摘要	The maximum locomotor capabilities of theropod dinosaurs have long been a subject of considerable scholarly, primarily due to the lack of contemporary species for direct comparison. Biomechanical modeling and the analysis of dinosaur trackways have yielded significant theoretical insights into this area of research. This study investigates the running speed of a mid-sized theropod dinosaur trackway recently identified in the Otog region of Inner Mongolia, and it juxtaposes these findings with other running theropod trackways from diverse various global locations utilizing standardized inference methodologies. The results indicate that the trackmaker was capable of achieving a running speed of 45 or 41 +/- 4.9 km/h, thereby establishing it as the fastest-running theropod trackway documented from the Cretaceous period. Additionally, this paper reviews biomechanical investigations concerning the maximum running speeds of theropod dinosaurs and illustrates that the inferred speed of this mid-sized theropod aligns with the predictions of the majority of biomechanical models, thereby providing compelling new evidence to enhance our understanding of the locomotor capabilities of mid-sized theropods.
