"Dinosaurs had a slow growth rate throughout their lives, just like other reptiles," he continued, "but the largest and oldest Tyrannosaurus rex known to date, 'Sue,' only lived to be 28 years old. Tyrannosaurus rexes had a rapid growth phase during their development, during which their growth rate was quite high, almost gaining four jin of flesh every day. This explosive growth allowed the Tyrannosaurus rex to develop a massive body in a short period of time."
Ye Fan kept on, aiming to further enrich his son's understanding of the Tyrannosaurus rex.
"Dad, that Tyrannosaurus rex is really amazing, it could gain four jin of meat a day! But its lifespan seems rather short, just 28 years," Xiao Wu lamented slightly.
He thought that humans could live at least sixty to seventy years, with some reaching over a hundred years.
Who would have thought that a Tyrannosaurus rex could only live for 28 years!
It seemed quite short-lived!
