In recent years the number of track sites discovered and reported from the Lower Cretaceous Jiaguan Formation, Sichuan Basin has increased steadily. Here we report on the 20th and 21st sites which are situated in unusual locations in a cave and on a steep bedding plane surface in association with Tang Dynasty grottoes. The ichnofauna is represented by two small assemblages which are both theropod-dominated. Due to sub-optimal preservation, the tracks are identified only as grallatorid and small and larger eubrontid, with Paracorpulentapus also tentatively recognized.
