Tom Holtz suggested a close relationship with _Dryptosaurus_ (Cope's
_Laelaps_) from the Maastrichtian of New Jersey. I'm quite inclined to
agree with him because of the general proportions of the hind limbs of
_Deltadromeus_ and _Dryptosaurus_, but to clinch it I'd like to see a
picture of a _Dryptosaurus_ metatarsal III: if it's >>not<< pinched,
we've got a good case for referring _Deltadromeus_ to Dryptosauridae.
