The author of the reading article and the lecturer both discuss whether large pterosaurs, an ancient group of winged reptiles that lived alongside the dinosaurs, were capable of powered flight or whether they were able only to glide. The author offers some hypotheses to claim that pterosaurs were not able to fly by flapping their wings. However, the lecturer casts doubt on these hypotheses and disputes with each of the author's theories by providing several counter-arguments.
To begin with, the author expresses that the ancient reptiles such as pterosaurs were probably cold-blooded because modern reptiles are cold-blooded. Such cold-blooded animals typically have a slow metabolism and are unable to produce lots of energy. As a consequence, pterosaurs could not have the ability to powered flight, which requires a great amount of energy. Nevertheless, the lecturer points out that the ancient pterosaurs actually had dense hair, like a feather, covering their body to keep their body temperature high. This suggests that the pterosaurs might be warm-blooded animals. Hence, the pterosaurs should have the ability of powered flight.
In addition, the author declares that pterosaurs that were as large as a giraffe were probably too heavy to fly by flapping their wings fast enough to fly. Nonetheless, the lecturer states that the pterosaurs had some features that kept them unusual light. In fact, most if not all of the pterosaurs' bones were hollow instead of solid, which might keep their weight low and thus, they would be capable of flapping their wings to fly.
Finally, the author reveals that all animals with powered flight are able to take off from the ground such as birds taking off by jumping from their legs or running to gain speed to jump. But such methods would not have worked for large pterosaurs. Large pterosaurs would have needed big and powerful muscles in their back legs to launch themselves into the air, but they did not have this kind of back legs. By contrast, the author asserts that the large pterosaurs were not like birds to use these kinds of methods to fly. As a matter of fact, the large pterosaurs were more like the bats, which means that they were able to use four limbs to run fast and jump to launch themselves into the air and fly.
