What traits are shared by the archaeopteryx and moderrn birds?
Archaeopteryx had three main features that modern birds do not. First, they had a toothed beak. Second, they had three fingers on the front fringe of the wing. Third, they had a long bony tail.
What is the first bird?
Archaeopteryx is the earliest undisputed bird. A weak flyer, it shared characteristics with its dinosaur ancestors. Fossils show that Archaeopteryx , like dinosaurs, had teeth, a long bony tail, and grasping claws on its wings, but also had a bird-style hip and feathers.
Is archaeopteryx a swift runner?
Yes. Identified by many as the first bird, Archaeopteryx resembles a coelurosaur but was covered in feathers. (Its remains were found in fine grained stone which still bore the clear impression of its feathers.) Archaeopteryx was 3 feet (0.9 meters) long with sharp teeth, a long bony tail, and claw fingers on its wings. The only known member of this family was discovered in Bavaria, Germany. There is considerable debate whether Archaeopteryx and Mononychus should be classified as dinosaurs.
Which features of the archaeopteryx could be described as reptilian?
Archaeopteryx had claws on its wings, a long tail, and a toothed beak. These are all considered reptilian traits.
What are two basic groups of pterosaurs?
The Pterosauria order was divided into two suborders. The first was the Rhamphorhynchoidea, which had teeth and long tails, and didn't have bony crests. The second was the Pterodactyloidea, and they had very short tails, many types were toothless, and many types did have elaborate bony crests. The Pterodactyloidea evolved from the Rhamphorhynchoidea during the Jurassic, so technically most scientists consider Pterodactyloidea to be a subgroup of Rhamphorhynchoidea.
Why is an archaeopteryx hard to classify?
Archaeopteryx is considered difficult to classify because it possesses characteristics of both dinosaurs and birds. Its fossils show features like wings and feathers, common in birds, but also traits like teeth and a long bony tail seen in dinosaurs. This mixture of attributes makes its classification a topic of debate among scientists.
