Theropods were the main bipedal dinosaurs. However, some small ornithopods, like Orodromeus, were bipeds, and hadrosaurs could walk on two or four legs.
An animal that walks on two legs is called a biped. Examples include birds, kangaroos, and some dinosaurs.
Biped
Birds are mainly just a modern, evolved therosaurus dinosaur. Most likely, the dinosaurs were not reptiles like lizards are.
The Biped stood there silently.
the biped ran as fast as he could

The ancestral mode of locomotion of dinosaurs is thought to be bipedalism. This is supported by the fossil finds of early, basal dinosaurs such as Eoraptor, which lived during the Middle Triassic, over 230 million years ago, and which are clearly bipedal. In fact, bipedalism evolved in the archosaurian ancestors of dinosaurs, and dinosaurs simply inherited it, as did their close relatives. Later on, some dinosaurs evolved quadrupedalism, and this happened independently in several lineages of dinosaurs, such as the ceratopsians (i.e. Triceratops) and sauropods (i.e. Apatosaurus). Some were mostly quadrupedal, but could occasionally assume a bipedal posture (it is believed that hadrosaurids were facultatively bipedal while running, for example). Finally, some retained their ancestral bipedalism - this includes the theropods, and their modern descendants, the birds.
I am a biped. A biped is an organism that walks on two feet.
No it is not. A biped is a creature with two feet and a frog or toad has four feet.
A biped organism has 2 feet like a gorilla or ape! It is a mammal.
bi = two ped = having a foot biped has two feet
A biped walks on two limbs and a quadruped walks on four.
