I have shown you where, in her own words, in a peer reviewed scientific publication she describes them as “demineralized”.
Are you ready to concede the point that this fossil was demineralized, or do you just want to dance around the subject?
You also have not answered by REPEATED question...
Why do we find bone of modern species, but only mineralized fossils of dinosaurs; if they all lived contemporaneously?
You are jumping to conclusions to defend your misperception.
You seem to be stuck on the older event, but even then, there was soft tissue that was not “mineralized.” And unfossilized eggs and bones of reptiles have been found several times.
