How does a tyrannosaurus rex sleep

It is also true that giraffes sometimes do sleep laying down. Babies sleep with their legs pulled in under their warm bodies and their heads rested on top of their comfy stomachs. Perhaps if we studied the sleep habits of cows and elephants we can get a good idea about how triceratops or ankylosaurus might have slept. Most people think that cows sleep standing up.

However, cows actually sleep laying down, on their sides, and for up to 14 hours a day! They must be really bored! Elephants are the same. They sleep lying down and on their sides. Though, they can sleep standing up. Elephants often take naps while standing, but at night, they get down on the ground, lay on their sides, and sleep for hours.

So what can we glean from the sleep habits of these four-legged mammals? Since it only has two hind legs and two seemingly useless little arms, it is often wondered just how a T-Rex could lay down and especially get back up again.

Since the T-Rex was the apex predator of his time he might have slept like a lion, very comfortably and for long periods of time. Especially after a big brontosaurus steak burger and fries. It has long been expected that this pubic bone might have been used for the T-Rex to sit and to get back up. Stevens and Eric D. There have been a few fossils unearthed that seem to have preserved a dinosaur while sleeping.

The most famous and recent of these sleeping dinosaur discoveries is a dino called Mei long. Mei lived during the Early Cretaceous Period.

Other dinosaurs fossils that look as though they were sleeping are the Segisaurus, the Sinornithoides, and the Guaibasaurus. Pretty adorable for a metre-long murder chicken. There are plenty of aspects of tyrannosaur life that, much like the animals themselves, appear fuzzy. Bones, tracks, and skin impressions can only take us so far. Asking about daily dinosaurian life reminds us that T. They were real living, breathing animals that experienced life in their peculiar dinosaurian fashion.

If we want to know T. This article is more than 4 years old. Brian Switek. Tyrannosaurus rex was a sensitive lover, new dinosaur discovery suggests.

There were some nocturnal dinosaurs that would hunt at night, but the majority of dinosaurs would be awake during the day. We can use the current animal kingdom as a reference to see which dinosaurs might have been nocturnal or not. The dinosaur ecological system seems very similar to our current one, with some animals sleeping during the day and some during the night.

Many people are aware that nocturnal means animals or people that are awake during the night. Apparently if you are awake during the day and sleep at night you are diurnal.

The sleeping habits of the dinosaurs has long been in question by paleontologists. Just like we can determine the average speed of a dinosaur by using fossilized trackways and references to current day animals , we can use similar data to determine how they slept. The length of sleep the different dinosaurs had is nearly impossible to determine given the fossil record. This kind of speculation can only come from the modern world.

We can take modern references and apply that same logic to dinosaurs with similar features and natural status. The same can be assumed for dinosaurs. Perhaps the stegosaurs or hadrosaurs slept a few hours at a time and in herds the same way. Carnivores are known to sleep more than herbivores on average so the same can be assumed for the ancient world.

Tyrannosaurs likely would have slept any time they felt like it without worrying about threat of attack. The actual sleep lengths are impossible to know, however. We can know modern animals sleep durations by actively monitoring them, but we have no way of doing the same thing for the dinosaurs. Just like the current animal kingdom, there would have been many different ways the varying dinosaurs slept.

Some would have slept standing up, some would have slept in more of a sitting position and others yet in more of a traditional laying down position. There have been several dinosaur fossil discoveries that directly show that some dinosaurs curled up and slept just like modern day birds.
