Answer #1

Actually, no - fossils are no longer the original material, but are rather totally replaced by minral deposits. Preservation of soft tissue - and hence DNA - is very rare indeed. Details here: http://en.wikipedia.org/wiki/Fossil#Types_of_preservation

Answer #2

‘tis a serious question, aparently the bones become crystalised due to pressure however I’m pretty sure that’s wrong. So to elaborate, would you be able to retrieve a full T-rex DNA from bones or bone marrow?

Answer #3

is this a serious question? they wouldnt be called dinosaur bones if they werent bones

Answer #4

In the antarctic or a tar pit you might if it was preserved well enough It would be incredibly rare though

Answer #5

Yes and yes but they have become fossilized so it does not contain complete DNA anymore

Answer #6

Older bones are fossilized, meaning they’ve been replaced with stone. The stone comes from what’s dissolved in ground water.

Answer #7

actualy most bones have been found to have a lot of soft tissue in them still, using a chemical prosses that does something to them (I don’t know wht it is) the tissue is “resoftened” and there is a lot of DNA in it
