Are dinosaur bones actual bone (and do they contain DNA)?
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#Typesofpreservation
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
'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?
Older bones are fossilized, meaning they've been replaced with stone. The stone comes from what's dissolved in ground water.
In the antarctic or a tar pit you might if it was preserved well enough It would be incredibly rare though
Yes and yes but they have become fossilized so it does not contain complete DNA anymore
is this a serious question? they wouldnt be called dinosaur bones if they werent bones
