Has anyone heard the LATEST reasoning behind the tissue being soft after 65mil years?

According to the people who found the tissue (Schweitzer et al) it was mineralized. This would rather preclude people, or at least sane people, from offering reasoning to explain why it wasn't.

Well, he didn't know it wasn't soft, which he could have found out by glancing at the abstract of the paper.

I was not aware the smithsonian mag was religious. Noted Here is the link I was reading:

History, Travel, Arts, Science, People, Places Smithsonian Magazine

Now that link describes the demineralization process, and also describes how creationists lie about Schweitzer's work. So how carefully were you reading it?

I bring it up here, hoping people have more information. The articles are written for the general public and have stated "red blood cells", etc. It makes it easier to track down the associated articles by asking those that are interested, then it is to google and go through 100 articles.

Yes, other people can use google for you.

From the abstract of Schweitzer's paper:

Soft tissues are preserved within hindlimb elements of Tyrannosaurus rex (Museum of the Rockies specimen 1125). Removal of the mineral phase reveals transparent, flexible, hollow blood vessels containing small round microstructures that can be expressed from the vessels into solution. Some regions of the demineralized bone matrix are highly fibrous, and the matrix possesses elasticity and resilience.

Wow! This is the first time you replied to me without name calling or rude comments

This is, of course, not true.

Thanks. It was actually a really good explanation.

You're welcome.
