It’s the first molecular evidence of phaeomelanin, the pigment that produces ginger coloration., in the fossil record.

“Fossils are invariably altered by the ravages of heat and pressure during burial, but that doesn’t mean that we lose all original biomolecular information. Our fossilization experiments were the key to understanding the chemistry of the fossils, and prove that traces of biomolecules can survive being cooked during the fossilization process,” said Professor McNamara, senior author of the study.Evidence of fossil phaeomelanin has been elusive.
