Scales, feathers and dinosaurs
Article Abstract:
Evidences suggest that all coelurosaurs with the possible exception of gigantic species such as Tyrannosaurus rex are feathered based on the presence of feathers in some extinct coelurosaurs and all living birds. This new dinosaur, a carnivore named Juravenator, is represented by a beautifully preserved skeleton collected from Late Jurassic deposits from Solnhofen, Germany, the source of all specimens of the earliest-known bird Archaeopteryx.
