September 30, 2016:
The Nianpanshan dinosaur tracksite, first studied in the 1980s, was designated as the type locality of the monospecific ichnogenus Jinlijingpus, and the source of another tridactyl track, Chuanchengpus, both presumably of theropod affinity. After the site was mapped in 2001, these two ichnotaxa were considered synonyms of Eubrontes and Anomoepus, respectively, the latter designation being the first identification of this ichnogenus in China. The assemblage indicates a typical Jurassic ichnofauna. The present study reinvestigates the site in the light of the purported new ichnospecies Chuanchengpus shenglingensis that was introduced in 2012. After reevaluation of the morphological and extramorphological features, C. shenglingensis is considered here as a nomen dubium. The present study also provides details of tail traces associated with two of the Anomoepus trackways and adds additional detail to the 2001 tracksite map.
