Well, I am surely having trouble sleeping tonight. You can tell from these questions, and my rambling on in the Member's Only Forum.... Ok, so I am base painting the Carnegie Quatzacoatlus, or whatever, and I notice the body is sculpted as having feathers, or down or whatever. It's fluffy! Is this accepted reconstruction now? I know they are not dinos, so where do fluffy pteros fit in?And I know, this question is liable to ruffle feathers!--so keep it civilized, please!  |

en.wikipedia.org/wiki/Pterosaur"Hair Pterosaurs were unique among reptiles in that at least some of them were covered with hair, similar to but not homologous with mammalian hair. Pterosaur "hair" is not true hair as seen in mammals, but a unique structure that developed a similar appearance through convergent evolution. Although in some cases fibers in the wing membrane have been mistaken for hair, some fossils such as those of Sordes pilosus (the "hairy demon") do show the unmistakable imprints of hair on the head and body,[11] not unlike modern-day bats, another example of convergent evolution. The presence of hair (and the demands of flight) imply that pterosaurs were endothermic (warm-blooded)."

Kevin, that theory is not new at all, it's been known for quite a while  |

MMM, i saw a show on PBS where they tried to make a robotic ptero, to see how it flew, and they put a pelt on it. It crashed. It did much better bald. Just saying....

^^^ well, it wasn't as furry as a bat.  Just some light stuff on the body. |

Remember reptiles weren't always the same as they are today. Think of synapsids. They were a cross between mammals and reptiles.

Yeah, this idea has been around for a while... Imagine how cool a fig of one of these would be:  |

^ Look at old dinosaur books. The pterosaurs are illustrated with fur.

I don't have any old dino books...I don't remember them clearly, it was long ago, and my memory is shot, otherwise I'd give you yung uns a run for your money...
I never used to be interested in the pterosaurs or marine reptiles, it was all dinos for me. That has changed, partly due to some nice figures out there. So, I don't remember much about the old images, llooks like i have some looking around to do...
I am thinking that if it is "hair", I should stick with the creams and browns etc, I don't think most animals have hair that is blue or green etc. Maybe a nice tawney color....hmmmm..
And don't worry. CT, the figure had bad paint wear, so it was already blemished...

Tawny color would look nice.

It should be remembered that fur, scales and feathers are all really the same thing, a ceratin coating that protects/covers the body of vertebrates.
In the case of pterosaurs, it is probable many may have not had fur or hair at all. It has everything to do with climate, just as we see with mammoths, in cold northern climates with their coats of fur, and elephants in hot climates that are nearly hairless.
It is very probable then, that even the dromaosaurs/raptors in hot climates look exactly like they were originally depicted - without feathers.
In 1:40th scale, hair/fur would not even be discernable. On larger scale models however, one way to do this is 'flocking'. I believe you can actually get this in a spray can. I may do this to a large scale animatronic 'toy' pterosaur that blinks, flaps its wings, opens its mouth and turns its head.

Because the birds that live in deserts today lack feathers ? ...last I looked...they didn't, as even the ostrich, who does have bare patches to maximize heat loss when its needs to, has plenty of feathers to protect from cold desert nights and scorching desert sun...
I know this will never end until we out an out agree with lippy scaly dinosaurs....but for some reason I persist..., science be dammed, right ?

And again,you fall in the same,old error of judgement...Birds ARE dinosaurs,but dinosaurs ARE NOT birds,what works for birds could have not worked the same way for dinos and viceversa |

Well all the dinosaurs are not birds, what works for the dinosaurs who are birds could have worked the same way for some dinosaurs who were not birds. And there is not more reasons to believe that what works with today's reptiles could have worked with dinosaurs, because they are not dinosaurs.
Elephants are not hairless, neither human beings. Monkeys have furs and I've never seen one living in Groenland or Alaska as human beings do. I forget the zoo. Perhaps the raptors in hot climates had a lot of feathers on their head like lions nowadays have furs. I don't say that lions are birds or dinosaurs but the climate is not the problem. There is chances you've got feathers or furs if your grandparents already had them. The question is who is the first we can say that its scales can be named feathers or hair. We just don't know yet.

Remember though, dinosaurs aren't birds. Birds are dinosaurs. |

Some dinosaurs were birds. The birds-alive-today are dinosaurs and they are birds. |

This is true to a point. It is untrue to say that dinosaurs were birds though. Those "birds" were very close relatives of dinosaurs. Its a bit confusing, but no dinosaur was a bird, only birds were dinosaurs...some very close...
