 For instance, a classic 1910 reconstruction by Oliver P. Hay depicts two "Diplodocus" with splayed lizard-like limbs on the banks of a river.Hay argued that "Diplodocus" had a sprawling, lizard-like gait with widely splayed legs, and was supported by Gustav Tornier.This hypothesis was contested by William Jacob Holland, who demonstrated that a sprawling "Diplodocus" would have needed a trench through which to pull its belly.
