Difference Between Pterodactyl and Pteranodon

Thekey differencebetweenPterodactyl和Pteranodonis thatPterodactyl是一个genusthat includeswinged reptiles with teeth, whilePteranodon是一个genusthat includeswinged reptiles without teeth

Pterodactyl和Pteranodonare two genera of Pterosaur. Pterosaur includes flying reptiles of the extinct clade Pterosauria. They existed in the Mesozoic era, most probably from the late Triassic to the end of the Cretaceous periods, approximately 228 to 66 million years ago. Pterosaurs were capable of aerial locomotion by powered flight. Their wings were made by the membrane of skin, muscles and other tissues. Pterosaurs are often referred to as “flying dinosaurs” by popular media though they are not恐龙. Furthermore, Pterosaurs had different lifestyles. Most of them were fish eaters, and they reproduced through eggs.

What isPterodactyl?

Pterodactyl是翼龙的属，包括带有牙齿的翅膀爬行动物。它是翼龙的灭绝属。它仅包含一个物种：Pterodactyl usantiquus. This species was the first Pterosaurs to be named and identified as flying reptiles.Fossils of this genuswere found in the Solnhofen limestone of Bavaria, Germany. These fossil remains date back to the late Jurassic period, about 150.8 to 148.5 million years. Moreover, it was found that they were carnivores and fed on a variety ofinvertebrates and vertebrates.

Based on fossil remain evidence,Pterodactyl usantiquus是一个相对较小的翼龙，估计成年翼展为1.04米。他们的成年头骨长，薄，有90个狭窄的圆锥形牙齿。Pterodactyl就像它们相关的翼龙一样，其头骨上的冠峰主要由软组织组成。Pterodactylgrowth pattern is very similar to modern crocodiles rather than birds. They most likely walked on four legs when they were on land. Further, based on the size, shape, and arrangement of teeth,Pterodactyl被认为是食肉动物的食肉动物。

What isPteranodon?

Pteranodon是一个genus of Pterosaur that included winged reptiles without teeth. They were some of the largest known flying reptiles of Pterosaurs. They lived during the late Cretaceous geological period. Their fossils were found in present-day North America: Kansas, Alabama, Nebraska, Wyoming, and South Dakota. Additionally, the fossil remains ofPteranodonhave been found than any other pterosaur, with about 1,200 specimens.

Pteranodon标本可以分为两个不同的尺寸类。较小的级别具有小的，圆形的头顶和非常宽的骨盆运河。较小的类别代表成年女性。因此，更宽的骨盆运河可能使它们产卵。较大的尺寸类代表雄性，臀部狭窄，顶rest非常大。Pteranodonhad toothless beaks, which is very similar to birds. The most distinct feature is their cranial crest that consisted of skull bones. It projects upwards and backwards from the skull. The size and shape of the crest vary due to a number of factors such as age, sex, and species.Pteranodonwingspan is over 7 meters. The diet ofPteranodonmainly consisted of fish.

两者都不Pterodactyl也不Pteranodon有羽毛。

What is the Difference BetweenPterodactyl和Pteranodon?

Pterodactyl是一个genus that includes winged reptiles with teeth. On the other hand,Pteranodon是一个属，包括没有牙齿的有翼爬行动物。因此，这是Pterodactyl和Pteranodon. Moreover,Pterodactyl生活在中生代的侏罗纪后期，而Pteranodonlived in the late Cretaceous period of the Mesozoic era.

Summary –PterodactylvsPteranodon

Pterosaurs are winged reptiles that became extinct 66 million years ago. They used to live in the Mesozoic, era most probably from the late Triassic to the end of the Cretaceous periods. There are at least 130 valid pterosaur genera.Pterodactyl和Pteranodonare two genera of Pterosaur.Pterodactylgenus consisted of winged reptiles with teeth.Pteranodon属由无牙的有翼爬行动物组成。因此，这是Pterodactyl和Pteranodon.
