  What could be cerebral hemispheres are small. I also suggested that
these may be part of the dorsal cranial sinus system, part of a dorsally
pneumatic braincase as in maniraptorans. This is merely plausible, and
suggests perhaps a brain cooling function in analogy to that of some birds
with trabecular dorsal frontals. As for the olfactory bulbs, typically
there is a trend to reduced them with increased eyes, inversely for
increased sense of smell. Absence of tiny bulla for proposed endocranial
width does not rule out maniraptoran affinity.

  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.
