Did dinosaurs evolve from lizards?
No. Lizards and snakes came from different branches of reptiles. Dionosaurs evolved from archosaurs while lizards evolved from lepidosaurs.
What is mostly related to crocodiles rodents or birds?
Birds. The reason is that both crocodiles and dinosaurs are archosaurs, and birds evolved from dinosaurs.
Is there an animal closely related to a bird?
Birds evolved from non-avian theropod dinosaurs. Because all non-avian dinosaurs are extinct, the closest living relatives of birds are crocodillians. Crocodillians and birds are the last surviving archosaurs. Two extinct archosaurs are dinosaurs and pterosaurs.
What is the pterodactyl evolution?
Pterodactylus was a pterosaur, and pterosaurs were archosaurs. All pterosaurs died out 65.5 million years ago. Other types of archosaurs include crocodillians, the dinosaurs, and the birds, which evolved from dinosaurs. The pterosaurs were more closely related to the dinosaurs than they were to crocodillians, so the closest living relatives of pterosaurs are the birds. All birds are equally related to pterosaurs.
Why do we think birds Evolved from crocodiles and alligators?
They didn't but they do share a common ancestor. Looking at fossils, scientists have determined that bird evolved from small carnivorous dinosaurs. Both dinosaurs and crocodiles stem from a group of reptiles called archosaurs.
Did dinosaurs evolve from reptiles?
Dinosaurs evolved from reptiles not the other way around. The first reptiles where thought to have evolved during the late Carboniferous Period about 320 to 310 million years ago. Dinosaurs do not appear in the fossil record until the late Jurassic Period about 230 million years ago. They evolved from the reptilian infra class Archosaurs.
Why were dinosaurs created?
The dinosaurs existed as they evolved best to fit the ecological niches of the day.
Are hawks more closely related to a bat a shark or an alligator.?
In terms of evolution, hawks are most closely related to alligators. This is because birds evolved from dinosaurs and both alligators and dinosaurs are archosaurs.
What other modern day species are the pterodactyl's related to?
Pterodactylus was a pterosaur, and pterosaurs were archosaurs. All pterosaurs died out 65.5 million years ago. Other types of archosaurs include crocodillians, the dinosaurs, and the birds, which evolved from dinosaurs. The pterosaurs were more closely related to the dinosaurs than they were to crocodillians, so the closest living relatives of pterosaurs are the birds. All birds are equally related to pterosaurs.
Mammals and birds are descended from what group of vertebrates?
Mammals and birds are both descended from a group of vertebrates known as archosaurs. This group included early reptiles and gave rise to both dinosaurs (which birds evolved from) and the ancestors of mammals.
Is the Crocodile really a descendant of the dinosaur?
Crocodilians are distantly related to the dinosaurs in that they are both Archosaurs, but the former definitely are not descended from the Dinosaurs. They are both members of what is known as a ''crown group'' (the Archosauria). This refers back to a long-extinct bevy of Reptiles that includes the common ancestor of the two living archosaurs -- crocodilians and birds -- and the extinct avian and non-avian dinosaurs. In short, they are related only in that they (crocodilians and dinosaurs) both evolved from the same ancestral reptile.
What are dinosaurs in general?
A special type of reptiles called "Archosaurs."
