A new paper:
At the Middle Jurassic Wenda tracksite, in eastern Tibet, at least eight surfaces bearing dinosaur footprints are exposed. One of them, the WD6 track-bearing surface, shows the highest density of tracks, with forty-eight tridactyl tracks. They are assigned to Eubrontes isp., Wildeichnus isp. and indeterminate theropod tracks (including Morphotype 1 and Morphotype 2). The newly reported large carnivorous dinosaur track, Eubrontes isp., represents one of the best preserved theropod ichnotaxon found in Tibet, and its morphology is characterized by clear digit pads and blunt claw imprints. Wildeichnus isp. is a common small theropod footprint of the Wenda tracksite, which is less than 8 cm long and smaller than the Theropod Indeterminate Morphotype 2. Although Theropod Indeterminate Morphotype 1 shows some features of Anchisauripus, this study do not consider a distinct attribution at the ichnogenus or ichnospecies-level, because the key taxonomical characters of the digits are missing. The current study suggests that the Middle Jurassic theropod ichnoassemblage of eastern Tibet can be assigned to a Eubrontes-Grallator plexus. The ichnoassemblage of eastern Tibet are somewhat similar with the adjoining areas, and the eastern Tibet was inhabited by abundant dinosaurs, during the Middle Jurassic.
