Many dinosaurs and while pterosaur super Feather FlamesEarly mammals were a sad lot. A study of six mammals living in the days of Jurassics and Cretaceous has had a skin brown skin.
“They were dinosaurs food,” he says Matthew Shawkey Belgium at Ghent University. “You didn’t want to notice.”
The animals living in the distant past believed that the animals were impossible. But since the 90s, thousands Fossils with feathers and skins are found.
In some cases, Melanosom traces – Organies with pigmental pigment – These fossils can be seen under a microscope.
Melanin comes in two varieties – black and red brown – and Melanosomes change in shape depending on their composition. So knowing the form of melanosomes in leather or feathers gives you a good idea of their color.
Shawkey’s team started watching Melanosomes in the leather of 116 many dead mammals. From there, the researchers developed a model that announces the form of leather color that has formed MelanosoMan and have applied six fossils of different early mammals.
All six fossils came from the same deposits in China, but the species lived at different times from the central Jurassiko, about 165 million and 120 years ago. One of them was a mammal described mammal Arboroharamiya Fuscus lived about 159 million years ago.
Given that all these mammals have been thinking of nights, it is not surprising.
“We expected to have enough enough colors,” Shawkey says. “The only thing I was surprised was how unchanged. They were more similar than what the colors would announce.”
The team intends to spread his examination from any other part of the world in search of more fossil mammals, but Shawkey has no results for much different. After the dinosaurs disappeared 66 million years ago, many mammals became active during the day and that probably became a variety of colors.
Some fossils of dinosaurs and Maritime reptiles are preservedBut few attempts have been made To work on the color of the skin fossils.
