What is one interesting fact about allosaurus the dinosaur?
Allosaurus probably had a lifespan of about 28 years maximum.
Although they didn't reach their nearly full size until they were
about 20 years old, they reached sexual maturity by age 10. This
was an adaptation because most Allosaurus would never live long
enough to reach full size, but this way more of them still had a
chance to reproduce before they died.
