Basal paraves and pterosaurs do not have a intramandibular joint.Dinosaurs do have a intramandibular joint.
The unusual intra-mandibular joint described above is found only in herrerasaurids and theropods among dinosaurs. Dinosaurian outgroups (pterosaurs, crurotarsal archosaurs) also lack an intra-mandibular joint.BASAL PARAVES
[Archaeopteryx] does not appear to have had an intramandibular jointhttp://en.wikipedia.org/wiki/Odontognathae
.....intramandibular articulation something that is actually absent in Archaeopteryx, but found in many of its theropod relatives.
It would not tax the imagination to engender a long list of obstacles for the now dominant model of a theropod origin of birds, including....the sliding lower jaw joint [sliding intramandibular joint] of theropods (absent in birds)
The traits uniting Theropoda seem to include:http://www.bio.fsu.edu/James/Ornithological%20Monographs%202009.pdf
An intramandibular joint between the dentary and post-dentary bones: this may have served as a shock absorber while feeding on live prey. (Herrerasaurs have a slightly different configuration of the intramandibular joint, and thus may be convergent.)
the analysis of Benton (2004) demonstrated that the only unequivocal synapomorphy diagnosing Theropoda is the presence of an intramandibular joint.http://palaeos.com/vertebrates/coelurosauria/oviraptorosauria.html
