TPO47-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 capable of powered flight (flying by flapping their wings) or whether they were able only to glide. Several arguments have been made against powered flight.

Doubters point out that since modern reptiles are cold-blooded, ancient reptiles such as pterosaurs were probably cold-blooded as well. Cold-blooded animals typically have a slow metabolism and are unable to produce a lot of energy. Powered flight is an activity requiring a lot of energy, which is why all modern vertebrates that fly are warm-blooded, not cold-blooded. It seemed unlikely that pterosaurs would have been able to generate the energy needed to fly.

Second, there is a limit to the weight of animals that can be kept airborne by powered flight. Pterosaurs that were as large as a giraffe were probably so heavy that they would not have been able to flap their wings fast enough to stay aloft for any length of time.

Third, all animals with powered flight are able to take off from the ground. For example, birds take off by jumping from their legs or running to gain speed and then jumping. But these methods would not have worked for large pterosaurs. Large pterosaurs would have needed big, powerful muscles in their back legs to launch themselves into the air, and we know from fossilized bones that their back leg muscles were too small and weak to allow the pterosaurs to run fast enough or jump high enough to launch themselves into the air.

Both the reading and lecture discuss The Pterosaurs which is an ancient reptile that lived in the same time with the Dinosaurs. The author is of the opinion that the Pterosaurs was unable to flight and provides three reasons for support. On the other hand, the professor asserts that these reasons are unconvincing by refuting each reason.

To begin with, the reading claims that the pterosaurs was a cold blood reptile so has not enough energy to handle flight. However, the speaker says that these reason is not exact because their body has a dense hired cover that is maintained their body temperature so their metabolism was more like the warm blood animals. As a result their body can supply enough energy to handle the flying action.

Secondly, the author asserts that the mentioned animal has a large weight so cannot push from the earth .Conversely, the lecturer contends that despite the fact that these animals looked very huge, because of their special anatomy they did not have a high weight that prevent them from flying. Then, she explains that their bones structure is hollow so their weight decrease than what it seems. As a result they can flight in spite of huge body.

Eventually, the article mentions that their take off is like birds and did not effective. On the contrary, the professor explains that actually the Pterosaurs take off is really deferent from birds. Owing to the fact that birds use only foots for walking and take off but these animals walk on all limes. As a result, they can use their front legs to push from earth and finally they can easily lunch to the air.
