A type specimen (IVPP V 12330) for the species was designated, and the species was described both within the paper and by reference to the National Geographic article--a
horrible description by scientific standards, but a description nonetheless. Thus, in April 2000, Archaeoraptor ceased to be a nomen > nudum.

_Archaeoraptor_ may no longer be a _nomen nudum_, but is it necessarily a valid genus? What diagnostic characters does Storrs Olson provide for the caudal series IVPP V 12330 of _Archaeoraptor liaoningensis_? If the caudal vertebrae show no diagnostic characters below the level of Dromaeosauridae or Maniraptora, then _Archaeoraptor liaoningensis_ may be dismissed as a _nomen vanum_.
