t;EnDivSummary">In this paper, the authors describe seven non-avian theropod trackways from the Baoyuan track site in the mid-Cretaceous Wotoushan Formation (Jiaguan Formation) in the Chishui area, Guizhou Province, China. Preliminary palynological analysis indicates Late Cretaceous age not earlier than Cenomanian at the oldest. Footprints at the site pertain to cf. Irenesauripusi sp. Most tracks preserve partial metatarsal pads that are not distinct from their respective meta-tarsophalangeal regions. Several elongate digit impressions may indicate that digit II of the track maker possessed a long claw, longer than on any of the other digits.Most notably, the Wotoushan (Jiaguan) fauna lacks sauropods andis dominated instead by theropods and ornithopods.
