ደስ ዝብሉ ሓቅታት

Allosaurus had dozens of sharp, serrated teeth in its mouth, perfect for slicing meat.1

Its name means 'different lizard' because its backbone bones were light and hollow, which was unusual for a dinosaur of its size.1

Allosaurus lived from about 155 to 143 million years ago, during the Late Jurassic period.1

It was one of the most common large predators in its ecosystem, and many fossils have been found in the Morrison Formation.1

Some scientists think Allosaurus may have hunted in packs, but others think it was a solitary predator that only gathered in groups sometimes.1

Allosaurus had small, three-fingered hands, but its legs were large and powerful for running after prey.1

ብዛዕባ Allosaurus ብብዝሒ ዝሕተቱ ሕቶታት

?How big was Allosaurus?

Allosaurus averaged about 8.5 meters (28 feet) long, with the largest specimens estimated at 9.7 meters (32 feet). It weighed around 2,700 kilograms (about 6,000 pounds).1 3

?What did Allosaurus eat?

Allosaurus was a meat-eater that hunted large plant-eating dinosaurs like Stegosaurus, Diplodocus, and other ornithopods, stegosaurids, and sauropods. It may have also scavenged on dead dinosaurs.1 3

?When did Allosaurus live?

Allosaurus lived during the Late Jurassic period, about 155 to 143 million years ago. Some sources say 152 to 145 million years ago.1 3

?Where was Allosaurus found?

Most Allosaurus fossils come from North America's Morrison Formation, but some have also been found in Portugal. It lived in what is now the USA.1 3

?Was Allosaurus bigger than T. rex?

No, Allosaurus was smaller than T. rex. Allosaurus was about 8.5 to 9.7 meters long, while T. rex reached lengths of 12 to 13 meters.1

?Did Allosaurus hunt in packs?

Scientists aren't sure. Some think Allosaurus may have hunted in packs, but others think it was a solitary predator that only gathered in groups sometimes. There's evidence for both ideas.1 3

?How fast could Allosaurus run?

Up to about 34 km/h (21 mph), about as fast as a fast human runner. A computer model of its legs and muscles worked this out. Its big, strong legs were made for running after prey.1

?Did Allosaurus have feathers?

The sources don't mention feathers on Allosaurus. It is known to have had scaly skin, but no feather fossils have been found.1

?Why is it called Allosaurus?

Allosaurus means 'different lizard' in Greek. It got this name because its backbone bones were light and hollow, which was unusual for a dinosaur of its size.1

?Could Allosaurus swim?

The sources don't say whether Allosaurus could swim. It was a land dinosaur that walked on two legs, so it probably didn't swim often.1

ጽውጽዋይ ዘፍርስ

ጽውጽዋይ: Some people think Allosaurus was a slow, clumsy scavenger.

ሓቂ: Scientists think Allosaurus was a fast and active predator, with strong legs and sharp teeth for hunting live prey.1
