The reading and the lecture are both about the flight capacity of an ancient group of winged reptiles, the pterosaurs. The author of the reading believes that the pterosaurs were not able to fly, whereas, the lecturer casts doubt on the claim made in the article. She thinks that they were able to take off, jump in the air and fly.
First of all, the author points out that such as modern reptiles are cold-blooded so were the ancient reptiles. It is mentioned that this type of metabolism is not able to provide enough energy to the pterosaurs to fly. This point is challenged by the lecturer. She says that recent fossils with a dense cover of hair and fur have been discovered, and since only warm-blooded animals have hair and fur, the pterosaurs were most probably warm-blooded animals, therefore they had enough energy to sustain a flight.
Secondly, the author contends that the pterosaurs were too heavy to be able to flap their wings fast enough and flying for long distance and time. The lecturer rebuts this argument. She elaborates in this mentioning that the anatomical features show that the bones are hollow and this reduce sensibly the weight of these reptiles.
Finally, the author states that the pterosaurs muscles were not developed so well to make these animals able to take off as other birds do. The lecturer, on the other hand, posits that modern birds use two limbs for walking and launch themselves in the air. She puts forth the idea that pterosaurs used four limbs; therefore, they would have had the necessary strength to push themselves from the ground, jump in the air and fly.
