  There are quite a few alligatorids with low and rounded, or simply downright
bulbous posterior teeth. Most alligatorids and crocodylids are opportunistic,
and this may reveal ancestral features in the diet, but not neccessarily
declare the _current_ dietary regime. Note that features may be exapted from an
originally specialized function as well as be derived _for_ that function.
