Low-aspect-ratio melanosomes in Sinosauropteryx filaments have been interpreted as It was the first non-avian dinosaur found with feather-like structures, providing further evidence for the link between dinosaurs and birds. The shape of melanosomes (tiny pigment packages in cells) in its feathers suggests it had a ginger body and white and ginger stripes on its tail. Its name means ‘first Chinese reptilian wing’. Sinosauropteryx, one of the extinct animals for which colour has been determined.

Melanosomes dinosaurs

Some dinosaurs were found with black feathers, while others had a rusty red color. How we see dinosaurs has changed drastically since Hollywood made them into superstars.

Many paleontologists suspected that dinosaur feathers also contained melanosomes. The Caihong (pronounced: kay – hong) dinosaur lived in China during the Late Jurassic. It is another small winged theropod dinosaur (about the size of a duck) that we’ve been able to determine its true colors based on the melanosomes found in its fossilized feathers. Its name, Caihong, literally means “rainbow.”

2018-09-12 · Long, narrow melanosomes produce grey or black colouration, Short, wide melanosomes produce rufous red, or brown colours, and; A lack of melanosomes, or melanosomes that are sparsely distributed, produce white or light colouration. Using this information, they predicted the colours of their dinosaur. 2014-02-12 · Melanosomes can be identified in fossils as well, and when Clarke and her colleagues looked at long-dead dinosaurs and pterosaurs (extinct flying reptiles that weren’t technically dinosaurs), they found a rich diversity of melanosomes in dinosaurs with true feathers, but not in species with the fuzzy filaments that preceded feathers.

Some dinosaurs were found with black feathers, while others had a rusty red color. How we see dinosaurs has changed drastically since Hollywood made them into superstars. But the discovery of melanosomes within the bristles finally proves that some early dinosaurs were indeed feathered" [ BBC News]. Dinosaur color is one of the unknowns in the field of paleontology as skin pigmentation is nearly always lost during the fossilization process.

New fossil research also suggests that pigment-producing structures go beyond Vinther published his initial findings in 2008, and then race to produce the first coloured dinosaur ensued, using the shape of the melanosomes to deduce hue and pattern.
