What was the life span of allosaurus?

Answer 1

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.

Answer 2

Normally, an average meat eating allosaurus would live for up to 90 - 100 years, just like a normal human.

Answer 3

An average adult Allosaurs grew to be about 28 feet long. Very large individuals grew up to 32 feet long.

Answer 4

It is unknown, but probably around 30 years.

Answer 5

The maximum lifespan of Allosaurus was 28 years. However, most of them died long before they reached that age.

Answer 6

Allosaurus fossils date to between 155 and 150 million years ago. Thus, they probably existed for about 5 million years.
