Based on the given materials, the article as well as the lecture discusses pterosaurs, which were winged reptiles with size approximately as giraffe. Although paleontologists believe that these animals were able to fly by flapping their wings, known as powered flight, the author states several viable theories in order to reject this ability. That being said, the lecturer provides several ideas to concur with the fact that pterosaurs could have had skills of powered flight.
Initially, the writer says that ancient reptiles should have been cold-blooded as well as the modern reptiles, which leads to have slow metabolism. So, pterosaurs should not have had enough energy to participate in powered flights. However, the speaker explains that based on recent investigated fossils of these animals, they had got dense hair-like covering, which counts as a typical of warm-blooded animals. It provides materials for pterosaurs to maintain their body temperature even in cold weathers. Thus, as the fossils approve that these reptiles would have been warm-blooded, they should have had enough energy to take part in powered flights.
Second, the author proclaims that pterosaurs were so heavy to have ability of flipping their wings fast enough in order to stay aloft. Yet again, as the lecturer underscores, it is now discovered that these reptiles had anatomical features, which made them strangely light for their size. She exemplifies the animals' bones which were hallow, but not solid. This characteristic decreases their weights in proportion of their size. As a result, their weights were low enough to do powered flights.
The final point of contention between the reading and the listening passage is ability to taking off from the ground. As the writer thinks, since it has been discovered from these reptiles' fossils that they had got weak and small leg muscles, never did large pterosaurs have strong muscles in order to gain speed and jump as much as powered flights require, like birds. On the other hand, the speaker explains that there are some essential differences between birds and pterosaurs. These reptiles had got four legs in opposite to birds, which had two hind limbs for walking. Since modern flying animals are able to fly with four legs, pterosaurs also could have been able to fly. In addition, recent research shows that these reptiles could both run fast enough and jump high enough in order to participate in powered flights.
