Dinosaurs died out some 65 million years ago, so how could we possibly determine the color of their skin--or feathers? As Scientific American's Eric R. Olson explains, new fossil evidence is pointing the way.

http://facebook.com/ScienceReason ... What colors are dinosaurs? We may be closer to figuring this out. In August 2009, a team of researchers published the first evidence of color in a fossil bird feather. The scientists hope that eventually their study can give some color to feathered dinosaurs. No one wants to pass up a good dinosaur story, including us. The press has been all over this story, but I think its only the beginning I cant wait to find out Velociraptors true color. --- Please SUBSCRIBE to Science & Reason: • http://www.youtube.com/Best0fSciencehttp://www.youtube.com/ScienceTVhttp://www.youtube.com/FFreeThinkerhttp://www.youtube.com/RationalHumanism --- Structural coloration in a fossil feather Investigation of feathers from the famous Middle Eocene Messel Oil Shale near Darmstadt, Germany shows that they are preserved as arrays of fossilized melanosomes, the surrounding beta-keratin having degraded. The majority of feathers are preserved as aligned rod-shaped eumelanosomes. In some, however, the barbules of the open pennaceous, distal portion of the feather vane are preserved as a continuous external layer of closely packed melanosomes enclosing loosely aligned melanosomes. This arrangement is similar to the single thin-film nanostructure that generates an iridescent, structurally coloured sheen on the surface of black feathers in many lineages of living birds. This is, to our knowledge, the first evidence of preservation of a colour-producing nanostructure in a fossil feather and confirms the potential for determining colour differences in ancient birds and other dinosaurs. • Learn more: http://rsbl.royalsocietypublishing.org/content/early/2009/08/20/rsbl.2009.0524.full --- Since 1853, the California Academy of Sciences has been dedicated to exploring, explaining, and protecting the natural world.

If you get most of your information about ancient animals from vintage cartoons or action figures, then a lot of things that you think of as "dinosaurs" actually weren't. Learn about the definition of true dinosaurs and the evolutionary relationships shared by the non-dino reptiles that lived on land, in the sea, and in the air. ---------- Like SciShow?

Over the last few decades, paleontological artists have often adorned their depictions of extinct, non-avian dinosaurs with a rainbow of picturesque color patterns, in stark contrast to depictions from the earlier part of the 20th Century. In part, this shift reflects the scientific switch from viewing dinosaurs as drab relatives of crocodiles and lizards to viewing dinosaurs as closer relatives of birds. But is there any direct fossil evidence for this change? Well, the answer is no... and yes. No fossils of extinct dinosaurs, including "mummies" complete with fossilized skin impressions, have yet revealed the true color of the dinosaur's skin, at least in terms of what we usually think of as skin. There are fossils of a couple of turtles from the Cenozoic Era that are thought to preserve the pattern of pigmentation on the shell. Nonetheless, in terms of non-feathered dinosaurs, such as Apatosaurus and duckbills, no evidence for skin color has yet been found. Recently, however, a great wealth of astounding fossils representing small, feathered dinosaurs that are not birds has been collected in Early Cretaceous rocks in China, especially near Liaoning. Fossilized feathers, basically modified scales that grow in the skin, have been found on numerous specimens. In 2008, researchers discovered microscopic structures, called melanosomes, within fossilized feathers of an ancient bird. Different kinds of melanosomes create different colors in the feathers. Following this discovery in 2010, two teams of researchers reported finding melanosomes preserved in feathers of two, small, Chinese, non-avian dinosaurs -- Sinosauropteryx and Anchiornis. In the more comprehensive study of Anchiornis, in which 29 samples were analyzed from feathers all over the body of one specimen, revealed that this 155-million-year-old, feathered dinosaur, about the size of a chicken, possessed black-and-white stripped wings and a rusty brown crest of feathers along the top and back of its skull.
