Feathers or Scales

I think that some dinosaurs had feathers, like the smaller Dromeaosaurs, or the small bird-dinosaurs, and maybe a light covering for some of the juviniles of a limited amount of dinosaurs. But they mostly had scales.

Probably just the smaller and more bird like dinosaurs had feathers. Haven't there been skin imprints discovered that shows dinosaurs had scales?

There have been several of those cases, mostly for big dinosaurs, and feathers for the little dinosaurs.

The bird- dinosaur relation is still vibrant today. Infact, some birds still have the same hip joints as saurischians! Anyway, I think some dinosaurs had feathers, but I doubt that all dinosaurs had feathers. It does sound ridiculous

I don't think all dinosaurs were 100% feathery. Yutyrannus, a 30 foot long tyrannosaur, had feathers, but Carnotaurus, a comparably sized dinosaur, did not judging by skin imprints of the side and skull. We know that most, if not all, dromaeosaurs had feathers judging by well preserved imprints. Ceratopsians had protofeather quills on their backs as well. I don't think spinosaurs had them because they would do nothing in the water other than get wet and annoy the dinosaur unless they were like duck feathers and kept the dinosaur warm and dry. Ornithomimids probably had them, as well as the therizinosaurs and a few other families had them as well. Maybe not the first dinosaurs, as that's when they were branching off from reptiles, but still, it's possible that all dinosaurs, including sauropods, had some feathers somewhere. Maybe not probable, but possible. One example is humans. If some futuristic race discovers a skin impression of our elbow hundreds of millions of years from now they're not going to know we had hair on our heads or anywhere else for that matter because they won't be able to see that in an elbow impression. They'll probably use other primates as an example and depict us as really hairy like my grandpa.

I am all for leaving t-rex, raptors, and other dinosaurs already established in the movies featherless. But any new dinosaurs in the 4th movie that are known (or likely) to have been feathered in real life should have feathers in the movie.

Well,to me,some of them especially raptors should have feathers,the others like the big ones,maybe no.....but all kind of raptors,definitely!

Feathers would create a realistic Look to them, but it would not fit the story line. In the movie the Dinosaurs are genetically altered, Raptors are 3X larger than their normal selves. Unless the Dinosaurs have evolved over 20 years then it may not work. In the end, it would still be awesome either way!

Actually I never thought of it like that (What Troodon1 mentioned) I always was so furious on why the velociraptors were like HUGE! But as far as feathers go I think that most raptors (smaller species) may have had feathers under their arms, down the back of their hind legs, ontop of their heads (males) etc. But when I open a book to the velociraptor page and see a chicken with claws, I feel sick.

jurassiraptor and troodon1, I'm not talking about the movies, I'm just talking in general is all. And I do agree about some of the smaller dinosaurs like the dromeosaurs only having feathers and not the big ones like t-rex, carnotaurus, triceratops, brontosaurus, etc.

Almost, if not all the coelurosaurs, doubt I spelled that right, had feathers. Juvenile tyrannosaurs had them until they reached a certain size, probably about 16 ft or so. Raptors had em, except maybe Utahraptor. I say that because it was a pretty primitive raptor. Herbivores, except the therizinosaurs, probably did not have feathers and the big carnosaurs probably did not either, except maybe a few here and there. If they did, the carnosaurs that is, it was probably a few feathers on the arms or head, nothing more.
