Altirhinus

Banding
As its forelimbs were roughly half the length of its hindlimbs, Altirhinus appears to have been primarily bipedal. However, its wrist bones were thick and blocky, and the three middle fingers of its hand were wide, hyperextendable, and ended in hoof-like bones. This indicates that the forelimbs were capable of supporting weight. Like many ornithopods, Altirhinus may have spent a significant amount of time in a quadrupedal position.
