All dinosaurs had four limbs. Some dinosaurs, like Tyrannosaurus and Allosaurus, were bipeds, which means that they only walked using their two hind limbs. Other dinosaurs, like Stegosaurus, Ankylosaurus, and Diplodocus, always walked on all four limbs, making them quadrupeds. And some dinosaurs walked on all fours, but ran on their two hind legs. Examples of such dinosaurs include Igaunodon and Parasaurolophus.
The Oldest Dinosaur fossil ever found was a omniraptor, and it walked on two legs.
Dinosaurs that walk on two legs are called "bipeds". The term applies to all animals that walk on two legs.
Mos species of dinosaur walked on 4 legs, but some, including all carnivorous dinosaurs, walked on 2 legs.
No, not all carnivorous dinosaurs walked on two legs. Some carnivorous dinosaurs, like the theropods, were bipedal, walking on two legs. However, others, such as the ceratosaurs, were quadrupedal, walking on four legs.
You mean DID - triceratops are extinct. They were four-legged dinosaurs, however.
No carnivorous dinosaurs walked on four legs. Some famous carnivorous reptiles that predate dinosaurs are often mistakenly called dinosaurs. An example is the Dimetrodon.
dinosaurs shared many features with todays lizards. they had skeletons with backbones. they had scales. many walked on four legs. but there differences between the two groups of animals. dinosaurs legs go almost straight down from their bodies. legs of todays lizards stick out more from the sides of the bodies. some dinosaurs share many features with birds. for instance, some dinosaurs had features and a wishbone! also, a few fossils have included more than just bones. these fossils have shown that some dinosaurs had a heart that is similar to a birds or a mammals heart. NOTE: ( i got this info from my science book )
are dinosaurs faster in 2 or 4 legs
No, there were in fact quite a few herbivores that ran on two legs, like microceratops and leaellynasaura. There are no two-legged carnivores though because the first carnivore was Coelophysus, a two-legged carnivore and all the carnivores evolved from that point.
Yes There were only a few of them around
Dinosaurs were a subset of reptiles but they were different from any modern reptile. Modern reptiles are cold-blooded animals with a fairly slow metabolism. They walk with their legs stuck out to the side except for snakes and some lizards which have no legs. They are covered in scales. By contrast dinosaurs walked with their legs erect directly beneath them. There is evidence that many dinosaurs were warm blooded and had active lifestyles. Some are now known to have been covered in feathers rather than scales. A number of dinosaurs such as velociraptor were much more like birds than like modern reptiles.
No. Actually, the elephant is the only animal with four knees.
