  Hypsie skull material is few and far between, *Leaellynasaura being
among the best preserved for it's "grade" known to date. The material of
*Orodromeus* underwent monographic study by Scheetz recently, and
*Thescelosaurus* has been extensively studied, but the authors of the *L.
amicagraphica* paper chose to make general comparisons rather than
specific species to species studies, given the paucity of small hypsie
skull studies at the time (and now!). The frontoparietals of the type
specimen are, unfortunately, rather unique to *L.* since *Thescelosaurus*
and *Hypsilophodon* have broader more triangular frontals and a short but
broad parietal, rather than the hourglass-shaped frontals and long
parietal of *L.*

  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.
