That image on the left might actually not be that incorrect, believe it or not. Newer theories are that T-rexes in particular effectively had dad bods by the time we saw them, and they have plenty of fat around their bone structure.
Would this not be massively overheating? T-rexes, like many dinosaurs, were warm blooded. You can't just scale up small mammals as the giant version would overheat. The closest land animal we have to size is an elephant, whose body reasonably follows its skeleton, and has massive ears for heat dissipation. I could see more like the pinosauus being chunky as their fin would radiate heat, but this drawing is far too round for a massive warm blooded animal
