*Paleontologists at University of Texas have published a new study suggesting that the protruding teeth of Tyrannosaurus rex were actually covered by lips.*

For decades, paleontologists have debated whether or not T rex had lips. Many experts believed that the dinosaur's teeth were too large and sharp to be covered by anything. However, the new study provides evidence that T rex lips did exist.

The researchers examined a fossilized T rex skull and found a number of anatomical features that suggest the presence of lips. These features include:

*A groove along the edge of the jaw that matches the size and shape of lips

*Bony ridges on the lips that would have provided support

*Fine lines on the upper jaw that indicate there was once skin and tissue

The researchers also compared T rex to other dinosaurs and found that there are no other known dinosaurs with protruding teeth that also had lips. This suggests that T rex lips were a unique feature of this dinosaur.

The study concludes that it is "highly likely" that T rex had lips and provides anatomical evidence that support this conclusion.

Why Did T Rex Have Lips?

The researchers speculate that T rex lips may have been useful for a variety of purposes. These purposes include:

*Protecting the teeth: The sharp teeth of Tyrannosaurus rex were made of bone and could easily be broken if they impacted any hard surfaces. The lips may have helped to protect the teeth from damage.

*Grasping and holding prey: The lips may have helped T Rex to grip and hold onto prey.

*Communication: The lips may have been be used for display purposes or communication, indicating emotion and threat.

Scientists continue to learn more about Tyrannosaurus Rex as they make further advancements that provide new insights into the habits and physical features of these ancient creatures.
