Large Pterosaus: The Possibility Of Powered Flight

The reading claims that large pterosaus were capable of powered flight, however, the professor find all the ideas mentioned by the reading passage dubious and think that they may were capable of powered flight and present some reasons to refute them all.
The author argues that pewrosaus were cold blooded since modern reptiles are cold blooded too, therefore they were not able to produce a lot of energy which is needed for powered flight. Conversely, the lecturer brings up that this reason is questioned by recent fossil remains due to the fact that fossil remained show that they had hair like the fur of the birds which shows that they were warm blooded like all fury birds and this furs could keep them warm enough and maintain high temperature,
