Thoughts on these allosaurus bones in matrix? debating whether it is worth to try prepping the bone.

[jacob86795]

 These bones are confirmed to be real allosaurus bones, just wondering if it would be worth it to prepare them although they are not in the greatest condition.

Your photos are way too small for us to see anything. Your image provider must offer you a link to see your photos in the correct size.

 here is a larger photo of the bones, which is lighter than the surrounding matrix.

My suggestion is to leave them in the matrix and just expose them a little and clean them up.  They are fragments so I think the two together are more interesting than if separated.

[jacob86795]

will do that then, do you have any suggestions for what vinac I should use once the bones are prepped? Pretty sure I still have some Paraloid B72 and Butvar B76 left over that I can use as there are a lot of cracks. Also it seems to be an arm as the bone on the right seems to be a partial humerus missing its distal end.

I use Vinac or B72 but you cannot go wrong with either ones you suggested for your application.  Don't forget to hardened the matrix to keep it from crumbling over time.

what would you suggest to harden the matrix?

I'm not a prep person but have used the same consolidants.  Let's see what others say.

It is very hard to tell from these phots what the matrix is.  I can't even see the bones.  Many Morrison Fm bones come in matrix that does not need consolidant, but I could give you  better answer with some better photos.

here is a better image

Can you take a photo of the back side so we can get a good view of the matrix

That matrix looks pretty stable.  I would not put anything on it.  (As seen from here).
