How about this article from National Geographic;

T. Rex Soft Tissue Found Preserved

Here is a quote from the article;

""To my knowledge, preservation to this extent—where you still have —has not been noted in dinosaurs before, so we're pretty excited by the find," said Mary H. Schweitzer, a paleontologist at North Carolina State University in Raleigh."

It certainly doesn't sound like this tissue was "mineralized".

Sorry, screwed up the quote;

"To my knowledge, preservation to this extent—where you still have original flexibility and transparency—has not been noted in dinosaurs before, so we're pretty excited by the find," said Mary H. Schweitzer, a paleontologist at North Carolina State University in Raleigh.
