Scientists have previously believed that the roof of the skull of the tyrannosaur rex has two large holes, known as dorsotemporal fenestra, which are filled with muscle to help muscles. of dinosaurs with jaw movements.

Alligators, crocodiles, and T. Rex have large holes in their skulls

Casey Holiday, professor of anatomy at the University of Missouri, and colleagues, however, have discovered evidence that provides new information about the T.rex Chapter.

In a study published in The Anatomical Record on July 1

, researchers examined alligators using a thermal image that translates heat into visible light. Like T.rex, alligators and crocodiles also have holes in the roof of their skulls.

The alligator body depends on the environment. Researchers noticed that when it was cooler and animals were trying to warm up, thermal images showed large hot spots in the holes of the alligator skull, which showed an increase in temperature.

Later in the day when it's warmer. , the researchers noticed that the holes look dark, as if they were turned off to keep the animals cool.

Holiday and his colleagues then matched the thermal imaging data of the dinosaurs with that of T.rex fossils to see how the two

study revealed that the holes in the roof of T.rex's skulls were filled with blood vessels disputing earlier hypotheses about the anatomy of the head of a prehistoric predator.

"The relevant anatomical features argue for the rejection of the. By default – that the well is muscular – because of a complete lack of osteological correlates reflecting muscle attachment. The most supported finding of soft tissue is that the anterior parietal well is a large vascular structure. tissue, "the researchers wrote in their study.

Built-in air conditioning to keep T.Rex dinosaurs cool

Holiday explained that terrestrial predators like T.rex will need the ability to shed heat because it generates a lot of body heat. A thermal window in their head would help. A special set of blood vessels in their skull could act as a way of regulating their body and brain temperature.

"Dinosaurs were probably warmer than we are used to thinking, more like birds than lizards," Holiday told CNN. "Being warm-blooded will allow them not to rely as much on the environment as cold-blooded lizards, but also control their own body temperature through internal means."
