Dinofact #102
Tawa hallae possesses attributes that can be assosciated with different dinosaur taxa. For example, its skull morphology resembles that of coelophysoids, and its ilium approximates that of a herrerasaurid. It also possesses an adaption in its neck vertebrae which supports the idea that cervical air sacs predate Netheropoda and may be ancestral in Saurischians.
