Protopteryx fossils show that they were roughly the same as a today's starling.[6] The adult body length of the Protopteryx was about 10 centimetres (3.9 in), excluding the tail feathers. Protopteryx teeth were conical and unserrated, and some teeth had a resorption pit similar to those seen in Archaeopteryx. The body of the Protopteryx was covered in three types of feathers: down feathers, flight feathers, and long, ribbon-like tail feathers. The body was mostly covered in feathers of about 12 millimetres (0.47 in). The barbs of the down feathers were laminar instead of hairlike and were frayed at the tips. The most distinctive feature of the Protopteryx is that the tail consisted of two long feathers which only had barbs at their tips. Closer to the body, the long tail feathers were thin

The most distinctive feature of the Protopteryx is that the tail consisted of two long feathers which only had barbs at their tips. Closer to the body, the long tail feathers were thin and needle-like. The only modern birds to share a feather type similar to the Protopteryx is the red bird-of-paradise. The tail feathers also lack rami on the proximal end of the tail.
