Did All Dinosaurs Have Feathers?

Maybe. The latest piece of evidence is this marvelous fossil from Germany. The animal is a young megalosaur of the species Sciurumimus albersdoerferi dating to about 150 million years ago. The tail shows clear feathers of the simple, threadlike sort paleontologists call Type 1. The megalosaurs were not far removed from the ancestors of all meat-eating dinosaurs, so the presence of clear feathers on this specimen suggests that the putative ancestor might have had feathers, too.
