Body mass, bone “strength indicator,” and cursorial potential ofTyrannosaurus rex

摘要: ABSTRACT We describe a new life restoration of Tyrannosaurus rex, based on fairly complete skeleton (Museum the Rockies [MOR] 555). From volume this model, we estimate live mass full-sized dinosaur as approximately 6,000 kg. Because MOR 555 is representative gracile morph T. robust may have been substantially greater. The “indicator athletic ability” or “strength indicator” 7.5–9.0 meter2/giganewton, similar to previously reported results. implication that cursorial potential was limited, conclusion consistent with observed declines in sprint speed increasing body living animals, and also tibia/femur length ratio, construction hip joint, dinosaur. Furthermore, mathematical models impact forces decelerations would affect Tyrannosaurus, were it fall while running at high (20 meters/second), suggest animal wou...
