What colour were the dinosaurs?
Because large modern-day warm-blooded animals, such as elephants and rhinoceroses, tend to be dully colored, many scientists think that dinosaurs were, too. But other paleontologists say the opposite is true — that dinosaurs' skin could have been shades of purple, orange, red, even yellow with pink . Nov 17, · 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. They started as brown, green, or pale white giants with rough scaly skin roaring in the rain. We now know that many dinosaurs at the end of the Cretaceous, like Anchiornis huxleyi, actually had feathers!Estimated Reading Time: 6 mins.
A Scholastic Professional Book. While skin impressions have been found — suggesting a pebbly or scaly texture — no real dinosaur skin remains. That means paleontologists don't know for certain what color any of the dinosaurs were. They do have several theories, though. For wyat, many believe that dinosaur skin was probably drab shades of gray or green, allowing them to blend into their surrounding environments.
This dull coloration would help them escape the detection of predators, enabling some to survive longer. Because large modern-day warm-blooded animals, such as elephants and rhinoceroses, tend to be thw colored, many scientists think that dinosaurs were, too.
But pak choi how to cook paleontologists say the opposite is true — that dinosaurs' skin could how to decorate a vintage silver christmas tree been shades of purple, orange, red, even yellow with pink and blue spots!
Rich and varied colors, they argue, might have helped dinosaurs to recognize one another and attract mates. Because research has shown that dinosaurs'closest living relatives — birds — can see in color, it is theorized that dinosaurs could, too. Scientists in this camp believe that color may well have been as important to these ancient creatures as it is to us. Jack Horner, Curator of Paleontology at the Museum of the Rockies, Denver, Colorado, explains, "Some male dinosaurs may have had brightly colored crests to help dinosaure attract mates, but females probably did not.

We know a lot about dinosaurs. But this question has stumped scientists for decades.
May 11, · As with other dinosaurs, scientists and artists have never known what color to paint it. Analysis of the skin using a synchrotron at Canadian Light Source (CLS) may offer a clue about what color this duck-billed dinosaur was. Physicist Mauricio Barbie said, “As we excavated the fossil, I thought that we were looking at a skin bantufc.com: Dr. Elizabeth Mitchell. Mar 14, · By comparing melanosomes in fossil feathers with those of modern birds, we can get an idea of what colors some dinosaurs were. The little dinosaur Anchiornis looked something like a magpie with a punk-rock crown of red feathers, for example, while the armored dinosaur Borealopelta was rust red on top and light below — counter-shading that would have helped this herbivore blend into its Author: Riley Black. Aug 11, · By looking at these shapes, scientists were able to determine nearly the full color of the animal (though there are uncertainties about the tail). Anchiornis was primarily black and grey with white stripey patterns on its wings. The striking piece of color on the almost bird was the crest of red feathers on the animal’s head.
When I was a wee lad who was very into dinosaurs, I always was troubled by a question about my favorite group of animals: What colors were the dinosaurs? See, we could look at teeth and stomach contents to see what they ate, we could look at the leg structure and footprints to see how they moved, and we could even look at the internal bone structure to see how they grew.
But despite knowing so much about these animals, we still had no idea what they looked like. Luckily for those interested in the most majestic of beasts, the past few years have been incredibly eye-opening to the paleontological community. Some things you may have missed include:.
But the one that gets a lot of people is that nowadays tons of dinosaurs are being depicted with feathers. My buddy Ethan thinks that Velociraptor was actually scarier with wings, because of a theory that like many modern birds of prey, raptors may have flapped to help keep balanced on top of larger prey while they slashed at them with their enlarged toe claws.
And, Answers in Genesis , stop saying that those clearly imprinted feathers with vanes and rachis are just collagen fibers that somehow happen to form the shapes of wings and tail feathers on many dinosaurs.
The study of feathered dinosaurs has revealed many interesting secrets, but the one most appealing to my child-like dinosaur interest is the existence of trace pigments among the feather imprints in four different dinosaurs, giving us a glimpse into the world in which dinosaurs lived and their manner of surviving within it.
I will go through these four dinosaurs and their colors, but I want to point out something important to note. All of these dinosaurs, being feathered, were closely related to those that would become the ancestors to modern birds.
Some might argue that some of these dinosaurs, particularly one, are birds. Really, the separation between dinosaurs and birds is iffy and the change between them is gradual, with not all the features changing in a particular instant, so scientists have trouble deciding where to draw the line. Part of this challenge stems from the fact that they have traditionally all used Linnaean classification kingdom, phylum, class, etc… but evolutionary biologists are starting to prefer a cladistic system of classification in which organisms are classified by clades, the sets of all organisms descended from a particular common ancestor.
In the Linnaean system, the division between birds and dinosaurs is based on what features you use to define the two groups. I will not consistently use one system or the other, because I think they both emphasize different points of importance. Of the dinosaurs for which we have evidence of specific colors, the one we know best was unearthed in in the Liaoning Province of China. Dating back to the Jurassic Period about million years ago was the fossil of Anchiornis huxleyi. Anchiornis was a small little sucker, measuring just over a foot in length.
It sported a long tail, switchblade claws like Velociraptor , and feathered wings. Close examination into the contents of the feather imprints showed traces of melanosomes, pigments that also exist in modern bird feathers.
The shape of each melanosome determines the color it will make the feathers. By looking at these shapes, scientists were able to determine nearly the full color of the animal though there are uncertainties about the tail. Anchiornis was primarily black and grey with white stripey patterns on its wings.
If you know anything about birds, you know that colorful features are very often to attract mates. In most animals alive today, it is the males that do the attracting with their flashy features, crazy dance moves, or violent attacks on each other.
Perhaps Anchiornis rocked out with crazy head bobs or something else sexy. Variations in physical characteristics between the sexes of a species is known as sexual dimorphism. For an example of this, think of a chicken. Sexual dimorphism is incredibly hard to determine in dinosaurs.
Having only the bones, it is difficult to know if two different but similar specimens are two related species or simply the male and female varieties of the same species. Usually, paleontologists assume the more likely and guess that they are distinct species. But it is still entirely possible, especially when dealing with color and feathers, that the two sexes could have had wholly different phenotypes.
Another interesting question arises from the idea that Anchiornis may have used its bright crest for courtship. Crests are a very frequent feature among dinosaurs. From the trumpeting Parasaurolophus to the Dilophosaurus that Jurassic Park decided to give a spitting ability, many dinosaurs had elegant headgear and perhaps they had bright colors on them too. Of course, this is only speculation, as is the idea that Anchiornis or any dinosaur used bright colors to attract mates.
It had the body shape, skeletal structure, long tail, teeth, and claws of a theropod dinosaur, but the wings and feathers of a bird. The mystery of where birds fit on the great tree of life was solved. Was it a bird or a dinosaur? It was not a singular jumping point but simply part of a spectrum with scaly dinosaurs at one end and modern birds at the other.
Archaeopteryx lived in the late Jurassic Period million years ago, meaning that feathers had been around for a while, but full-fledged birds were still a ways off. So the idea that Archaeopteryx is the single most important link does not really respect its place in the evolutionary ladder. Archaeopteryx is classified today as a maniraptoran dinosaur, part of the same group that includes Velociraptor.
Although the ancient wing was originally assumed to fly, scientists have come to realize that its wings were not developed enough to generate powered lift, though the animal may have been able to glide short distances.
Archaeopteryx lived at a time when sea levels were much higher and consequently Europe was flooded in many areas, creating various islands with large lengths of seashore that the feathered dinosaur could pick for food. In , scientists analyzed part of the imprinted wing feather of an Archaeopteryx.
They found that it was full of traces of a copper pigment which in modern birds produces a dark color. A newer study in looked at the entire feather and realized that it was actually light in color, but was only dark on the end and around the edges. The reason for this is not something that I would have thought of off the top of my head. Apparently, in modern birds, copper pigment acts as an antibacterial and helps keep mischievous bacteria from fraying the edges of the feathers.
Of all the dinosaurs I am going to talk about, Sinosauropteryx is the least bird-like. The little creature measured about four feet long and lived in China about million years ago on the edge between the Jurassic and Cretaceous periods. However, the part that interested scientists most was the tail of the three-foot long dinosaur, which had bands of melanosomes with empty areas in between. This suggested stripes.
I would totally get Sinosauropteryx -print merchandise out the wazoo. But when we look at the colorations on leopards, zebras, and giraffes, we have to realize that these all serve practical purposes for the animals. So what did Sinosauropteryx use its stripes for? There are a lot of theoretical purposes, but the main two are probably pretty obvious: camouflage and sex.
Look at me! Tigers today use their stripes to camouflage among vegetation as they stalk unwary prey. The light-and-dark pattern on their skin mimics the light-and-shadow of plants, meaning that the tigers blend into their surroundings.
Maybe Sinosauropteryx used its stripes to hide from predators. Measuring only two feet long, Microraptor was built to live in trees. And, yes, it was a true raptor, or as scientists put it, a dromaeosaur.
But what makes the little thief stand out among dinosaurs is the level of development in its wings. A lot of feathered dinosaurs may have been able to glide short distances, but rarely did they have fully developed flight feathers like modern birds. Microraptor , however, outdid modern birds by having not just two, but four wings with fully developed flight feathers. The little thief did not have the muscle power for powered flight, so it did just glide, but its brilliantly crafted body allowed it greater control than most gliding animals.
Microraptor could have held its forewings up to support itself in the air while its back wings would have been held downish for use as rudders, making it sort of like an X-Wing Fighter from Star Wars , I suppose. This would have given the animal expert steering and possibly to some extent even a swooping ability. Fish bones found inside the gut area of a fossilized Microraptor along with forward-angled teeth indicated that the animal was at least partly piscivorous.
Perhaps it swooped over lakes and snatched fish from the water. Microraptor tended to be portrayed by paleoartists in weird shades of brown, blue, and green for some reason or other. Its unique four-wingedness made it popular among dinosaur fans. But in , the little bird-dino was found to be a lot prettier than the raggedy crude-looking feathered nightmares spawned by the paleoartists. Analysis of melanosomes in a well-preserved Microraptor specimen revealed that the structure of pigments in the little thief was similar to that of birds with black glossy feathers.
The use for these feathers is a huge topic of debate. The animal was a glider, of course, but the gloss must have had another purpose. Of course the topic of attracting mates shows up. Maybe male Microraptor made a flashy show for the chicks. But some scientists have pointed out that the gloss might be an accidental side-effect of feathers designed for another purpose. After all, some animals like moles have glossy coats even though they rarely have light shining on them at all.
One idea is that the chemical nature of the feathers resisted moisture soaking in. Of course, this is highly speculative and there remains a lot of mystery with very few easy answers. What do you think? Other than birds, these are the only four dinosaurs whose colors are at least partly known to science. The explosion of interest in dinosaurs could lead to more discoveries in the near future. Special thanks to Ethan Schmunk who illustrated these wonderfully accurate pixel-art depictions of feathered dinosaurs.
Jacob is an amateur historian and utter nerd from the state of Oregon in the United States. He is incredibly fond of the ancient world, mythology, China, and dinosaurs and would probably be very happy to sit and talk with you about why Julius Caesar was a boss or why Therizinosaurus is greater than whatever other animal you might want to compare it to.
