The reading presents three reasons why the Pterosaurs were not able to fly, but the lecturer poses some evidences against this statement.
To begin with, the reading highlights the first reason that ancient reptiles like Pterosaurs may be cold-blooded animals like the modern reptiles, so their slow metabolism cannot produce enough energy to fly. The lecturer, however, argues that the Pterosaurs may be warm-blooded animals because of their fur or hair covering their body found in the fossil. Therefore, they may have enough energy to fly.
Additionally, the reading suggests the second reason that Pterosaurs are too large to fly because of their size as large as Giraffe, but the lecturer explains that the hollow bone of Pterosaurs can lead them unusual light enough for their size to fly with flapping their wings.
Finally, the last reason is presented in reading that Pterosaurs' back legs are too weak to launch into the air. On the contrary, the lecturer points out that Pterosaurs can take off with four limbs on the ground, unlike the approaches of other birds. Besides, Pterosaurs could run or jump fast enough with their four limbs.
