Effects of articular cartilage and posture on forward velocity of slow running and fast running theropod dinosaurs.

T. rex posture (124°, knee; 147°, ankle), Struthio posture (109°, knee; 142°, ankle), and columnar (Col) posture. All values are ms−1. Limb length data were taken from Sereno and Arcucci [79] and Hutchinson [69].

霸王龙（T. rex）姿态（膝关节角度124°；踝关节角度147°）、鸵鸟（Struthio）姿态（膝关节角度109°；踝关节角度142°）以及柱状（Col）姿态。所有数值的单位均为米每秒（m·s⁻¹）。肢体长度数据取自塞雷诺与阿尔库奇[79]以及哈钦森[69]的研究。
