Dinosaurs relied on an “evaporation” area to dissipate heat in the head

Dinosaurs developed in many different ways over time, but all faced the same problem, especially in regard to heat dissipation in my head. In fact, the level of overheating is too high and can damage the brain. According to a new study published in Anatomical Record, the largest dinosaur solved the problem in a variety of ways and used a possible dissipation scheme.

Small dinosaurs were able to hide in the shade during the hottest days of the day, but large dinosaurs such as long-necked sauropods and armored dinosaurs found it more difficult to avoid overheating. Many dinosaur species relied on evaporation, the technology still used to cool things. In particular, as far as our body is concerned, it is evaporative cooling by sweat that causes the temperature to drop slightly when the body itself overheats.

Researchers study birds, the modern parents of dinosaurs, and understand how they rely on this type of cooling. They followed the blood flow of the evaporative cooling site to the brain. This is an inherently moist area, such as the eyes, nose, mouth, that cools the blood as it goes to the brain. They also measured bone channels and grooves that carry blood vessels.

As Ruger Porter, the lead author of the study, explains, “The bone grooves and grooves found in modern birds and reptiles are linked to dinosaur fossils. Using these bone tests, we wanted to see how their blood flow patterns can be restored and how they deal with their thermophysiology and heat.”

They concluded that larger dinosaurs had a vascular pattern that emphasized specific areas of cooling, typically areas of different genus or species.

For example, sauropods emphasized both the nasal cavity and mouth as cooling areas, whereas sauropods emphasized the nose.
