Pterosaurs were an ancient group of winged reptiles that lived alongside the dinosaurs Many pterosaurs were very large some as large as a giraffe and with a wingspan of over 12 meters Paleontologists have long wondered whether large pterosaurs were cap

The reading and listening material conflict with the viewpoint of whether large pterosaurs were capable of powered flight. The writer figures out that the attributes of pterosaurs made them hard to fly, while these opinions are contradicted by the lecturer.
First of all, the writer points out pterosaurs were probably as cold-blooded as modern reptiles, which means that they had a slow metabolism that could not generate enough energy to fly. The lecturer opposes this perspective by saying that pterosaurs might have hair covering, which could be used to maintain their body temperature. By the way, they can have a metabolism like warm-blooded animals and save more energy for flying.
Secondly, the writer argues that pterosaurs were too large that their weight might be over the limitation that allows animals to fly. The lecturer views this point from an opposite angle. According to her opinion, actually, pterosaurs had an unusually light airborne. Their airborne were holo and not solid, which shows that even though they kept a large body size, their weight was as low as the limit to the weight of animals that can be kept by powered flight.
Thirdly, the author states that large pterosaurs' back leg muscles were too small and weak to allow them to run fast enough or jump high enough to fly. By contrast, this point of view doesn't hold water. It is because they are not like small birds. They use four legs to jump and run, which means they are capable of having enough power to fly.
