  A better ornithischian would be the closely related *Edmontosaurus
annectens*, the recorded record holder and long-jawed animal in terms of
rank and file of tooth positions; *Anatotitan* is I beleive a close
second, and I may have them backwards, but I was aware that it was
*annectens* that was the toothier of the two; but hey, they are both
Lancian edmontosaurs. The most multi-toothed theropod is *Pelecanimimus
polydon* with over two-hundred crowns grouped in the rostral 1/3 of its
jaws (in *Edmontosaurus* it is in the middle 1/3). The most multi-toothed
sauropodomorphan is, I beleive, long-jawed *Plateosaurus* with about 40
teeth total. Most other plateosaurs are blunter- and shorter-snouted
relative to height at the preorbital position of the lachrymal.

  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.
