Or maybe a coelophysid...
There is very little chance Lukousaurus is coelophysoid, even if it turns out to be dinosaurian. The main reason is the absence of a subnarial gap, but I suppose the coelophysoid Shuvosaurus also lacks this. Using Rauhut's thesis, it also lacks the coelophysoid characters of a horizontal maxillary ridge and a squared anterior margin of the antorbital fossa. I think I'll look over Lukousaurus again soon and see if I can improve upon its previous phylogenetic placement.
