The reading and the lecture are both about pterosaurs. The author feels that they were not capable of powered flight. The lecturer challenges the claims made by the author. She is of the opinion that some evidences, however, suggest that they were able to make powered flight.
To begin with, the author argues that like modern reptiles, pterosaurs were cold-blooded. The article mentions that, however, powered flight requires a lot of energy, typical for warm-blooded animals. This specific argument is challenged by the lecturer. She claims that recent researches find that pterosaurs had dense, hair-like covering similar to fur, suggesting that they had metabolism, typical for warm-blooded animals to generate a lot of energy. Additionally, she says that they supplied enough energy to make high temperature for external conditions, a mark of metabolism.
Secondly, the writer suggests that there is a boundary for weight of animals that can be kept airborne by powered flight. In the article, it is said that pterosaurs were so heavy to flap wings fast to stay aloft. The lecturer, however, rebuts this by mentioning that their bones were hallow instead of solid, making their weight low enough to stay aloft. She elaborates on this by bringing up the point that despite the large frame sizes, they were, probably, capable of powered flight because of low weight.
Finally, the author posits that because animals capable of powered flight were able to take off from the ground, they needed to gain speed and jump to air. Moreover, it is stated in the article that pterosaurs were not able to do so, thus they needed powerful muscles, but they had too small legs for doing so. In contrast, the lecturer’s position is that birds capable of powered flight used only their two limbs: their legs. She notes that pterosaurs, however, used their all limbs to push off the ground, suggesting that they provided all energy enough to launch themselves into the air.
