摘要
The authors of this paper make a comparison between the footprints found in the two track sites in footprint size, shape and pace angulations etc. The authors made more than 10 plaster casts in both track sites. Based on these casts and the field records, the authors calculated the hip height and locomotion speed of the track-makers according to conventional calculation methods. The gait of the track-makers is also postulated. The authors think that it is reasonable to compare Chirotherium with dinosaurs. The authors hope that further study of Chirotherium may help understand the origin and extinction of dinosaurs.
