More bone findes 3 Stainsby beck


























 1

All of these mineralised bone pieces where found in the same area of Stainsby beck that the two Human Male Femur where found.
 2 Cervidae or Bos Femur Proximal
 3This piece along with all of the others shown in this post had next to no residue attached, nor staining after recent heavy flooding i believe these pieces have been released very recently, and have spent very little time in the beck itself.
 4 The surface of the bone is in excellent condition, and as with most of the pieces i have found and excavated it has its own glossy shine once dried.

Magnetic bone and wood

 1
Images 1 to 4 show a piece of fossil wood, this piece easily pulled a rare earth magnet.

All of the mineralised bones shown in image 5 easily pulled a rare earth magnet. but when i attempted to do the same using a none rare earth magnet of the same shape and size, the bone did not pull the magnet.

 

My own ideas as to why the bones attract and pull the rare earth magnet, are either that the animals the bones belonged to somehow managed to absorb the magnetic material while eating, or the bones themselves absorbed the magnetic material after burial.
