The reading and lecture are both about the dinosaurs's crests. Whereas the reading put forwards three hypotheses to identify correct use of these crests, the lecture caste doubts on these hypotheses with three main points.
First, the reading states that the crests was used to enhance the capability of smell in order to expand the sensory receptor surface area. However the lecturer disputes this point. He states that brain of the dinosaurs were equipped enough to accommodate this feature, in order to increase the sense of smell.
Secondly, the reading claims that the crests helped dinosaurs to cool down. Nevertheless the lecturer refutes to this argument. He argues that in order to help the dinosaurs in cooling down efficiently, the crests should have been proportionate to size of dinosaurs, whereas the crests in actual are very small in size.
Finally, according to the reading the crests where used to phonate, in order to communicate with other members. On the other hand lecturer states that, with recent studies and comparison with current world's reptiles and birds, it has been proved that only one kind of dinosaurs were able to make vocal sound and most of the dinosaurs were not capable to making vocal sounds.
In conclusion, Although the reading and lecturer are about the crests found on dinosaurs. The hypotheses to shared by the reading where effectively challenged by the lecturer.
