It had the longest neck it as at about 85 feet in length which is a lot longer than a giraffes neck. It wasn't very deadly as other dinosaurs. A health adult brachiosaurs had no predators due to its massive looking body. The only major predators were allosaurs packs which hunted brachiosaurs young. It weighted in at about 56 metric tons. It was just a friendly animal but was threatened by other carnivores it would react negatively.
The stegosaurs dinosaur was plant eater. The stegosaurs has spines on its back that helps it defend its self from predators. It had a big body but its head wasn't as big as other animals. The main predator it had was the t-rex and the allosaurs. It wasn't fast it only could reach speeds of 4.3 miles per hour which was pretty slow among the dinosaurs kingdom. Stegosaurus had a small, flat head and a turtle-like beak. It walked on four legs, and had hoof-like toes. A grown stegosaurs dinosaur could have weighted at about 6,800 pounds. Even though they weren't meat eaters the were deadly due to there spines.
The allosaurs was the earliest dinosaur discovery. The allosaurs was also a carnivore which is a meat eater. The name Allosaurus means 'different lizard'. Allosaurus had a large skull and walked on two legs. Its body and head were balanced by a long and heavy tail. Allosaurs were scavengers and hunters. Many Allosaurs hunted in packs because it made it a lot easier. An allosaurs had a weaker bit that most dinosaurs at its time. An allosaurs wasn't really fast scientist have said that it could maybe reach the speeds of 21 miles per hour. Allosaur weren't the most powerful dinosaurs but the weren't really scared of anything except the t-rex.
The t-rex was carnivore which means it was a meat eating animal. The t-rex wasn't the biggest animal but it was the biggest meat eating animal.
