This has enabled multiple full-body reconstructions of dinosaur colouration, such as for Sinosauropteryx [83] and Psittacosaurus [84] by Jakob Vinther and colleagues, and similar techniques have also been extended to dinosaur fossils from other localities. [80] (However, some researchers have also suggested that fossilized melanosomes represent ...
