The Allosaurus became extinct during the Late Jurassic period, approximately 150 million years ago. The exact cause of its extinction is still debated among scientists, but some theories suggest that changes in climate, competition with other predators, and possibly even disease could have played a role in the decline of the Allosaurus population.

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.
2-6 meters was allosaurus long when it was born.
Allosaurus became extinct around 150 million years ago. The cause of its extinction is unknown.
Allosaurus fossils date to between 155 and 150 million years ago. Presumably they died out around 150 million years ago.
Speed estimates are very difficult for extinct animals, especially dinosaurs because they are so different from modern animals. However, paleontologists estimate that Allosaurus's top speed was between 19 and 34 miles per hour, depending on the estimate you use.
There is one accepted species in the Allosaurus genus. Its full Latin (or scientific) name is Allosaurus fragilis.
