What kind of dinosaur is a pterosaur?
Neither birds nor bats, pterosaurs were reptiles, close cousins of dinosaurs who evolved on a separate branch of the reptile family tree. They were also the first animals after insects to evolve powered flight—not just leaping or gliding, but flapping their wings to generate lift and travel through the air.
What is the difference between a dinosaur and a pterosaur?
Because they flew and their front limbs stretch out to the sides, they are not dinosaurs. Instead, they’re a distant dinosaur cousin. Pterosaurs lived from the late Triassic Period to the end of the Cretaceous Period, when they went extinct along with dinosaurs. Like birds, pterosaurs had lightweight, hollow bones.
What is the difference between a pterosaur and a pterodactyl?
Pterodactyl, or Pterodactylus antiquus, is actually a specific type of pterosaur in the group Pterosauria, which encompasses the entire group of prehistoric flying reptiles. Pterodactylus antiquus lived 150 million years ago, ate insects or fish, and had wingspans of up to five feet.
What is pterodactyl look like?
In art, the pterodactyl is usually portrayed with bat-like wings, the membranes of which are stretched taut between its elongated fingers. It is also frequently shown with a crest on its head, although there is some debate as to whether this crest was extant in the Pterodactyl as with other Pterosaurs.
Did birds evolve from pterosaurs?
The Pterosaurs and pterodactyls were once considered ancestors of birds, and there are certain similarities such as pneumatic bones, but the pterosaurs had a wing membrane like bats and no feathers. Birds evolved from a group of small bipedal dinosaurs.
How many pterosaurs are there?
There are around 110 species of pterosaur currently known in about 85 genera.
What is the largest pterosaur?
Pterosaurs with largest wingspan
- Santanadactylus araripensis 5.7 m (19 ft)
- Cearadactylus atrox 5.5 m (18 ft)
- Caulkicephalus trimicrodon 5 m (16 ft)
- Istiodactylus latidens 5 m (16 ft)

Why did pterosaurs go extinct?
At the end of the Cretaceous period 65 million years ago, a meteorite or comet slammed into Earth. That calamity—and other events—wiped out roughly three-quarters of all animal species, including all remaining pterosaurs and dinosaurs.
Why is a pterosaur not considered a dinosaur?
So, as things stand now, pterosaurs are not dinosaurs by virtue of descent: they are not believed to have descended from the most recent common ancestor of Passer and Triceratops. This has been determined, to the best ability given currently-known fossils, by the lack of a number of truly dinosaurian features, primarily those with respect to the structure of the hip.
What does the dinosaur name pterosaurs mean?
Pterosaurs (/ ˈ t ɛr ə s ɔːr, ˈ t ɛr oʊ-/; from Greek pteron and sauros, meaning “wing lizard”) were flying reptiles of the extinct clade or order Pterosauria.They existed during most of the Mesozoic: from the late Triassic to the end of the Cretaceous (228 to 66 million years ago).Pterosaurs are the earliest vertebrates known to have evolved powered flight.
Is a pterosaur a reptile?
Quetzalcoatlus is a pterosaur. Pterosaurs are reptiles, but they are not dinosaurs. They’re not lizards or crocodilians , either. They are a separate branch of the reptile evolutionary tree, closely related to dinosaurs.
What was the average size of a pterodactyl dinosaur?
The Pterodactyl was part of a group of dinosaurs known as Pterosaur (wing lizard). They lived at the end of the Jurassic Period between 148 and 151 million years ago. Estimates put the average length of a Pterodactyl at 3.5 feet. Estimates put the weight of the Pterodactyl between 2 and 10 pounds.
