Possible pseudosuchians are represented by quadrupedal
trackways very similar to Brachychirotherium parvum (Hitchcock 1889; Baird 1957; Haubold 1971) (Fig.
2010) also pointed out that the hindlimb mechanics of vertical climbing and quadrupedal
knuckle-walking are rather similar, involving highly flexed postures of the hip and knee, and suggested that it is in fact these locomotor behaviours that are likely to be functionally and ecologically linked.
She said that bipedal jerboas and quadrupedal
jirds share the same habitat, predators, food source, and active hours and it appears that their different forms of locomotion create differing predator evasion abilities, allowing jerboas to forage further from their burrows, thus limiting interspecific competition.
Mina joins a growing list of technologies and innovations developed by the IHMC robotics team including humanoid robots that can walk and balance while being pushed, reconfigurable dynamically balancing robots, and algorithms for quadrupedal
robots that can walk over very rough terrain.
The first section reviews general osteology, describing major features of bone and growth and development, and comparing quadrupedal
mammals to human bones.

They stay in shape by doing push-ups, sprint drills and quadrupedal
movements on all fours.
R]e-EN It[R]e-es the first time we try to construct a quadrupedal
small mammals, joints are immobilized in a neutral standing angle to optimize limb function and to minimize adverse effects on ipsilateral and contralateral joints.
