The lecturer argues that the functions of the Lambeosaurus crests that revealed recently are not convincing. This contradicts the reading passage’s claim that there are several clues found that the crests had specific roles for its species. First, the lecturer contends that the Lambeosaurus didn’t use the crests to obtain mate. To be specific, the mates of the Lambeosaurus were likely to prefer the specific sounds not the appearance of their species. For example, when crocodile allure its mate, it uses special noisies. Because crocodiles and dinosaurs are the same kind of species - reptiles, so it means Lambeosaurus also used a similar method to obtain its mate. This casts doubt on the reading passage’s claim that by using the crests, the Lambeosaurus could attract its mate. Next, the lecturer asserts that the Lambeosaurus’s crests were not used for the combat. Of course, Triceratops used its horns, which was quite solid, to threaten other dinosaurs, however, the crests of the Lambeosaurus were hollow so it was too fragile to use for attacking other dinosaurs. This refutes the reading passage’s claim that one explanation insists that the Lambeosaurus used the crests for menace to other dinosaurs. Finally, the lecturer maintains that the crests could not provide the air when Lambeosaurus under the water for their meals. It was only small-scale hollow so that couldn’t provide enough amount of air to the Lambeosaurus. They were so immense that use the other way which might be deep breathing, to eat the preys that were located under the water. This counters the reading passage’s claim that Lambeosaurus’s crests were functioned to deliver the air while they eat.
