Which dinosaur had the biggest teeth?

t-rex Hydraxon said: I actually think that the largest teeth belonged to the Kronosaurus, as in my research I found it has teeth up to 23 cm long!

Who wins allosaurus or ceratosaurus?

Allosaurus was 28 feet long and weighed somewhere between one and two tons. Ceratosaurus measured about 20 feet long, and weighed between half a ton and a ton. Allosaurus was significantly larger, so it would almost certainly win a fight with Ceratosaurus, but Ceratosaurus could probably run away if necessary.

What some awesome facts about Allosaurus?

Allosaurus was the top predator of the Jurassic period. There were three known species, A. Atrox, A. Fragilis, and A. Amplexus, although some scientists believe there may have been as many as seven. The largest was Allosaurus Amplexus, up to 40 feet in length.

Does anything eat the allosaurus?

No, allosaurus was the top predatore of its age.

How long is too long to wait for him to pop the question?

Young people today don't seem to get married that early and have children later in life as well. They usually want careers, do some traveling and have some fun first. There is really no time you can set, but personally, I wouldn't wait more than 2 years. As the old saying goes .... "If you don't want to buy the cow, you ain't getting the milk for free!" I've always gone for commitment. Good luck Marcy

What did the Allosaurus eat?

Allosaurus hunted any herbivorous dinosaurs that it could catch. Prey would have included Dryosaurus, Stegosaurus, and Camptosaurus. They may have even hunted and eaten sauropods, such as Apatosaurus, Diplodocus, Brachiosaurus, and Camarasaurus.

Which would win allosaurus or t rex?

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.

What is the closest living relative to an allosaurus?

i think it would be... an ostrich, a crocodilia, a bird, or an alligator :3

How did the allosaurus defend itself?

Young Allosaurus were either protected by their parents or simply ran to escape danger. Adult Allosaurus were 28 feet long and weighed somewhere between 2,200 and 8,800 lb depending on whose estimate you use. Because they were the largest predators in their habitat, the only significant threat to adult Allosaurus were other adult Allosaurus. They would have fought each other mostly by biting, but they may have also used their relatively strong arms and struck each other with their claws.

How did the allosaurus catch its food?

It is unknown whether Allosaurus hunted prey animals far larger than itself, such as adult sauropods. If it did, it is believed that Allosaurus would have mobbed the prey animals and slashed them, causing them to eventually bleed to death.

However, it may have only hunted young sauropods and other herbivorous dinosaurs such as Camptosaurus, Dryosaurus, and Stegosaurus, and simply scavenged on adult sauropods. To hunt these dinosaurs, Allosaurus probably would have hunted alone by ambushing them, then chasing them at a top speed of between 19 and 34 miles per hour. When Allosaurus caught up, it would grasp the prey with its hands and then dispatched it with bites to the throat.

What eon did the allosaurus live in?

Eon: Phanerozoic

Era: Mesozoic

Period: Late Jurassic to Early Cretaceous

Time range: 155 to 140 million years ago

When did the allosaurus become extinct?

Allosaurus fossils date to between 155 and 150 million years ago. Presumably they died out around 150 million years ago.

When did the Allosaurus live?

Allosaurus fossils date to between 155 and 150 million years ago. This was during the Kimmeridgian and then the Tithonian stages of the Jurassic period.

Who would win brachiosaurus vs allosaurus?

brachiosaurus would win because is more bigger than allosaurus

How long is a full grown allosaurus?

An adult allosaurus probably measured, on average, 28 feet in length. In metric units, that is 8.5 meters. The largest confirmed Allosaurus was 32 feet long, or 9.7 meters.

How strong of a bite force did the allosaurus have?

It had a stong bite and could easily tear flesh.

Can a t-rex eat a allosaurus?

Firstly, T-rex lived over 80 million years after Allosaurus, so they never would have encountered each other. However, T-rex outweighed Allosaurus by about three times, if not more, and had a very powerful bite force, while Allosaurus is estimated to have had a relatively weak bite force. This means T-rex could probably kill an Allosaurus in a fight, and if it did, it would have eaten it. However, Allosaurus would be very risky prey, so I doubt that T-rex would have hunted Allosaurus if they did coexist.

What era and period is the allosaurus from?

The Allosaurus lived 150 million years ago. That was during the Jurassic period. The Jurassic period was part of the Mesozoic era.

When was allosaurus named?

Allosaurus fragilis received its name in 1877. It was named by Othniel Charles Marsh. Allosaurus means "different" or "strange" lizard, and the species name "fragilis" means fragile, referring to the features of the vertebrae that reduce its weight.
