Analysis of the acceleration phase of a theropod dinosaur
Analysis of the acceleration phase of a theropod dinosaur based on a Cretaceous
trackway from Korea
]Well-preserved trackways of carnivorous dinosaurs belonging to small-sized theropods have been reported
from the Cretaceous Neungju Group in South Korea. The site at Hwasun Seoyu-ri Quarry represents the most
extensive and diverse theropod trackway ichnofauna in South Korea. Among them, one theropod trackway is
unique in that it demonstrates that theropods were able to increase stride lengths to reach maximum speed,
during the running phase. Fossilized track evidence of the acceleration ability of dinosaurs is scant. Despite
this, the evidence shown in our findings suggests a theropod running near the limit of its capabilities and
shows evidence of a temporary acceleration of speed while running.
