Zambelli/1973 Distribution:Zorzino limestones, Cene, Italy Rhamphorhynchoidea/Campylognathoididae Wingspan = 1 m/Skull length = 6 cm Eudimorphodon is the oldest in the pterosaur
discovered. It had the long tail which has two kinds of
teeth of the form where it differed for preying on a fish or
an insect, and has a lozenge-like flap at a
tip. "hairy demon" Describer :Sharov, 1971 Rhamphorhynchoidea／Anurognathidae southern Kazakhstan Age: Late Jurassic（150 million years ago） The discovered fossil showed having had feathers and the
body of SORUDESU was covered with the thick fur. It seems
that however, the mammalian fur was close to the feathers
which were different and developed from the skin in
which Scale grew. It is thought from this that the
pterosaur was a warm-blooded animal.
"jaw lizard" Describer: von Meyer,
1834 Distribution: Southern Germany Pterodactyloidea／Cycnorhamphus／Ctenochasmatidae TiSize: Skull length = 28cm. Wingspan estimate = 1.7
m. Age: Late Jurassic（150 million years ago） The fragment of Skull and the
partial bone are discovered. Since there are no less than
130 thin teeth at the tip of the beak on a spoon, it is
thought that a shrimp, small fish, etc. were filtered,
caught and eaten. ”Ceara
finger” Describer: Leonardi &
Borgomanero／ 1983 Distribution: Santana Formation, northeastern Brazil Pterodactyloidea／Pteranodontoidea／Cearadactylidae Skull length estimate= 57cm. Wingspan unknown Cearadactylus is a medium-sized
pterosaur. However, I do not have data in
addition to the partial fossil of a head. This pterosaur was discovered in
the KEARA state of Brazil. The direction put on
(Pterodactylinae) may say this pterosaur rather than it
seems that it had Beak with a random stake-like tooth
(Pteranodontoidea). It seems that it had preyed on
fishes from dental form. "Wing of the
South" Describer:
Jose Bonaparte／1970 Late Jurassic～Early Cretaceous PeriodWing
span 130ｃｍ The pterosaur discovered in
Argentina. the snout which curved upwards -- the thin tooth
which became like a mustache was located in a line with the
part Probably they are considered to have filtered water
through the tooth and to have eaten small fish, the
crustacea, an aquatic insect, etc. "Quetzalcoatl (feathered serpent

Late
Cretaceous／Texas
U.S.A Quetzalcoatlus was the largest
flying animal ever found. It had hollow bones, was lightly
built, and had a small body. Even though it was very big, it
probably weighed only about 135 kg . " old devil" Describer :Campos & Kellner /

long ／Cretaceous／Kansas
U.S.A It is the pterosaur considered that Nyctosaurus was
flying the ocean top in Kansas in Late Cretaceous. It is thought that Gracilis of TYPE SPECIE had a crest
more modest than the crest of Pteranodon, some data of the
fossil ofNyctosaurus like [ recently ] this image
is seen. This pterosaur with the too much wild crest is what thing
to be, although my imaginative power is
stimulated. "Junggar wing" Describer :Young / 1964 Pterodactyloidea／Plataleorhyncoidea／Dsungaripteridae Wing span 3.5m

Wingspan unknown/skull length 80cm/
Late Lower Cretaceous As for Tapejara, three kinds of
strange skulls of the shape are discovered but it is
wellnhoferi that is made a type specimen. However, it is this type that gives
the image which has unification most when I
picture. The display of the head
odd "gigantic bird hand" Describer :Seeley, 1869 Brazil, England Wingspan - up to 12 metres The fossil with fragmentary Ornithocheirus is discovered
in various parts of Europe. The kind also sets an unknown kind and goes up to a
considerable number. Giganteus is the largest in it. However, only the fossil with this kind of fragmentary
most is left behind.

Pterodactyloidea／Pteranodontoidea Species P. ingens (the type specis), P. eatoni, P. marshi, P. occidentalis, P. oregonensis, P. sternbergi, P. walkeri. Pteranodons lived during the late Cretaceous period and died out about 65 million years ago. They were flying pterosaurs that were about 1.8 m long, had 7.8 m wingspread, and weighed about 35 pounds． They had no teeth and they had large brains and good eyesight. Some pteranodons had long, light-weight, bony crests on their heads that may have acted as a rudder or stabilizer when flying, or may have been a sexual characteristic. They were carnivores. They ate fish , mollusks, crabs, insects, or scavenged dead animals on land. They may have hunted like modern-day pelicans, scooping fish out of the water and swallowing them whole when I imagine it from the shape of the bill of them .
