I guess it's hard to describe an animal that has so much going for it in just a few words. In this case, this was the first clearly nonavian dinosaur preserved with what appeared to be filamentous precursors to feathers, but which was closely associated with dinosaurs that are bird like, which differentiates it from the also-fuzzy Sinosauropteryx.

But what's probably the first thing you'll notice is that the arms are so large, the feet large but short, and the claws HUGE. This is no mistake.

You may also notice the skull, which is based on a specimen with a crushed skull, but some details are clear, such as the shape of the anterior snout, and the general shape of the jaw bone, which helps us size this animal compared to the holotype in which ONLY the mandible was clearly distinguished.

The posterior skull is so heavily reconstructed that there is no way to tell what the shapes for the bones are, and the same is true for most the cervical vertebrae and dorsal vertebrae, of which only the last few are preserved (on the type specimen) uncrushed. Most of the vertebrae are based on highly questionable guesses and some comparisons and clear details with other segnosaurs.
