The more a t-rex grows,the
shorter the arms get.T-rex
lived in the late cretacous
period.T-rex is not a type
of tyrrannosaurid,it's a
raptorid type of dinosaur.
People used to think t-rex
was slow,and could only run
up to 5mph,but now people
think t-rex was fast,and
could run up to 30mph.
T-rex has about 60 razer
sharp teeth.
