For the First Time, Researchers Find Color Red Preserved in Fossil

The fossilized rodent, dubbed ‘mighty mouse’, is the first to show chemical traces of a red pigment in soft tissue

Reconstructed color patterns of Sinosauropteryx based on the pigmentation of fossil plumage. The dinosaur is portrayed in the predicted open habitat in which it lived around the Jehol lakes, preying on the lizard Dalinghosaurus.
