Footprint Evidence of Late Triassic Ornithischians from Central Europe?

This footprint assemblage from the Upper Triassic of Central Europe purportedly contains evidence for Triassic ornithischian dinosaurs (cf. Anomoepus isp.). As stated by the author this would be remarkable and offer new information regarding the early evolution of this group. However, the evidence is not conclusive as the taxonomic ID of the tracks is not certain, but I'd love to hear from someone who is more familiar with archosaur tracks what they think of this ID and discovery.

Niedźwiedzki, G. 2011. A Late Triassic dinosaur−dominated ichnofauna from the Tomanová Formation of the Tatra Mountains, Central Europe. Acta Palaeontologica Polonica 56: 291–300. doi:10.4202/app.2010.0027
Abstract - Osteological fossils of dinosaurs are relatively rare in the Late Triassic and Early Jurassic. Thus, ichnofossils are a critical source of information on Late Triassic terrestrial vertebrate communities. The outcrops of the Tomanová Formation (?late Norian–Rhaetian) in the Tatra Mountains of Poland and Slovakia have yielded a diverse ichnofauna. Seven more or less distinct morphotypes of dinosaur tracks have been recognized and are discussed. Most tracks are partly eroded or deformed, but are preserved well enough to be assigned to a range of trackmakers, including early ornithischians, small and large theropods (coelophysoids and/or possibly early tetanurans), and probably basal sauropodomorphs (“prosauropods”) or first true sauropods.
