I read the article. It doesn’t come close to saying they found DNA. They say they found something LIKE evidence of soft cells. In other words they found amino acids. Most fossils have no actual organic(read proteins, or amino acids). They do break down pretty fast in a regular environment(read surface of the earth). The writer of this article takes free license with what this discovery means. There are 3 types of fossilization. Mineralisation, encrustation, and englobement. The first two don’t leave any of the original specimen behind other than minerals and carbon(hense carbon dating). Englobement is where the specimen is airtight encased. Take a steak and put it in an airtight freezer and let it sit for 65 million years and you will have yourself a rather bad tasting steak but it will still be identifiable as a steak. This is the rarest form of fossil because over time the shell created around a specimen gets broken and the specimen destroyed. Now I don’t have access to the NC scientists original study but I’d be willing to bet that it was a case of englobement and that additional carbon dating will put that ole TRex right back where he belongs in the Cretaceous Period.
I must correct you on this. Carbon 14 dating only goes back about 50,000 years. For older materials, you need other forms of radiometric dating.

Correction: Carbon dating if they can do it, wont prove that T Rex was from the Cretaceous Period. Just way past what young earthers believe.
