It’s a question that has puzzled people for generations: do dinosaurs have ears? For years, scientists have attempted to answer this question by studying fossils and other evidence. But the debate rages on. Some say that there is no way to know for sure, since we can’t see into the minds of dinosaurs. Others claim that certain features of fossils suggest that they did in fact have ears.

In this article, we will take a look at the evidence on both sides of the argument. We will also hear from experts in the field who have weighed in on this fascinating question.
So, do dinosaurs have ears? Let’s find out.
There’s clear evidence in the fossil record that dinosaurs used to have inner ears and well-developed hearing. A great example is Sue, the famous Tyrannosaurus rex at The Field Museum in Chicago. When scientists CT scanned her skull, they found an inner ear cavity that was similar to that of modern reptiles.
The scientists found that a tiny inner ear bone, known as a stapes, had been preserved in the fossils of this dinosaur. It’s a tiny bone located within the inner ear that transmits sound vibrations to the eardrum. Sue would’ve been able to hear the noises of her Late Cretaceous surroundings since she could have heard everything clear up until about 77 million years ago when modern animals evolved (as described previously).
Other evidence that dinosaurs could hear comes from the use of new technologies by researchers to look at dinosaur remains. By using CT scanning equipment and 3D computer visualization, palaeontologists have been able to get a better idea of what the brain cavities of fossilized dinosaurs looked like. With the progress of science we can wonder if it is possible that dinosaurs come back in 2050, find out in this article.
By studying the shape and size of brain cavities in dinosaurs, researchers can learn about their sense of hearing. It has been determined that some dinosaurs had large forebrains, which indicates they probably had a strong sense of both smell and hearing.
What About Outer Ears?
Ears are composed of cartilage and skin, which aren’t the most robust materials to fossilize. As a result, paleontologists search for answers in modern animals. Birds and reptiles are distant relatives of dinosaurs, but they lack big ears. It appears incredibly unlikely that dinosaurs would have large flappy ears, given their close living relatives’ small pointed ears.
Birds have ear holes. These are small holes below and behind the eyes. When these ear apertures are big, they’re difficult to detect due to the feathers covering them. It appears that dinos had similar ear apertures, which may have been covered in feathers as well.
Could Dinosaurs Hear One Another?
Based on the research conducted thus far, it appears that dinosaurs could hear each other just fine. They had well-developed inner ears and their brain cavities indicate they probably had a strong sense of both smell and hearing.
But some experts say that we can’t be sure how well dinosaurs could hear. The reason for this is that we don’t know what kind of sounds they made.
Dinosaurs may have produced sounds that were too high or too low for our human ears to hear. We also can’t be sure how good their hearing was compared to ours.
However, we do know that some dinosaurs had the ability to make very loud noises. The Tyrannosaurus rex, for example, is thought to have produced sounds that were as loud as 140 decibels. To put this into perspective, a jet engine taking off produces about 120 decibels of sound.
So, even if we can’t be sure how well dinosaurs could hear, we know that they were probably able to make quite a racket.
Did T. rex Have Good Hearing?
No one knows for sure how good T. rex’s hearing was, but scientists believe that it was quite hypersensitive. This is because the cochlea, a bone in the inner ear, was remarkably long. In animals alive today, this is usually associated with the ability to hear low-frequency sounds very well.
So it’s possible that T. rex had excellent hearing. This would have come in handy for hunting, as they could have easily heard their prey from a distance. It would also have helped them to communicate with other members of their species. We can only imagine what kind of sounds a T. rex would have made!
Did Dinosaurs Have Ear Bones?
One of the most interesting things about dinosaurs is that we don’t know everything about them. For example, scientists are still debating whether or not some dinosaurs had ear bones. The Dilophosaurus is one of the dinosaurs in question. This genus of theropod lived in North America during the Early Jurassic period, about 193 million years ago.
Some scientists believe that the Dilophosaurus did have ear bones, based on the presence of small cavities in the skull that could potentially have housed these bones. However, other scientists argue that these cavities could have served another purpose, such as accommodating blood vessels or air sacs.
Do Reptiles Have Ears?
Believe it or not, not all reptiles have ears. In fact, only a small number of reptiles are able to hear at all. One group of reptiles that do have functioning ears is the crocodilian, which includes crocodiles, alligators, and caimans. These reptiles have external ear openings that are connected to the inner ear by a series of bones.
This allows them to hear low-frequency sounds, such as the calls of other crocodilians. Snakes also have some hearing ability, although their ears are internal and relatively simple in structure. They are able to pick up vibrations from the ground, which helps them to sense the approach of predators or prey.
Finally, turtles and tortoises are also able to hear, although their hearing is not as acute as that of other reptiles. In general, reptiles with external ear openings tend to have better hearing than those with internal ears. However, even reptiles with functioning ears can only hear a limited range of frequencies.
So, do dinosaurs have ears? The answer is complicated. We know that some dinosaurs had well-developed inner ears and their brain cavities indicate they probably had a strong sense of both smell and hearing. However, we can’t be sure how well they could hear because we don’t know what kind of sounds they made.
Additionally, we don’t know if all dinosaurs had ears. Scientists are still debating this question for some species. In general, reptiles with external ear openings tend to have better hearing than those with internal ears. However, even reptiles with functioning ears can only hear a limited range of frequencies.
