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.
Why are pterosaurs not classified as dinosaurs?
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.
Why are pterosaurs and mosasaurs not dinosaurs?
Pterosaurs were members of a group called “Archosaurs” which also includes dinosaurs and crocodiles, so they're a distant relative of dinosaurs. Mosasaurs, meanwhile, were actually giant lizards, close relatives of the monitor lizards of today, including Komodo Dragons.
What is the difference between a pterodactyl and a pterosaur?
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.
Are pterosaurs sister group to dinosaurs?
With the help of pterosaur skulls and skeletons that were unearthed in North America, Brazil, Argentina, and Madagascar in recent years, a team of paleontologists has now demonstrated that flightless dinosaur precursors called lagerpetids (family Lagerpetidae) are the sister group of pterosaurs.
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 dinosaur is technically not a dinosaur?
Marine reptiles, such as ichthyosaurs, plesiosaurs and mosasaurs are not dinosaurs. Nor is Dimetrodon or other reptiles in the same group (previously called 'mammal-like reptiles' and now called synapsids). None of these other extinct groups shared the characteristic upright stance of dinosaurs.
What is the name of a flying dinosaur?
Pterodactyl Pterodactyl is the common term for the winged reptiles properly called pterosaurs, which belong to the taxonomic order Pterosauria, according to McGill University.
