Interesting critter if all the material belongs to the same animal (and I can't see any reason right now why it wouldn't). The broadly expanded basisphenoid appears to be particularily autapomorphic. Taxonomically I'm going to put my bet on a fairly derived paracrocodylomorph, especially because the supratemporal fossa incises the posterior margin of the frontal; however, the presence of a postfrontal suggests it is not a crocodylomorph. I'll refrain from plugging this taxon into the Nesbitt (2011) matrix as the authors clearly state that the phylogenetic relationships are part of Grzegorz Niedźwiedzki's PhD project.
I do have a question regarding the specific name. If the specific name intends "from Wawel Hill" should the correct name be Smok wawelensis or maybe S. wawelhillensis? As I have stated before I don't think it is the best idea for new taxon names to be published online in accepted manuscript form because the authors may decide to change the name or modify it before final publication.

Abstract - We describe a new large predatory archosaur, Smok wawelski gen. et sp. nov., from the latest Triassic (latest Norian-early Rhaetian; approximately 205-200 Ma) of Lisowice (Lipie Śląskie clay-pit) in southern Poland. The length of the reconstructed skeleton is 5-6 m and that of the skull 50-60 cm, making S. wawelski larger than any other known predatory archosaur from the Late Triassic and Early Jurassic of central Europe (including theropod dinosaurs and rauisuchian crurotarsans). The holotype braincase is associated with skull, pelvic and isolated limb-bones found in close proximity (within 30 m), and we regard them as belonging to the same individual. Large, apparently tridactyl tracks that occur in the same rock unit may have been left by animals of the same species. The highly autapomorphic braincase shows large attachment areas for hypertrophied protractor pterygoideus muscles on the lateral surface and a wide, funnel-like region between the basal tubera and basipterygoid processes on the ventral surface. The skeleton (cranial and postcranial) possesses some features similar to those in theropod dinosaurs and others to those in large crocodile-line archosaurs (rauisuchians), rendering phylogenetic placement of S. wawelski difficult at this time.
