According to the report on the website of focus on May 2, did dinosaurs sleep on their back or standing? Do you like to take a nap often, or sleep for a long time at a time? We don’t know the exact answer. But scientists have a full understanding of the sleep habits of a dinosaur: it is a wounded toothed dinosaur the size of a dog - Meilong. It is a close relative of birds.

Scientists have found two fossilized dinosaur skeletons in a sleeping position 125 million years ago. It seems that volcanic eruptions suffocated and buried these dinosaurs while napping.

These fossil skeletons have the same “house” sleeping position as today’s birds: the body is placed on folded legs, and the head is sandwiched between the forelimb and trunk. Birds sleep in this way to keep their heads warm. Perhaps this can show that some dinosaurs are also warm blooded animals.
