Tyrannosaurus rex had a life span just under thirty years. They had a major growth rate increase during their teenage years. At about age twenty, a T-rex would have been mature.
T-rex! If you ask a 5 year old he will say T-rex. If you ask an 80 year old they will say tiger or T-rex.
Yes, if mosquitos that are preserved in amber that sucked the blood of a T-Rex could be harvested, the DNA sequence of the T-Rex could be extracted and replicated, and, combined with that of common frogs, could be used to clone a T-Rex. Source: Jurassic Park
As fast as T-Rex could run.
t-rex
The T-rex disappeared in about 65,000,000/65 million yrs. ago.
Uh maybe around like 20 Raptors could kill a t-rex
No
When T-Rex lived there were no cows, so the answer is none.
yes
Depends on how fat it was... Glad I could help!
The tail of a T. rex primarily served to balance the weight of the rest of its body and its massive head. Contrary to its depiction in Jurassic Park T. rex probably could not run fast.
