  While large head and eyes seem to occur typically among rather small
birds and mammals today, relative to their trunk length say, or large eyes
indicative of a possible nocturnal habit despite apparent fusion of some
braincase elements in *Scansoriopteryx,* there are also what appear to be
poorly-defined margins between bones that indicate incomplete limb growth.
These animals may be younger than subadults, and could be only about 1/3
or less adult size (but that's pushing predictive ability fairly far).

  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.
