Tracks of large theropods and a single sauropod footprint are reported
from red beds at Beikeshan locality in the Middle Jurassic Chuanjie
Formation, of Lufeng County, near the large World Dinosaur Valley Park
complex. The Chuanjie theropod tracks are assigned to the ichnogenus
Eubrontes and the large sauropod track is given the provisional label
Brontopodus. All occur as isolated tracks, i.e., trackways are not
preserved. Saurischian dominated ichnofaunas are relatively common in
the Jurassic of China. The producers of the Chuanjie tracks may have
been similar to the basal tetanuran theropod Shidaisaurus and to
mamenchisaurid sauropods, which were widely distributed throughout
China, during the Jurassic, and are known from skeletal remains found
in the same unit. Other potential sauropod trackmakers include
titanosauriforms or as-yet-unknown basal eusauropods. The ichno- and
skeletal records from the Jurassic of the Lufeng Basin are largely
consistent, and both document the presence of middle-large sized
theropods and sauropods.
