As I recall that talk, it made it pretty convincing case that
Dracrorex and Stygiomoloch are juveniles, but didn't lay out case that
what they're juveniles _of_ is Pachycephalosaurus.  So it's still
possible that the Dracrorex holotype is a juvenile Dracrorex.  And of
course, unlike the Triceratops study that this alluded to, we're
dealing with some very small sample sizes here.

I run Linux, where the default PDF viewer is a thing called xpdf.  It
lets me copy and paste from the abstracts volume with no problems.
(It's also about a hundred times faster to start up than Acrobat
reader.)
