Indeed. The general consensus among some the heavy hitters that I have spoken
with or had hear second hand (i.e. by Kranz) is that this _single_ tooth is
quite unique both locally among the Arundel  remains but  is also unique
among contemporaneous remains (Aptian) elsewhere in the US but I hesitate to
say the "world".

That's good to hear for I believe that at least in the case of the Arundel
fauna, the overwhelming majority of remains collected thus far are
indeterminate, that the prospect of applying this method to other specimens
must now be given deep thought. I have now a good collection of theropod
teeth that are in the same boat taxionomically. Those that have looked at
them (some) have said that these too are unique. It has started me thinkng...
