Did tyrannousaurus rexes sleep standing up?

Question

I don't see how they would get back up if they didn't.

Answer 1

I have no idea, but that is a great quesiton.

Q: How did T. rex sleep? Did it sleep standing up?
A: T. rex probably slept standing up like a horse or sitting on its big pubic boot, a bone in its pelvis. I don't know if it snored, but it probably roared when awake, and one Japanese scientist thinks it sounded like a big belch. It probably had bad breath from eating rotting meat and not brushing between meals! (Don Lessem)

Answer 2

They could have. Check out the new King Kong movie. There are several T-rex's that fall and get up while fighting Kong. They did it quite cleverly too because I always wondered what would happen if one ever fell over. Models don't give you an answer... they just lay there..... motionless.
What about a kangaroo? They must fall over and their design is similar to a T-rex. Maybe on line you could find a clip of a kangaroo getting up after falling.
Have a great day!!!

Answer 3

I don't think we'll ever know...however, my guess would be that they did. I base this on the behavior of their closest living relatives, birds...many of which sleep while perched. I suppose it's possible they could have sat like a bird a nest does and slept that way. I think it's quite unlikely they laid down on their side.

Answer 4

We'll never know... and never get the chance to go T-Rex tipping.
