This stops animals standing out from their background, making them harder to spot, avoiding detection from would-be predators and potential prey.Behavioural ecologist Professor Innes Cuthill in previous studies showed the precise pattern of countershading relates to the specific environments in which animals live.The new analysis reveals it had a ‘bandit mask’ across its eyes, just like today’s raccoons.It also had a light-colored underbelly, a dark back, and a striped tail.While the Chinese dinosaur had multiple types of camouflage to avoid being spotted by larger predators, including relatives of the infamous T-Rex, the black eye mask also allowed the sneaky creature to creep up more easily on its own next dinner.An analysis of fossilized feathers on the dinosaur called Sinosauropteryx revealed a camouflage pattern that included a bandit mask, a light-colored underbelly, dark-colored back and a striped tail.Scientists have reconstructed the color patterning of a small, feather-clad dinosaur that roamed China 130 million years ago – and, they say it shared a distinctive trait with the furry modern mammal that topples trash cans in North America.

Previous research indicated its dark feathers were brownish-red The study involved mapping out how dark pigmented feathers of three specimens were distributed across the body and revealed some distinctive colour patterns also seen in modern animals.The color pattern suggests the landscape was an open savannah rather than a forest.'This was quite a surprising discovery,' Smithwick said.That feature may have given Sinosauropteryx certain advantages.For example the dark stripe around the eye is seen in modern birds to help them to hide the eye from would-be predators, and a striped tail that may have been used to confuse both predators and prey.Once the researchers reconstructed the colour pattern, they created 3D models of the dinosaur and photographed them under different lighting conditions to see where their colouration would have hidden them best from potential predators.
