      HYMV1-1: Partial articulated skeleton w/ skull material, missing
only forelimbs and distal caudal vertebrae
      Hypodigm APK:25/75: HYMV1-2 furcula, partial right shoulder girdle
and forelimb; HYMV1-3 partial right manus, and HYMV1-4, both associated
with holotype skeleton; and MYMV1-5, left manus; all in addition to
holotype skeleton and likely belonging to the same individual.>

  As a clarification, there are at least two specimens of *Heyuannia*
preserved on the block described by Lü. See:


  where in one sentence I wrote: The holotype and four refered specimens
are HYMV1-1--5, and are all essentially on the same block and all probably
even belong to the same specimen." This was an allusion to a simgle
specimen being, not an individual, but block of fossils. Later, I write:
"Two animals are preserved together, possibly three: the first animal is
represented by the type; another is represented by partial legs and pubis
(HYMV1-4) that are closely assosicated to the type, in that they form a
contiguous block when assembled; HYMV1-3 and 1-5 are both separated and
represent a right manus and right arm, respectively. The manus may belong
to the type, as it lacks forelimb material, but the right arm has a
furcula, as does the type, and it does not belong to the same animal." 

  I hope this helps.

  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.
