چکیده انگلیسی
The well-preserved theropod track Weiyuanpus zigongensis, recently assigned to Eubrontes zigongensis, was not described in exhaustive detail at the time of its original discovery in 2007. Among the morphological details not described was an antero-medially directed hallux seen in five of the six tracks that make up the type trackway. Hallux traces are only rarely reported in large Lower Jurassic theropod tracks such as Eubrontes and Gigandipus, and their presence or absence may be the result of one or both of two factors: track depth and/or differences in hallux configuration in the trackmakers. Here we argue that E. zigongensis is one of the best preserved examples of a eubrontid track, which can be morphologically distinguished from other Eubrontes ichnospecies by the presence of well-defined hallux traces.
