Bipedal Animals

Bipedal group has evolved a number of times other than in humans, mostly among the vertebrates. The most obvious example of bipedal Movement is among the birds and their ancestors the theropod dinosaurs. All dinosaurs are supposed to be descended from a fully bipedal Ancestor, perhaps similar to Eoraptor. Indeed, among their descendants, the larger flightless birds, the ratites, such as the ostrich, perhaps .
Epitomize the capacity to move bipedally, able to reach speeds of up to 65 km/h. likewise many theropod dinosaurs, especially the maniraptors, are supposed to have been able to move at similar speeds. Bipedal movement also re-evolved in a number of other dinosaur lineages such as the iguanodons. Bipealism has also evolved in the crocodilian line, a sister group to the dinosaurs and birds - a crocodile relative from the Triassic, Effigia okeeffeae, was believed to be bipedal. Penguins are attractive birds with regard to bipedality as they tend to hold their bodies upright, rather than horizontal as in other birds.
