<Does anyone know the basis for Deltadromeus being a noasaurid? From what I last heard it had a large number of similarites to Dryptosaurus. Is there any possibility that it could be chimerical? What about 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.
