Wild guesses:  Perhaps the different shaped teeth came from different
parts of a juvie's jaw?  Or tooth shape changes (becomes more robust) as
juvies age?

BTW:  If Jane has bladed teeth, then that may remove one of the purported
undescribed "large dromaeosaurids" from the Hell Creek fauna (currently
known only from shed teeth)..

As is custom here, the acronym WFTFP applies. (the 2nd "F" added for
dramatic effect).
