I apologize for maybe stupid question ... I know there are studies on the colors of feathered dinosaurs by finding the true colors. But there peapers the POSSIBLE color of the Parasaurolophus?   |

There's no idea on what the coloration of Parasaurolophus was. So far paleontologists have been able to tell the colors of some feathered dinosaurs and even some fossilized insects, but not for non-feathered dinosaurs such as Parasaurolophus.

Thanks for the reply ... but I was already aware of this ... I was wondering if there are peapes where describe the plausible colors without to demonstrate this with certainty. |

Well, if you're going on that, the most likely coloration of P. walkeri would a lighter green (with a orange to yellow crest).

I believe there was a study that possibly found the colour of a certain theropod's feathers... but i'm not sure. Well, if you're going on that, the most likely coloration of P. walkeri would a lighter green (with a orange to yellow crest). why would that be??? do you have any evidence to back that up? |

Yes, Sinosauropteryx and Anchiornis. I got this information from the Princeton Field Guide to Dinosaurs. Gregory S. Paul displayed his dinosaurs (in this book) as a likely coloration of the actual animal, such as camouflage and display colors, but then again, this is just an educated guess. |

So you're saying that GSP's color schemes are always right? Quick, delete the post before he sees it and decides to copyright his color schemes too! ;D

Haha! No, but it's a pretty good bet to slightly go by his color schemes in the book, like to just go by the base color or something along those lines.

Well, some of GSP's color schemes are flat out impossible. He has outlandish things like bright purple on a dino with simple feathers (only possible in modern complex feathers), bright yellow or green feathers on carnivores (only possible in fruit or insect eaters), etc. So I would definitely not use those as a starting point. |

I don't see how these colrations are "impossible"

it's not that it's impossible, it's that say, bright green or yellow feathers on a carnivore is unlikely. they spent their lives hunting other animals, such bright colours wouldn't work well when trying to sneak up on prey.

Aw! Yeah, I could see how you see that. But there are many lizrards, like my favorite, the Kenyan Rock Agama ( Agama lionotus), are extremely colorful while still being predators. |

The reason why those colors would be impossible is that either the animal's feather structure or diet would not allow for it. Here's a good link about it. |

The reason why those colors would be impossible is that either the animal's feather structure or diet would not allow for it. Here's a good link about it. Correct. Green color in feathers is produced by a layer of blue iridescent structural color (requiring advanced flight feathers to begin with) over a layer of yellow pigment (which in birds and reptiles is gained almost exclusively through eating plants, or eating bugs that eat plants). So to have a green feathered dinosaur, the animal needs to be both an herbivore and an aviremigian. You'll notice that all green birds are herbivores--no green hawks, owls, etc. All geen and yellow lizards are either herbivores or insectivores, at least partly. Purple is due to an especially rare kind of iridescence, so again only possible (with feathers--scales are fine for iridescence) in aviremigians. Beipiaosaurus could not physically have been purple. Anyway my point is that a lot of artists don't take logic or biology into account when choosing colors, and this includes Greg Paul. He does not seem to have put any thought into how or why certain animals would be colored certain ways. So it is definitely a bad idea to assume his colors are correct. it's not that it's impossible, it's that say, bright green or yellow feathers on a carnivore is unlikely. they spent their lives hunting other animals, such bright colours wouldn't work well when trying to sneak up on prey. Aw! Yeah, I could see how you see that. But there are many lizrards, like my favorite, the Kenyan Rock Agama ( Agama lionotus), are extremely colorful while still being predators. Agamas are mainly insectivores, and they tend to be colorful because insects both eat a lot of pigment-containing plants and often produce good pigmentation themselves, which the lizards reproduce in their own skin. That combined with the fact that scales act the same way as advanced feathers (but not down, hair, protofeathers, etc.) in scattering light, means insectivorous and herbivorous lizards can be any color of the rainbow. |

And thank you for showing me that wonderful link! ;D |

Greg Paul is great for his skeletal reconstructions. Take everything else with a grain of salt.
What about snakes that are green? Insects aren't really a staple of their diet. Species like the Emerald Tree Boa or Green Tree Python start out as either brick red or yellow and then become green as adults. There are plenty of other species that are green their whole lives as well.

Yeah, what Griffin said. ;D
Also, as in lions, the females would go out and do all the hunting while the males lounge around looking pretty. I was reminded by this from Griffin's signature. Thanks!

I find it hard to believe emerald boas or any arboreal snake never take insects! As discussed in the blog, animals find unique sources for their pigmentation, like the carnivorous vultures that eat herbivore feces in order to produce yellow skin. |

But the only plausible time when I could imagine a Emerald Boa or Green Python eating insects is when they are hatchlings and thats when they are specifically not green. Then when they are adults (and green) they move on to much larger prey. Is it possible that when they are babies, they get enough insects to keep them green the rest of their lives?
