Are you saying the refusal to entertain dinosaur soft tissue over 65 million years old is not because of a belief?
All you have is the empty assertion that soft tissue can't be preserved over 65 million years old. The dinosaur bones themselves are found in very well dated sediments in the Hell's Creek formation (if memory serves).

"It is hard to imagine for anyone trained in the rigor of science that Wieland could offer as an apparent concession the notion that "Some dinosaur fossils could have formed in post-Flood local catastrophes." It is hard to imagine Wieland is serious when considering that by "post-Flood," he means that there are dinosur remains floating about that are less than 4000 years old. What is inconceivable is that Wieland is honestly ignorant that the dates associated with the age of these remains are not related to their condition. The age of the specific
T. rex bone which was the principle database for Schweitzer
et al is not based on either its macro- or microscopic appearance but of the age of the rock that it was found in,
"... the base of the Hell Creek Formation, 8 m above the Fox Hills Sandstone, as an association of disarticulated elements." The appearance of soft tissue, hard tissue or no tissue has no bearing in the age of this material- organic or inorganic. What is the basis for these age determinations is the independent existence of geochemical "clocks" known as radiometric dating. Professional creationists and their prey simply reject radiometric dates, which has always seemed to me to be an odd logical contradiction, or in an anthropological term: cognitive dissonance. If these people are able to ignore geology, chemistry and physics, why do they even bother to lie about biology?"

Notice the measurements of tektites, biotite, and zircons in the Hell Creek formation in that figure. We have three different minerals measured by three different radiometric methods all producing the same date. The age of the fossils is not in question.
