Another thing that needs to be appreciated is the difference between
species-level lumping and supraspecific lumping (or splitting).  I've been
called "the Mad Lumper" by more than one croc worker, because I tend to
lump harshly at the species level (for, in my view, good reason); but I
also tend to be a "splitter" at what used to be the "generic" level, as
some modern generic names (Crocodylus, Alligator,etc.) were used very
inappropriately in the past.

Y'all can guess what this will mean for my views of tyrannosaur systematics.
