The forelimbs were longer than the hindlimbs, which result in a steeply inclined trunk, making the overall body shape reminiscent of a modern giraffe. Also, while the tail is a typical long dinosaur tail, it was relatively short for a sauropod… (read more: Wikipedia)

Aside from creating more of a cool visual for this raven-sized animal, the discovery suggests that Archaeopteryx could fly, since the color and parts of cells that would have supplied the black pigment are evidence that the wing feathers were rigid and durable. These are traits that probably would have permitted flight…
