Dinosaur rib bones reveal remnants of 195-million-year-old protein
New research provides the first evidence that proteins have been preserved within the 195-million-year-old rib of the sauropodomorph dinosaur Lufengosaurus.
...The collagen was found together with lots of small, spherical hematite particles. Hematite is a mineral that can be formed from the iron in hemoglobin, the oxygen-transport protein in red blood cells. The chemical bond between iron and oxygen is what gives blood cells their red colour.
Reisz and his colleagues believe that these hematite particles were derived from the original blood of the dinosaur, and that they acted as the catalyst for preserving the protein in the vascular canals of the bone. These collagen pieces are probably remnants of the blood vessels that supplied blood to the bone cells in the living dinosaur.
"Interestingly, there was no evidence of preservation of organic remains in the main mass of the bone, only in the small vascular canals that ran along the length of the rib, where hematite was also present" says Reisz.

I would say that you weren't aware of the various dating methods that led to that figure

Carbon dating is not used to date fossils.
Bone contains proteins which contains carbon.
Regardless, Soft tissue is found in dinosaur bones; Schweitzer found collagen and blood vessel fragments in tyrannosaurus bones.

Carbon dating (and when it is/is not used) has been explained to you a million times before. If you haven't grasped it by now, give up.

No.
I want you to go back to your faith and religion forum and leave people who are interested in science free to talk about the science.

Abstract
Fossilized organic remains are important sources of information because they provide a unique form of biological and evolutionary information, and have the long-term potential for genomic explorations. Here we report evidence of protein preservation in a terrestrial vertebrate found inside the vascular canals of a rib of a 195-million-year-old sauropodomorph dinosaur, where blood vessels and nerves would normally have been present in the living organism.

Give up?
Seriously, seriously, you believe,
collagen in 185 million year old bones, you believe that, you actually believe that
Is there anything a man in a white coat talking about dinosaurs and evolution you would question, anything
Seems stretching the creditable is now considered authentic science
Collagen in bones 185 million years old, talk about confirmation bias, you have to believe, you have to believe
You say that Cooperton has confirmation bias but Cooperton doesn't have to believe, yet get hyped, Vlar, crow, you all have to believe, you have to believe the man in the white coat is telling the truth, you have to believe, you can't not believe, it's imperative you believe, demanded of you and you all are servants to confirmation bias
As a Christian, I don't lose my God if I choose evolution, on the other hand, evolutionists have no choice, you are loyal subjects to what you are demanded to follow,
collagen in 185 million year old bones, confirmation bias,
185 million year old bones with collagen.
185 million year old bones with collagen, I can't repeat that enough, it's so stupid it needs repeating over and over again
Carbon dating is not used to date fossils
Carbon dating is not used to date fossils
Fossils don't have collagen in them
Fossils don't have collagen in them
185 million year old bones with collagen in them are not 185 million years old, something is wrong, stop drinking the cool aid
