We can, in fact, determine the coloration of dinosaurs , given well-preserved specimens. Most of these have been pigmentation of feathers. Microraptor had iridescent black feathers like modern crows, Anchiornis had black, white and grey feathers all over its body and a crest of dark red or ochre feathers on its head, and Sinosauropteryx had rusty orange feathers over its body and white rings on its tail. However, we have been able to discern the pigmentation of a couple of non-feathered dinosaurs. Psittacosaurus was counter-shaded (dark back, pale belly) and had stripes and spots resembling camouflage patterns seen in some modern animals such as certain deer. Borealopelta was also counter-shaded in shades of brown.
