Like large animals today, Ankylosaurus just slept in the forest and didn't have any dwellings. Unlike most animals, though, even a sleeping Ankylosaurus was relatively impermeable to attack because of its bony armor. If it were attacked, it would soon wake up and then probably kill its attacker with a strike from its tail club.
Brontosaurus, more accurately called Apatosaurus, was a 75 foot long, 18 to 25 tons herbivore. Like large animals today, Apatosaurus didn't sleep in any sort of dwelling, cave, etc. They simply slept in the open or in the forest for short periods of time. Apatosaurus would have spent nearly the entire 24 hour day eating, and thus they didn't sleep very much.
Peacefully, under ground. They're dead, remember?
In the ground because they are dead.....unfortunately
On the ground I believe. Maybe with closed eyes, but that's debatable.
it sleeps out in the opening
you need help fool!
Yes. Here's a definition:den: a cave. Dinosaurs sleep in dens.
yes. all animals sleep
Yes.
All terrestrial vertebrates require some form of sleep. We can't learn about how dinosaurs slept from their fossils, but because birds and crocodiles, their closest relatives, sleep, it is safe to assume all dinosaurs did, too.
To keep warm.
The occupation of the dinosaurs was pretty much the same as all animals: eat, sleep, reproduce.
Hang around. Eat, sleep, have sex and produce little baby dinosaurs. You know how it is.
True. During winter, they have to sleep in dens to keep warm.
depends how they sleep some lay down and some sleep standing up like a guard
just sleep aand walk and eat a bit1. That's all
Presumably yes, since modern land vertebrates do so as well.
A baby dinosaur should go to sleep at 6:00 because it will be light out and easy to see bigger dinosaurs at that time. Unlike humans we go to sleep when we feel like it but babies sleep when they want.
