It´s likely they could perch on two legs. However, looking at their short, webbed, hind legs, it´s likely they had a hard time bouncing around like birds do. Besides, looking at gliding reptiles today, it´s most likely that pterodactyls evolved from four legged reptiles similar to lizards, which suggests that they must have felt more comfortable walking on their four legs instead of two.
No, theropods, as a group, are bipedal. Some believe spinosaurs could of been occasional quadrupeds, though, but its unlikely.
No. all carnivorous dinosaurs walked on two legs.
Yes. All dinosaurs were two legged to run fast and catch prey.
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 that walk on two legs are called "bipeds". The term applies to all animals that walk on two legs.
Theropods were the main bipedal dinosaurs. However, some small ornithopods, like Orodromeus, were bipeds, and hadrosaurs could walk on two or four legs.
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.
Triceratops are very large dinosaurs that had trouble lifting their body weight. Because of natural selection the dinosaur adapted to walking on four of it's legs instead of two.
No, it possessed two massive legs and two small arms.
Animals walk on four legs because it is more stable than walking on two legs. Dinosaurs were very large, and it would have taken a lot of energy for them to walk on two legs. The ones who did walk on two legs were usually predators (like Tyrannosaurus rex or velociraptor) because they could get more energy from eating other animals than from eating plants.
Any animal that walks on four legs is called quadrupedal. Quadrupedal dinosaurs include sauropods, stegosaurs, ceratopsians, and ankylosaurs. Hadrosaurs could were usually quadrupedal, but could walk, stand, or run on two legs.
the dinosaurs walk slowly b/c they would get raped by the cave men at night, their asses would be red and sore, that's how they got their dino"saur"
Tortoises have four legs that they walk with.
four legs
