The article outlines three possible explanations regarding the function of lambeosaurus crests: sense of smell, cooling and for producing sounds. The lecturer, on the other hand, argues that it is unclear if these functions proposed are true.
First and foremost, to improve the sense of smell, the author of the article notes that crests had many blood vessels and that it is logical to believe that lambeosaurus had a developing smell sense because many current animals with a high smell sense have the same density blood vessel pattern. The speaker, however, questions if this is correct and says that the cavity brain of lambeosaurus, which contains nerves connected to smell, is tiny, making it impossible to support that lambeosaurus evolved a smell sense.
Second, the author emphasizes that lambeosaurus crests aid to control internal temperature by increasing surface area and letting body heat to escape, as seen in other species such as the stegosaurus. The speaker, on the other hand, claims that the surface area of crests does not represent an advantage for temperature regulation because its size is smaller in comparison to other species such as stegosaurus, which have a representative high surface area allowing them to regulate their internal temperature.
Finally, the author claims that crests were employed to generate sounds, maybe to communicate, and a developed inner ear in lambeosaurus funding in fossils supported it. In contrast, the speaker points out that in only one species of lambeosaurus discovered excellent hearing abilities, therefore there is no proof that all species use crests to communicate, and researchers are skeptical of this notion.
