A evolutionary form of a bird. It had wings and feathers but still probably acted like a dinosaur but im not sure.
Archaeopteryx is a genus of bird-like dinosaur that lived during the Late Jurassic period. It is considered a transitional species between non-avian dinosaurs and modern birds due to its combination of dinosaurian and avian traits. Fossils of Archaeopteryx have provided important evidence for the evolutionary link between dinosaurs and birds.
There is no direct evidence to suggest that Archaeopteryx hunted in groups. Based on its anatomy and behavior, it is more likely that Archaeopteryx was a solitary hunter, similar to modern birds of prey.
Yes, but not very closely. Specifically, crocodiles and Liopleurodon are diapsid reptiles, but that is a very large grouping of animals indeed. To illustrate, crocodiles are more closely related to chickens than they are to Liopleurodon, on account of chickens being archosaurs, just as crocodiles are. Liopleurodon belongs to the pliosaurs, a group of extinct marine reptiles with relatively short necks. They are thought to be more closely related to lizards and snakes than to crocodiles. The external similarities between Liopleurodon and crocodiles (that long snout with a multitude of sharp teeth, for example) are due to convergent evolution, not a close evolutionary relationship. However, there did exist "marine crocodiles" that lived at about the same time as pliosaurs like Liopleurodon that were much more closely related to modern crocodiles, i.e. Thalattosuchians.
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.
Theropods - Allosaurus - Sinornis - Velociraptor - Archaeopteryx
Archaeopteryx is not believed to be an ancestor to any modern animals. However, it was probably closely related to the evolutionary link between birds and dinosaurs.
No. Mammals evolved from synapsid reptiles, a group not closely related to dinosaurs. Dinosaurs are more closely related to modern reptiles and birds than they are to mammals.
Not at all. Giraffes are mammals, which are not closely related to dinosaurs. Dinosaurs are more closely related to birds and modern reptiles.
Archaeopteryx is considered the 1st Bird. It was from a long line of Avian dinosaurs which are very very closely related to the Raptor family of Therapod Dinosaurs. The morphology of avian dinosaurs and modern birds are so similar many scientist class birds as avian dinosaurs.
They are generally considered reptiles, though some think they should have their own class.
Birds and reptiles.
No. Dinosaurs were not mammals. They were more closely related to birds and modern reptiles than they were to mammals.
No. Lizards evolved from a separate group of reptiles and, as far as reptiles go, are not closely related to dinosaurs. The modern "evolved form" of the dinosaurs is actually the birds.
Dinosaurs and mammals evolved from two separate branches of reptiles. Mammals evolved from synapisid reptiles (all of which are not extinct) while dinosaurs along with the modern branches of reptiles evolved from sauropsids. So dinosaurs are more closely related to modern reptiles than they are to mammals. In more recent years scientist tend to agree that birds are in fact a surviving branch of dinosaurs.
Yes, In fact, experts believe that Dinosaurs are more closely related to Birds than modern-day reptiles. Before Dinosaurs died out, some evolved into Birds. When the disaster struck that wiped out the Dinosaurs, the Birds survived. You can see how closely related Dinosaurs and Birds are by comparing a Compsognathus (small Dinosaur) skeleton to an Archaeopteryx (early prehistoric bird) skeleton, and you will notice that they are very similar.
A pterodactyl is technically not a dinosaur people just think it is. But, it certainly is a very very close relation to the dinosaurs, belong to a group of reptiles called pterosaurs. Even more closely related to dinosaurs are modern birds.
Ultimately all organisms are related. Humans are mammals, which are not closely related to reptiles. Mammals and reptiles belong to a group of animals called amniotes, which they also share with birds. Amniotes include all land vertebrates except amphibians. The last common ancestor of mammals and reptiles lived over 300 million years ago in the Carboniferous period. Shortly after the first amniotes branched off from amphibians they split into synapsids, which became the ancestors of mammals, and sauropsids, which became the ancestors of birds and all modern reptiles.
