Hard to get more chemically different than that. On the other hand older fossils are often made of minerals deposited in an imprint, or that have permeated the bone (eventually replacing it entirely). In this case it's structure and chemical content as opposed to the (largely sedimentary) rock around it helps to distinguish between the two. There are lots of things that look like fossils that aren't.

They contain bone structures recognizeable by any anatomist, and are found in strata recognizeale by any geologist worth his salt. There is no doubt whatsoever that dinosaur fossils are real amd are very old.
So it IS as I suspected ....even the chemical composition of the Dinosaur bones are proof that they are not fake and are definitely bone?
