Wealden-inhabitant, Ornithodesmus, which was originally described as a
pterosaur, but has since been identified as a theropod. If other theropod
material in the Wealden named and described after Ornithodesmus could be
classified as being a synonym of Ornithodesmus, it would be renamed as
such.>

  Correct me if I am wrong, but Seeley originally described *Ornithodesmus
cluniculus* as a bird; it was the discovery of pterosaur bones and the
now-named *Istiodactylus latidens* (formerly *O. latidens*) that prompted
referral to the pterosaurs. Roughly translated, it means "related [or
linked] to birds." Current thought would have it as a troodontid, or
dromaeosaurid, or some generic maniraptoran.

  Little steps are often the hardest to take.  We are too used to making leaps 
in the face of adversity, that a simple skip is so hard to do.  We should all 
learn to walk soft, walk small, see the world around us rather than zoom by it.
