True Dryptosaurus is a Late K theropod from the New Egypt Formation of NJ
and equivalents.  Gilmore referred some of the Arundel theropods to
Dryptosaurus, and then to Allosaurus.  I don't think any evidence is
convincing for either.

There is a paper on Dryptosaurus by various authors in press in JVP.

There really isn't very much.  I'll try and find what I can.

I look forward to it.
