Not sure how to ask but is dinosaur bone mostly heavy or light? I do have some and oddly they are extremely heavy. The shapes matched a certain anatomy area of a dinosaur. The material I find is premian-triassic to triassic along with material from devonian- Carboniferous. Nothing from Jurassic yet but a possibility when I do more homework. Area found will be discussed later but trying to figure out why so much material is petrified. Yes silica content is very high in area but bones almost look like iron shapes. I tested the shapes despite the color of black, brown, and smooth. And yes I was able to prove it's bone but not in a way one would think bone is preserved. No pictures for this discussion just trying to wrap head around why so heavy. Discuss this to get a better idea of preservance in an iron like way? The reason no pictures because not in a debate whether rock or bone but why heavy, ironish, brown and black.

Found this piece on a walk near a Triassic outcrop in Pennsylvania, has a pretty exact visual similiarity to the wing rib of a Triassic reptile but is likely just some form of sedimentary trace. It would be great to get some more opinions on this piece to see if its worth holding onto or I would label it to be definitely sedimentary and rid of it, which I feel is the case.
