It is unknown, but probably around 30-40 years.
It lived 90 - 100 years.
An allosaurus could grow to be 12 meters long.
it is 12m long
2-6 meters was allosaurus long when it was born.
The bulk of Allosaurus remains have come from North America, with material also known from Portugal and possibly Tanzania.
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.
39 feet
An allosaurus could grow to be 12 meters long.
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 had a maximum lifespan of about thirty years or a little less. Scientists determined this by looking at the growth rings in the bones of fossilized Allosaurus. That lifespan is actually longer than the lifespan of wild dogs and big cats, which only live around 15 to maybe 20 years, maximum.
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.
Allosaurus lived between 155 and 150 million years ago. This was during the Kimmeridgian and Tithonian stages of the Jurassic period.
