Other interesting findings:
_Lesothosaurus_, _Gongbusaurus_, and _Agilisaurus_ form a monophyletic
group, one node higher than _Pisanosaurus_ at the very base of the
Ornithischia. (I think the name Lesothosauridae is available for this

_Monoclonius_ and _Brachyceratops_ are both retained as valid genera (as
favored by Dodson, at least provisionally - and contra Sampson, whose
ontogenetic studies favored their identification as immature

That's the understatement of the year! But I don't see any white flags
flapping in the breeze.

I'm not sure how the two are connected. Are you proposing that
_Deinonychus_ needed big rocks or mountains in order to launch itself
against large prey? _Deinonychus_'s hindlimb abilities would be sufficient
for it to leap onto the back of (say) an adult _Tenontosaurus_.
