The Truth About T-Rex: New Study Shows Tyrannosaurs had Lips to Protect their Teeth

Tyrannosaurus rex, one of the most iconic dinosaurs, has long been depicted in movies and illustrations with its teeth fully exposed. However, a recent study suggests that T-Rex and its relatives had lips that covered their teeth when their mouths were closed. In this article, we will explore the findings of the study and what they reveal about the appearance and behavior of these giant predators.

The Study

The study, conducted by a team of researchers from the University of Edinburgh and the University of Kent, used advanced imaging techniques to examine the skulls of several species of tyrannosaurs. The researchers found that these dinosaurs had a fleshy covering on their jaws that would have protected their teeth when their mouths were closed. They also found evidence of a keratinous material, similar to the material found in bird beaks, on the lips of some of the specimens.

The Implications

These findings have significant implications for our understanding of how T-Rex and its relatives looked and behaved. It suggests that these dinosaurs had a softer, more bird-like appearance than previously thought, with lips and a beak-like structure covering their teeth. This could also mean that they were more vulnerable to injury and infection in their mouths than previously thought.

Furthermore, the study suggests that tyrannosaurs may have had a wider range of feeding habits than previously believed. With lips covering their teeth, they would have been better suited to feeding on prey that was smaller or more delicate than their usual prey, such as animals with tough hides or shells. This could have allowed them to exploit a wider range of food sources and adapt to changing environmental conditions.

The Debate

While the study provides strong evidence for the presence of lips on tyrannosaurs, it has not ended the debate on this topic. Some paleontologists have raised concerns about the methods used to study the fossils, suggesting that the imaging techniques may not be reliable enough to accurately detect soft tissue. Others have pointed out that not all species of tyrannosaurs may have had lips, and that more research is needed to fully understand the diversity of this group of dinosaurs.

So, the recent study provides fascinating insights into the appearance and behavior of T-Rex and its relatives. It suggests that these dinosaurs had lips and a beak-like structure covering their teeth, which could have influenced their feeding habits and vulnerability to injury. While the study is not without controversy, it represents an exciting advance in our understanding of these iconic creatures.
