In the reading passage there is ample support for the author's claim that the Lambeosaurus's crest on its top had particular roles. However the professor in the lecture gives several reasons as a rebuttal to the author's point. (마침표)
Fisrt First, the professor contends that it is doubtful, that the crest is was used for finding their mates. Most reptiles rely their attrectioning mates mate-attracting habits on behaviors or sounds. For example, male crocodiles, the most similar reptile to the dinosaurs, they lift their head up and slam the water hard which to makes noise. This behavior is to attract female crocodiles. This casts doubt on the reading passage's claim that the crest were used to attract mates, specifically and that female liked bigger crest.
Next, the professor insists that it is unlikely that the crest were used in their combat. Their Fossils has have been excavated from the site (무슨 site?), and the crest were placed in backward, while forward one is needed for the combat while it should have faced forward to be used for combat. Not only that, the inside of the crests were was empty and very fragile, which means it was not applicable for combat. This counters the reading passage's assertion that the crest were was employed in combat to protect themselves from bigger predators.
Finally, the professor argues that the crest were was not used for their supply of air air supply when they were having aquatic meal eating under water. As Lambeosaurus was a massive dinasaur, plenty of oxygen were was needed, while the crest's capability for air was not enough for the purpose. To supply air in the water, breathing out of the water would have been a better choice for them. This refutes the reading passage's suggestion that the crest offered air while they were in under water (띄어쓰기), keeping them inside water for a long period.
