This is just total b.s. While it's unusual for organic material to persist in older fossil samples, it's not unknown. Flies in amber last millions of years. Heck, amber itself is organic material. For decades, we have been dating biological samples by measuring the isomerization of isoleucine, an amino acid, over hundreds of thousands of years.
By the way, no one claims the Tyrannosaur material is 'perfectly preserved'. That's just you making stuff up, like the RANTING LIAR you are.
