I agree,the known material does look a bit more derived than Dilophosaurus.
Very nicely done

Awesome! I love those late Trriassic and early Jurassic theropods

I think that Shuangbaisaurus, as you put it, is more derived than Dilophosaurus and Sinosaurus; but I would go further as to say it illuminates more of the cranial anatomy of the mysterious basal tetanurans such as Dandakosaurus theropoddatabase.com/Megalosau⦠and Saltriosaurus theropoddatabase.com/Tetanurae⦠. Good work by the way, it is very interesting.

Yeah, that seems really reasonable.π

I love the Early Jurassic Dinosaurs, and another addition to the Dilophosauriade-Tetanureae Tree is welcome

I very much agree, anything basal is definitely accepted here.

Could Shuangbaisaurus be reconstructed like Liliensternus - in the sense that there is no material implying a crest, but it has been reconstruction both with, and without a crest.

Yes a crest is definitely possible, although it was probably low if there was one.

Now that I see the skull, it doesn't look like it's a member of dilophosaurid-grade theropods.

I do agree. Just remember, the grey material is all guesses

True, I guess we need a more thorough analysis on this before its cladistic relationships are concluded.

Definitely. Sadly the paper only gives 2 views of the skull and not much else except basic descriptions and comparisons.
