Dinosaurs are classified into the reptiles, and many did have scales. Current evidence suggests that Tyrannosaurus did have scales, but some have speculated that young tyrannosaurus may have had primitive feathers.
Pterodactylus fossils are best known from fossils found in the Solnhofen limestone of Bavaria, Germany. Fragmentary remains have been found in other parts of Europe as well as Africa, so their range would have included Europe and part of Africa.
The fossil record of early birds is very incomplete, because their bones are fragile and don't fossilize well. Since feathers don't fossilize very well either, no one really knows what these extinct birds looked like. Modern reconstructions are, therefore, based on educated guesses.
No dinosaurs had wings. You are thinking of Pterosaurs, the most famous being Pterodactylus and Pteranodon.
Edit: '''No dinosaurs had wings.''' That statement is wrong.
There are around 10,000 species of dinosaur alive today with wings, we call them birds. There are many fossils of maniraptorian dinosaurs that show wings.
The basal bird Archeopteryx, the dromeosaur Microraptor and the troodontid Anchiornis are some examples.
The famous Velociraptor had quill knobs on its ulna, which show that it too had ''wings''.
Wings in dinosaurs are only found in the theropod group, maniraptora.
If your thinking of pterosaurs like Pterodactylus and Pteranodon then those are not considered dinosaurs.
Pterosaurs were quadrupedal, using their wings not only to fly, but also to walk. This was also tha case for Pterodactylus. They were less than 1 ft tall when they walked, and they measured about 3 ft long.
The Jurassic is the second of the three periods of the Mesozoic. It was named for the Jura Mountains, where many of its fossils have been found.
Herbivores. The brontosaurus and brachiasaurus were herbivores.
Pterosaurs died out at the same time as the dinosaurs, during the K-T Extinction Event 65.5 million years ago. The most widely accepted theory is that an asteroid 6 miles in diameter crashed into the Yucatan Peninsula, leaving a crater that was 100 miles wide. Enough ash and dust was launched into the atmosphere that sunlight was blocked for months or even years. In that time, the plants all withered, and the animals that ate them starved. In turn, the pterosaurs, which would have fed on the small animals and fish that were disappearing, died out.
Pterodactylus was a small carnivore. While youngsters probably hunted insects, adults hunted small fish and land animals like lizards, amphibians, and primitive mammals.
Pterodactylus fossils date to between 150.8 to 148.5 million years ago. Thus, they presumably died out around 148.5 million years ago, during the Tithonian stage of the Jurassic period.
No. Pterodactyl was a pterosaur, and pterosaurs were technically not dinosaurs, though they are often incorrectly referred to as such.
Pteradactyl is actually scientifically named pterodactylus, despite the fact that not many people know this. Pterodactylus lived during the late Jurassic period. It had a long slender head and beak with small sharp teeth. Pterodactylus also had a short tail and webbed fingers.
Pteranodon was larger than the pterodactylus. It was tailless and lived during the cretaceous period. It had a long toothless beak, a bony crest and large wing span.
As is the main function of any bone, the main function of the bones in a pterosaur's fingers was to support the finger's structure. Pterosaurs had four fingers on each wing. Three of the fingers stuck out the front of the wing and were used for walking, as pterosaurs were quadrupedal. The extremely elongated fourth finger supported part of the front edge of the wing.
Like most pterosaurs, Pterodactylus probably didn't build nests. They buried their soft shelled eggs in sand, similar to modern crocodillians.
Most pterosaurs lived in coastal areas, near salt water. One major exception is Quetzalcoatlus, who lived near large rivers.
There are over 135 known genera of pterosaur, but none are known to have been plant eaters. All known pterosaurs were carnivores, and depending on the species, their diet would have consisted of insects, fish, or small land animals.
Pterodactylus was discovered in Bavaria, Germany. It was first described in 1784 by Cosimo Alessandro Collini, who believed it was an aquatic animal, simply because it looked so different from anything he had ever seen. In 1800, naturalist Johann Hermann figured out that Pterodactylus had wings and flew, and when he told Georges Cuvier, a zoologist, Cuvier determined that Pterodactylus was a reptile.
