Re: New troodontid in PLoS ONE

The reporter seems to have gotten a little confused... From the paper:
"Troodontid possessing a maxilla with extensive pneumatization
internal to the antorbital fossa, inflating the bone so that it has a
triangular cross-section;"

That is, the bone is inflated by a static pneumatic cavity. It was not
inflatable like a balloon.
