Among diprotodonts, the family Macropodidae includes both bipedal (e.g., kangaroos and wallabies) and quadrupedal (tree kangaroos) taxa. To define humans categorically as “bipedal” is not enough; to describe them as habitually bipedal is nearer the truth, but habit as such does not leave its mark on fossil bones.

Segment and joint angles of hind limb during bipedal and quadrupedal walking of the bonobo (Pan paniscus). The problem arrives that it is often very difficult to associate trace fossils with a particular organism. Results: Quadrupedal rats assumed an upright posture for a significantly greater amount of time than bipedal rats when monitored over 24 hours (P = 0.016).

Bipedal and quadrupedal walking among chimpanzees was similar to that reported for bonobos, gibbons, and other primates. This of course also makes them quadrupedal, or "pentapedal" (meaning "five-footed") if you want to count the tail, because in fact their tail does act as a leg.

According to the Discover Wildlife magazine, male gorillas weigh between 325 pounds and 373 pounds and can grow up to 5.9 feet tall. One of the proposed mechanisms was the knuckle-walking hypothesis, which states that human ancestors used quadrupedal locomotion on the savanna, as evidenced by morphological characteristics found in Australopithecus anamensis and Australopithecus afarensis forelimbs, and that it is less parsimonious to assume that knuckle walking developed twice in genera Pan and Gorilla instead of … This is exactly what evolution ultimately ends up doing. Kangaroos, primates, wallabies, and even certain lizards like the basilisk can travel using both means. Locomotion and posture from the common hominoid ancestor to fully modern hominins, with special reference to the last common panin/hominin ancestor. Quadrupedalism is a form of terrestrial locomotion where a tetrapod animal uses all four limbs to weightbear, walk and run.An animal or machine that usually maintains a four-legged posture and moves using all four limbs are said to be a quadruped (from Latin quattuor for "four", and pes for "foot").

Hope you all enjoy! This reconstruction was way different than the original one and from that moment it started to think that Spinosaurus was not bipedal, but quadrupedal , also it has been proven that Spinosaurus was not a dinosaur hunter, but a fish eater which spent most of the time in water as a crocodile. Gorillas: Gorillas are a type of great ape found in the forested mountains of Africa. Knuckle walkers do so because their wrist bones have different features from bipeds. Notable differences include hip and trunk angles, which reflected a more orthograde trunk posture during bipedalism, and mediolateral ground reaction forces, which were larger during bipedal walking.
