Two things, even with the "W4TP" caveat: "fauna" doesn't necessarily mean
"dinosaurian fauna", although I'd have to go back to the abstract to check
However, diversity in this context is almost certain "number of species",
which is currently higher in the Hell Creek than the Horseshoe Canyon.
Disparity, however, is probably higher in the Horseshoe Canyon for the
reasons you mention.
