synonym of Pelorosaurus.>

  This is a quandary, eh? "Panoplosaurus," the sauropod stem, versus the
taxon *Panoplosaurus,* it's pan-stem is "Panpanoplosaurus," and ... I
notice a _weensy_ small problem here. Also noted: Pancrustacea exists, but
it's the crustacean/insect "pan-stem," NOT the crustacean one. Gah, this
only enforces my dislike of pan-stems.

  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.
