Blood vessels recovered from T. rex bone, dating methods may be flawed?

"Palaeontologists have extracted soft, flexible structures that appear to be blood vessels from the bone of a Tyrannosaurus rex that died 68 million years ago. They also have found small red microstructures that resemble red blood cells.

The discovery suggests biological information can be recovered from a wider range of fossil material than realised, which would greatly help the tracing of evolutionary relationships."

How could any "soft" tissue survive for 68 million years? Perhaps this Rex is a bit younger? Perhaps even 5000 years old? Perhaps there is a flaw in the dating metholology?

It's surely much older 5000 years. They're going to do research to find out how come it was so well preserved.

You may discuss further in this thread.
