The original description of Protoavis is not online. There are mentions of Protoavis in many different places including a short review of bird evolution by Luis Chiappe. This review mentions the first 85 million years of bird evolution; we know that there is far more to the bird evolution story than just 85 million years. The bird is also mentioned many times in Sankar Chatterjee's The Rise of Birds. Chatterjee mentions Protoavis multiple times, probably because he did the original description. However, he does mention it in relative situations and for good reason. Appropriate mention of your own described taxon is tasteful and worth appreciating.
