I discovered this half buried mineralised carcass today on the banks of the old river Tees in Middlesbrough Cleveland North East England. But only had a poor phone camera so the images aren't great, the animal seems to have died were it is now, I aim to excavate it tomorrow, and will report my findings.

I am now in the process of cleaning and preserving the skull and mandible.
The pics below show the piece after a basic clean, this Equus piece shows no signs of use by man either for transport or work.

I have tested for magnetic content and again have found this skull and mandible like a lot of other mineralised bones excavated in the south west of Cleveland attract a magnet, as ive stated before I believe this is because the animals absorbed some form of Magnetite, either when alive or during burial.

Note the round magnet attached to the bone outlined in red.

2 - This image sows the damage i believe must have been caused by a blunt impact.
3 - It is possible the damage was done by rubbish in the river flow, but i think this is unlikely as there is no other damage to the jaw or skull.
4 - This looks deliberate and not modern in any way.

1 - The first 3 images show two none rare earth magnets attached to an Equus radius recently found in Stainsby beck in the south west area of Cleveland North East England.
2 - This Radius has one of the strongest magnetic attractions, of the many magnetic bones and wood Ive found in this area, usually the wood or bone will only hold a rare earth magnet, not weak ones like this.
3 - This bone is well mineralised and as with the wood and bone Ive previously reported to have a magnetic attraction. I believe the bone has absorbed some form of Magnetite, either after burial or possibly even while the animal lived.
4 - This image shows a much stronger rare earth magnet attached to the same radius.
5 - The next images show another Equus radius from another beck valley area in this area with a rare earth magnet attached, this bone would not take a none rare earth magnet.

1- The three images show a split and polished Septarian nodule from the Stainton gravel beds.
