Is Dandakosaurus a basal abelisauroid

I was just wondering if Dandakosaurus a Jurassic theropod from the Central Indian formation could have relevance to the origin of the Abelisaurs. The D- shaped teeth are quite reminiscent of Majungasaurus and Indosuchus.

The maxilla like the abelisaurids lacks an extensive lateral antorbital fossae. The antorbital cavity has an anteroventral foramen with an internal connection which is also reminiscent of the similar structures of Indosuchus and Abelisaurus.

It is possible that Dandakosaurus was ancestral to the Cretaceous abelisauroids.

Has any one compared in detail Velocisaurus of Bonaparte with Noasaurus.

Do they seem to form a natural group. If yes what characters seem to support this.
