Species: Z. linhaiensis (type).
Type: Carnivore.
Size: 3.5 meter wingspan.
Known locations: China, Zhejiang Province.
Time period: Campanian of the Cretaceous.
Fossil representation: Many specimens including four
articulated skeletons.
Zhejiangopterus
belongs to the Azhdarchidae group of pterosuars,
the same group that
includes the huge Quetzalcoatlus.
With the large number of fossils of
Zhejiangopterus discovered, it is one of the better
represented of all
the azhdarchids. Initially thought to have had a 5 meter wingspan,
study of available fossil material has called for a revision and
henceforth reduction of the total size to 3.5 meters. The wings were
relatively short compared to the body length, but were robust.
The
toothless beak was long
and pointed. Although there was no crest on top of the head, what
appears to be a reinforcing crest ran along the base of the lower jaw.
The antorbital fenestra was greatly enlarged taking up roughly half the
skull area. this would greatly reduce the weight of the head.
The
long legs on
Zhejiangopterus meant that it would have had a high
walking gait while
on the ground. This supports the hypothesis that the azhdarchids hunted
like modern day storks.
