I have very little experience cutting dino bone but I got a nice 8 pound piece on ebay awhile ago and just got around to cutting on it. Every piece has a distinctive shimmer almost metallic looking. I guess I am wondering if this is odd or common and if it tells anything about the specimen at all?

Heres a video off my phone to try to show how light reflects on the dry slab

And this is a photo of the slab dry

This slab had s small red section. Wish there was more red but just one little spot.

Hopefully bhiatt can help shed a light on it.

Yeah I am a bit afraid of that but it already had a cut face and I only cut two slabs then stopped when I noticed the weird sheen to it.

Beautiful specimen of dino bone, Drummond Island Rocks!

I hope bhiatt will see your post and may be able to answer your question. I would keep the rest of it as a display specimen..

Here's his thread on manganese dino bone:

well I am by no means an expert but hematite shimmers when the light hits it just right. Pretty cool stuff. That is a great piece of dino bone.

Very, very cool! So weird, too, because I just dopped a scrap of bone I have that looks like it, too, has some hematite or pyrite. I can't wait to cab it- probably today. I'll post when I am done. I hope it cabs as cool as it looks now. -- I also hope that since you have that piece slabbed that you go ahead and make a couple cabs.

Thanks!
Hematite would be a great explanation for what I am seeing. I just did not know enough to know what is possible in bone. Looking forward to getting one cabbed soon.
