Critique
Paul (2002:26) coined Avepectora as a form-qualified stem-based definitions based on “the majority of the distal edge of strongly anteriorly facing coracoids articulates with the anterior edge of a broad sternum at an angle of approximately 45-90 degrees from the midline.” Interpretation of this apomorphy, of course, is problematic in that it is preserved in few taxa. In ornithomimids, which Paul (2002:24) includes as a basal member of the clade, only one basal taxon has an ossified sternum, but the coracoids are not preserved in place and it is not at all clear how much of the coracoid would have been in contact with the sternum. The sternum is unknown in therizinosauroids, another basal member of the clade according to Paul (2002:24).

All averostrans in which the majority of the distal edge of strongly anteriorly facing coracoids articulates with the anterior edge of a broad sternum at an angle of approximately 45-90 degrees from the midline, or that descended from such avepods, and are members of the clade that includes Dromaeosauridae.
