Theropod tracks, Eubrontes, Ichnofaunas


A single well-preserved theropod trackway identified as Eubrontes was discovered in the Lower Cretaceous (Berriasian-Valanginian) Cangxi Formation on the northern margin of the Sichuan Basin This is the first report of tracks from this formation. The occurrence is consistent with reports of theropod dominated ichnofaunas from broadly coeval deposits such as the Feitianshan Formation in southern parts of the basin. There is growing evidence that Eubrontes and Eubrontes-like tracks are common in the Lower Cretaceous of Sichuan Province.
