Too much evidence for that, thanks to how many almost complete t. rex skeletons we have + the fact that almost all giant carnivorous dinosaurs had tiny arms. However, there’s a non-zero chance they were fluffy in at least some places, and a high chance they were incredibly fluffy as chicks, given how fluffy one of their close relatives is known to be.
So my takeaway from this is that if I had an enormous tail implanted for counterbalance, I could also have my arms shortened in an act of extreme body modification.
(But seriously, that was super interesting. Thanks for posting.)

Also they weren’t even the most extreme example of tiny arms
Is there an evolutionary explanation for why they had short arms? I was being rather flippant, but this is actually fascinating.
I think PBS Eons actually did an episode on this. Iirc long arms would get in the way
Edit: found it!
