Cuenca dinosaur linked to birds

The most complete fossil of a dinosaur is Spain has been found in Las Hoyas dig in Cuenca. Concavenator corcovatus is a previously unknown species of carnivore that lived in the Lower Cretaceous some 130m years ago. El País

The beast sports a hump-like structure on its back hence its nickname “the humpback dinosaur”, and a series of small knobs on the forearm which appear to be a link to birds:

The bumps could be analagous to the parts of modern birds’ skeletons that anchor the flight feathers. Since the knobs are unlikely to be representative of feathers on Concavenator, the researchers propose instead that they are “non-scale skin appendages”, such as tubular filaments, present in modern-day poultry.
