Science Daily has a story about another discovery of organic molecules in dinosaur bones. Since the early 2000’s, paleontologists have been finding organic material in dinosaur bones. The discoveries have been met with skepticism by paleontologists. Now a study in the journal Analytical Chemistry adds new evidence.

Professor Steve Taylor, chair of the Mass Spectrometry Research Group at the University of Liverpool’s Department of Electrical Engineering & Electronics, said:

“This research shows beyond doubt that organic biomolecules, such as proteins like collagen, appear to be present in some fossils.

“Our results have far-reaching implications. Firstly, it refutes the hypothesis that any organics found in fossils must result from contamination.

“Secondly, it suggests that cross-polarized light microscopy images of fossil bones, collected for a century, should be revisited. These images may reveal intact patches of bone collagen, potentially offering a ready-made trove of fossil candidates for further protein analysis. This could unlock new insights into dinosaurs — for example revealing connections between dinosaur species that remain unknown.

“Lastly, the findings inform the intriguing mystery of how these proteins have managed to persist in fossils for so long.”
