Help with Dino bone fragment

[GarbanzoBean]

I got this little bone fragment when I was a child from someone who said it was a hadrosaur bone from hell creek. Its always looked weird to me and I was wondering if it' s just another unidentifiable Dino nugget or if somebody could help me figure out what's going on here. Why does it look like there are two distinct regions fused together?

Looks like 2 unidentifiable specimens.  Lots of glue and matrix covering everything.
