Allosaurus was 28 to 32 feet long and weighed somewhere between 2,200 and 8,800 lb depending on whose estimate you use. Tyrannosaurus rex was 40 feet long and weighed 12,000 to 26,000 lb. Tyrannosaurus rex would almost definitely defeat and kill an Allosaurus in a fight unless the Allosaurus managed to escape. Note that they never would have encountered each other, though, because Allosaurus died out about 97 million years before Tyrannosaurus evolved.
Albertosaurus lived between 71 and 68 million years ago. Stegosaurus lived between 155 and 150 million years ago, meaning that they died out 79 million years before Albertosaurus existed. If they had lived at the same time and in the same place, though, Albertosaurus would have hunted Stegosaurus.
Here are some dinosaurs that began with A: Abelisaurus Allosaurus Afrovenator Albertosaurus Argentinasaurus Amphicoelias Apatosaurus Agutarama
T-rex was much larger than Allosaurus. It would be a colossal mismatch.
Giganotosaurus was 43 feet long and weighed somewhere between 6.5 and 14 tons. Allosaurus was 32 feet long maximum and weighed somewhere between 1 and 4.5 tons. Thus, Giganotosaurus was far larger, and thus the only hope for an Allosaurus fighting a Giganotosaurus would be to flee. Note that Allosaurus never would have encountered Giganotosaurus, as the former died out about 53 million years before the latter evolved, and they didn't even live on the same continents.
Allosaurus was dominant over Ceratosaurus, but Ceratosaurus would not be usual prey for Allosaurus. Carnivore almost never prey on other carnivores. It is possible though on rare occasions Allosaurus may hunt and kill a Ceratosaurus for food.
Here is my knowledge. Acrocanthosaurus was 40 feet long and wieghed 5 tons, while Allosaurus is 36 feet long and tiped the scales at 7,500 pounds. Acrocanthosaurus was larger and coul take more damage, while Allosaurus had speed and eyesight on its side. Who would win? Probably Acrocanthosaurus.
Most Allosaurus would have been killed by predators, other Allosaurus, or in struggles with prey or disease very young. The maximum lifespan of Allosaurus was about 28 years. If you are asking when Allosaurus went extinct, they died out about 150 million years ago.
suchomimus. allosaurus would be severely injured by its enemies claws and allosaurus with its weak bite force would usually flee. suchomimus was about 2 times bigger then allosaurus but suchomimus did not prey on large animals.its teeth,and snout were designed for catching fish and small dinosaurs. if forced it would battle and they did not live in the same period.
Adult Allosaurus never would have been hunted for food. However, young Allosaurus could have been hunted and killed for food by crocodiles, Ceratosaurs, Ornitholestes, or even larger Allosaurus, if they were cannibalistic.
Allosaurus definitely would have hunted young Brachiosaurus. It would ambush, then pursue and grasp the prey with its arms, and dispatch it with a bite to the throat. It is unknown whether Allosaurus hunted adult sauropods, but if they did, Allosaurus would have to mob the sauropod as a group and slash it repeatedly until the prey finally bled to death.
Yes, an Allosaurus's speed would have helped it to catch prey. Paleontologists estimate that their top speed was between 19 and 34 miles per hour, depending on the estimate you use.
Albertosaurus was a carnivorous dinosaur that primarily fed on other animals, such as smaller dinosaurs and possibly even juvenile individuals of its own species. Its diet would have mainly consisted of herbivorous dinosaurs like hadrosaurs and ceratopsians.
