Collagen, a protein found in bones and connective tissue, has been found in dinosaur fossils as old as 195 million years. That far exceeds the normal half-life of the peptide bonds that hold proteins together, which is about 500 years.
Chemists explain why dinosaur collagen may have survived for millions of years retrieved 4 September 2024 from https://phys.org/news/2024-09-chemists-dinosaur-collagen-survived-millions.html
