I last heard it had a large number of similarites to Dryptosaurus.  Is

Bahariyasaurus?  Is it a noasurid too or is it closer to Dryptosaurus or
Tyrannosaurs.  I saw a drawing of what was supposed to be the pelvis of
Bahariyasaurus and it looked to be very similar to the pelvises of
Tyrannosaurs, but I could be mistaken.>

  From what I have heard based on Longrich's study, and this is only
observational, *Deltadromeus*, as in other noasaurids and "elaphrosaurs"
(aka, basal Abelisauria, Abelisauroidea) has lateral and medial
metatarsals narrower than the central, third metatarsal. The
scapulocoracoid is also reminiscent of *Carnotaurus*, but its the pes, I
think that is the strongest data appealing to not only a abelisaurian
relationship, but affinities to the noasaurids (including the
velocisaurids).

  Little steps are often the hardest to take.  We are too used to making leaps 
in the face of adversity, that a simple skip is so hard to do.  We should all 
learn to walk soft, walk small, see the world around us rather than zoom by it.
