Submission + - Dinosaur Feather Color Discovered (scienceblogs.com) 1

anzha writes: Do you remember being a kid and told we'd never know what colors the dinosaurs were? For at least some, that's no longer true. Scientists working in the UK and China have closely examined the fossils of multiple theropods and actually found the colors and patterns that were present in the fossilized proto-feathers. So far, the answer is orange, black and white in banded and other patterns. The work also thoroughly thrashes the idea that fossils might not be feathers, but collagen fibers instead. If this holds up, Birds Are Dinosaurs. Period. And colorful!

Dinosaur Feather Color Discovered

  • Interesting, but probably jumping the gun on conclusions. Some pigments may have been preserved, but that does not mean that all relevant pigments were preserved, or that the relative quantities of preserved pigments are correct. Also, a great deal of color in modern bird feathers comes from interference effects (irridescence), which depends on small-scale geometry, not on pigments. The effects often occur in combination in birds.

Those who can, do; those who can't, write. Those who can't write work for the Bell Labs Record.
