The fossil material, particularly the nearly-complete skull, closely resembles bones of the contemporary related Parapsittacopes.[1]
A preliminary description of the fossil material was published by German paleontologist Gerald Mayr and Michael Daniels in 1998. In 2022, Gerald Mayr and British zoologist Andrew C. KitchenerdescribedPsittacomimus eos, a new genus and species of psittacopedid, based on these fossil remains. The generic name, "Psittacomimus", combines the Greek word "μῖμος" ("mimos"), meaning "imitator", with the name of the extant parrot Psittacus, in reference to the similarity of Psittacomimus with psittaciforms. The specific name, "eos", references the discovery of the fossils in Eocene-aged sediments. Additional bones discovered at the same locality were also assigned to Psittacomimus as referred specimens.[1]
