The latest research shows that T-Rex's skull has an air-conditioned function.
According to Science Daily, researchers from the University of Missouri, Ohio, and Florida have identified Tyrannosaurus Rex (T-Rex) dinosaurs that have an air conditioner in their heads.
Scientists previously believed that the two large holes in T-Rex's skull contained jaw-supporting muscles. However, Professor Casey Holliday of MU School of Medicine confirmed that the above opinion was incorrect.
"It is strange that a muscle grows from the jaw, rotates 90 degrees and walks along the cranial arch ... We now have a lot of evidence confirming how blood vessels in this area, based on research from crocodiles. As well as other reptiles," Holliday said.
This group of professors used thermal imaging cameras to test samples at the St. Crocodile Farm. Augustine in Florida. New evidence helps them come up with a new theory about the skull of T-Rex.
"The body temperature of a crocodile depends on its environment," said Kent Vliet, an expert at the University of Florida.
When it is cold, the thermal imagery shows large hot spots in the holes in the arches of warmed crocodiles, indicating the temperature inside the sample is rising. When it gets warmer, the upper holes shrink, as if they were turned off to keep the temperature fresh.
This is consistent with previous studies, which have demonstrated that the crocodile has a cross circulation system or an internal thermostat.
Holliday and his team took advantage of the data for checking fossils of dinosaurs and crocodiles to see how the holes in this skull changed over time.
"Like T-Rex, alligators have holes in their skulls, and they're filled with blood vessels… For over 100 years, we've been putting muscles into the same space as dinosaurs. With the results of current animal anatomy and physiology, we have a new perspective on the skull structure of T-Rex," said Larry Witmer, professor of anatomy at Ohio University.
