Homo sapiens has balancing long arms and no tail.
Tyranosaurs had short arms and big heavy balancing tail.
Superficially, a T-Rex doesn't look dissimilar to over 100 million
years worth of other dinosaurs. Point the Google towards
"Allosaurus." It was as likely "cold blooded" as T-Rex as "warm
blooded." And of course they are clearly different species,
getting into the details here, but superficially they are very, Very
similar.
T-Rex didn't spring from the air. What we see is the result of
countless millions of years of selective pressures, AND the
lack there of.
If there isn't pressure to change, transform, then it's not going
to, absent any indirect pressures... like the claim that floppy
ears on a dog aren't so much selected for, but "Came along
for the ride" as they evolved away from aggression.
So, yes, the tiny arms may not have been selected for. Maybe
they were. Maybe they grabbed hold their prey and spun like
a crocodile, the "Death Roll."

Big arms could have gotten in the way, invited injury. Or, they
could have just been unnecessary so if any "Smaller arms"
mutation cropped up there was nothing stopping it from taking
root...
The point is, we are NOT talking about "Intelligent Design." There
is no conscious choice here. The basic dinosaur model is not
going to change, absent some pressure -- environmental or
genetic -- to do so. The body type remaining so similar over the
span of the dinosaur reign speaks to the adaptability of that
body type, not necessarily a continuation of the lifestyle and
environment.
Man, I'm bored...
