| 11. | Most birds are digitigrade animals, which means that they walk on their toes, not the entire foot.
|
| 12. | The metacarpals of neosauropods are bound together, allowing a digitigrade posture with the manus raised up off the ground.
|
| 13. | Kangaroos look quite digitigrade when they are at speed . talk ) 03 : 34, 4 May 2008 ( UTC)

| 14. | This is different from later barbourofelids, which are believed to have had semi-plantigrade or semi-digitigrade stances.
|
| 15. | Many mammals, such as cats and dogs are digitigrade, walking on their toes, the greater stride length allowing more speed.
|
| 16. | They also developed a digitigrade posture in the hindlimbs, in which the heel and proximal metatarsals were raised completely off the ground.
|
| 17. | Early mesonychids probably walked on the flats of their feet ( plantigrade ), while later ones walked on their toes ( digitigrade ).
|
| 18. | However, birds actually have forward-facing knees; they are digitigrade, and what most call the " knee " is actually the ankle.
|
| 19. | It commonly grows high on the leg such that in digitigrade species, when the animal is standing, it does not make contact with the ground.
|
| 20. | AFAIK, all birds that can walk can walk backwards, while they are digitigrade, there's no physiological reason why they can't.
