PRESERVED DINOSAUR SKIN
_______________
A well-preserved specimen of the Psittacosaurus dinosaur species was found in Jehol biota of China. [1] The extraordinary preservation of the dinosaurs soft tissues, including skin, makes it noteworthy. The Psittacosaurus' skin tissues in the fossil have a pattern resembling small, spherical scales that cover its body and are many layers thick. Although it is not expressed in many of the articles on the tissues, they consist of unfossilized preserved skin containing collagen fibers which are a type of protein. The preservation of collagen under the most optimal environmental conditions is maximum 700,000 years before degradation destroys them. Yet, they are well preserved in this fossil putting the scientific date of 120 million years in serious doubt.
