Did T-Rex sleep standing up? There is no known answer for this question but based on the fact there’s no two legged animals that do this today, it’s pretty safe to say that T-Rex’s didn’t sleep standing up.

Some animals sleep upside down, others sleep sitting in trees, while others even sleep in the water (with extra air pockets helping with buoyancy). The same can likely be said for dinosaurs. Their size and status in the natural pecking order would have determined their sleep style. Examples of dinosaurs that might have slept standing up:
