"These growth stages reflect a growth continuum rather than specific developmental steps defined by “known” terminal morphologies. This is important because currently we do not know the ultimate size or maximum age of any dinosaur species and an adult growth stage assignment purports a potentially false terminal morphological state."

Then Horner proceeds in the table to assign Pachycephalosaurus as an "adult" and the other two genera as juveniles and subadults of it.

We've also got a ome that currently can't be assigned to anything, this would be fine for the hypothesis, except that it had the fused skull, and this sinks into my last part of the argument, the "sub adult" specimen doesn't.

Finally, the younger juvenile is the same size as the sub adult, um, would you like to explain.
