Plausible, yes. But I'm still interested in the question I asked a day or two ago: does anyone know ANY extant tetrapod in which the juveniles can run faster than the adults? I can't think of any -- which of course doesn't mean there aren't any, hence the question.
I think the following question is strongly related: Is there any
extant animal (apart, perhaps, from humans) that needs more than 15
years to reach full size and has a life expectancy of only 30 years?
Because with the growth curve drawn by Erickson (?), selective
pressure must be very strong for the long time T rex juveniles have a
mass of below 1-2 tons. Thus selective pressure may be different from
extant animals.
