece of black flint from deep into the deposit, i don't know a lot about worked flint but this piece could have been.
7 - I am sure Tees archaeology will know one way or the other and will post there opinion .

1 - This piece was excavated from the top left of this deposit .
2 - It appears to have several different mineralised layers including what looks to be preserved organic material maybe wood ?
3 - The outer concretion appears to contain a lot of quartz grains .
4
5 The preserved organic material can clearly be see in this image, at first i thought it to be preserved wood , ime now not so sure and believe it could be preserved none mineralised bone .

7 - The white mineral i am still unsure of but it is not calcareous .
1 - The leather shoe sole shown in earlier posts found close to deposits ive worked near Stainsby beck Thornaby on Tees Cleveland .
2 I have now cleared most of the holes that look to have been created by a bone tool .
3
4 - Note the leather has been doubled up .
4 The leather was found close to the same Prehistoric deposit as the pottery below .
5 These pottery pieces excavated very close to the preserved shoe sole, Peter Row of Tees archaeology informed me he believes to be iron age.
1 This image shows the entire collection of excavated fossil bone including at least seven different animals including horse, ovis -capra, bos, cervidae, and Human tibia, and a leather artefact i believe to be the sole of a shoe, that looks like it has been decorated with worked fossil bone. ( See update )
2 This leather artefact was excavated about 300 mm into the previously undisturbed grey clay deposit.
3 I hope this image shows what i see ime sure worked bone has been inserted either for decoration or as some kind of fastening. 
4 The same work marks can be clearly seen on either side of the bone ? inserts.

6 The underside showing the bone with same worked surface, as the previously shown inner surface.
1 - This image shows a a Prehistoric Human tibia shaft outlined in yellow , before being fully excavated from the grey lake bed at Stainsby beck. To the right outlined in red some of the other none human bones are visible but most are still buried. I believe the two different Human femurs found at an earlier date just down stream, and the preserved leather moccasin type sole excavated and shown in an earlier post could all be related. 
2 - This image shows the excavated Human tibia shaft washed and dried .
3 - This image shows an artiodactyle Mandible, and maxilla piece, the teeth tell me this animal was a juvenile .
4 - This horn core was also excavated very close to the Human tibia shaft and artiodactyle pieces shown in image 3 .
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 .

6 - 9 Unknown horn core .

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 .
14 - Ugly but it fits !
