Freddie would like help finding an explanation for this situation.

"Researchers found 'soft flexible nerve fibres and their unique wrapping' of a Triceratops (creation.com/creation 43(4):53 October 2021. This is the first time still soft and flexible dinosaur nerve fragment has been found. May I inquire how you think it has survived for at least 65ma?"

Why do you think it survived?

If you want to learn about dinosaurs the worst place to go is a creationist site.  The fibers found are microscopic and found with an electron microscope.  I would imagine that some small organic bits survived since the were encased in the fossilized bone and therefore protected from the environment.

Due to the long exposure to heat over millions of years, dinosaurs have become desiccated and decayed into an extremely fragile state. This is due to the fact that at high temperatures water molecules become unstable and dehydrate, causing their structure to collapse and shrink. When exposed to extreme heat, they eventually lose their volume and become brittle, like glass.

I'm not sure what you are talking about.  Dinosaur remains are not desiccated bodies, they are fossilized remains.  The tissue fragments found are encased in the fossilized remains.
