In 2002 the Czerkases published a volume through their Dinosaur Museum titled ''Feathered Dinosaurs and the Origin of Flight''. In this journal, they described and named several species.<ref name="Czerkas">{{cite web| last = Czerkas| first = Stephen A.| title = Feathered Dinosaurs and the Origin of Flight| publisher = The Dinosaur Museum| year = 2002| url = http://www.dinosaur-museum.org/featheredinosaurs/chapters.htm| access-date = 2008-06-13| archive-url= https://web.archive.org/web/20080617200533/http://www.dinosaur-museum.org/featheredinosaurs/chapters.htm| archive-date= 17 June 2008 | url-status= live}}</ref> Of the six species named in the book, five are disputed.

Despite the work of Zhou ''et al.'' (2002), Czerkas and co-author [[Xu Xing (paleontologist)|Xu Xing]] described the upper portion of the "Archaeoraptor" fossil as a new bird genus, ''[[Archaeovolans]]'', in the ''Dinosaur Museum Journal''. The article does include the caveat that it might be a specimen of ''Yanornis''.<ref name="Czerkas2002">Czerkas, Sylvia J. ed. (2002) "Feathered Dinosaurs and the Origin of Flight" ''The Dinosaur Museum Journal'' Volume 1. Blanding, Utah, USA. The Dinosaur Museum, August 1, 2002</ref> Thus, this same fossil specimen has been named "Archaeoraptor", ''Archeovolans'', and ''Yanornis'' in different places.

Across the monographs in the ''Dinosaur Museum Journal'', Stephen Czerkas built a case for his controversial view that maniraptoran dinosaurs are secondarily flightless birds. In so doing, he criticized prominent paleontologists. In the text on ''[[Cryptovolans]]'', Czerkas accused Dr. [[Mark Norell]] of misinterpreting the fossil BPM 1 3-13 as having long leg feathers due to the "blinding influences of preconceived ideas."<ref name="Czerkas2002"/> Though Norell's interpretation was correct, Czerkas added leg feathers to his reconstruction of the fossil in the art that promotes the traveling exhibit.<ref>{{cite web|url=http://www.fresnomet.org/exhibition/feathered_dinosaurs|title=Feathered Dinosaurs and the Origin of Flight – Fall 2008 to March 1, 2009|access-date=2008-06-14|publisher=[[Fresno Metropolitan Museum of Art and Science]]|archive-url=https://web.archive.org/web/20080511065332/http://www.fresnomet.org/exhibition/feathered_dinosaurs|archive-date=11 May 2008|url-status=dead}}</ref>

Two other taxa that Czerkas and his co-authors named were later treated as junior synonyms by other authors. Czerkas' ''Cryptovolans'' was treated as ''Microraptor'',<ref name="Feducciaetal2005">{{Cite journal | doi = 10.1002/jmor.10382 | last1 = Feduccia | first1 = Alan | author-link = Alan Feduccia | last2 = Lingham-Soliar | first2 = Theagarten | last3 = Hinchliffe | first3 = J.

Another taxon that Czerkas assigned to the [[Pterosauria]] and named ''[[Utahdactylus]]'' was reviewed by Dr. Chris Bennett. Bennett found multiple misidentifications of bones and inconsistencies between Czerkas' diagrams and the actual fossils. Bennett found the specimen to be an indeterminate diapsid and criticized the previous authors for publishing a species name when no diagnostic characters below the class level could be verified. He made ''Utahdactylus'' a ''[[nomen dubium]]''.<ref name="Bennett2007">Bennett, S.
