Dinosaurs most likely had four-chamber hearts. They could provide dinosaurs with high blood pressure so that blood entered the head, which was far from the body. In addition, the presence of a four-chambered heart means that the creature is most likely warm-blooded, while all reptiles (including dinosaurs) also have a three-chambered heart. Such hearts allow a mixture of venous and arterial blood. In this regard, the organs of the body are supplied with mixed blood, and the level of metabolism decreases - which causes cold-bloodedness.In 2000, the skeleton of the Tescelosaurus dinosaur was discovered (I can talk about it in one of the following articles). It found something that scientists described as the fossilized remains of a four-chamber heart and aorta. This was the reason to believe that the dinosaur had a fast metabolism and warm-bloodedness.
