First, the professor asserts that pterosaurs would have been
warm-blooded animals, not cold-blooded like mordern reptiles. This was proven
by the fossils that contain hair and fur covering. Hhair and fur were the typically
the warm-blooded animals' features. It means maens that pterosaurs' metabolism was
faster than the reading passage's assumption. This casts doubt on the reading
passage's claim that the slow metabolism is was the reason why the dinosaurs
could not fly.
Next, the professor argues that pterosaurs did not have heavy weight. It
is true that pterosaurs were as large as a giraffe. However, when the
researchers studied y the dinosaurs' fossils, they found that their bones are
hollow and not solid. This means that, nevertheless they were had large sizes,
pterosaurs were had light weight. This refutes the reading passage's asserting that
their heavy weight could have detered the dinosaurs from flapping their wings
fast.
Finally, the professor contends that pterosaurs had a sufficient ability
to take off the ground. This is because the dinosaurs were different with
birds. While birds use only two limbs when they take off, pterosaurs could use
all their four limbs to push off the ground. Tthis would have made possible for
pterosaurs to run fast and jump high. This challenges the reading passage's
suggestion that they could not launch themselves into the air because of their
weak muscles in their back legs.
