Early dinosaurs probably looked a lot more like Big Bird than scientists once suspected. A newly discovered, nearly complete fossilized skeleton hints that all dinosaurs may have sported feathers.
It suggests that the ancestor of all dinosaurs might have been a feathered animal, says study author Mark Norell, a paleontologist at the American Museum of Natural History in New York.
Researchers have found feathered dinosaurs before, but this one is more distantly related to birds than any previously discovered. Called Sciurumimus albersdoerferi, it belongs to a group of massive dinosaurs called megalosaurs that had sharp teeth, claws and a heavy-duty frame. The specimen a youngster that lived about 150 million years ago is only 70 centimeters long, but it could have grown up to 10 meters, about the length of a school bus.

'All dinosaurs' does seem a stretch; but they're saying it's unlikely feathers developed twice, so it pushes it back to the middle Jurassic most likely, anyway, and it might go further; and raises the possibility that allosaurs had some form of feathers too.

I am not entirely sure how they have determined this, but then again, I am not an evolutionary researcher. What this does mean, if it turns out to be true, is that many adaptations may have developed more than once.

(53,521 posts)Dinosaurs and Pterosaurs are sister groups, so their common ancestor probably had those hair-like structures.
