Birds evolved from a group of Saurischian dinosaurs known as theropods. The theropods include dinosaurs such as Tyrannosaurus, Velociraptor, and Deinonychus. Theropods were predators who walked on two feet and had relatively small arms. Some of these dinosaurs were small and started growing feathers, at first to keep warm. Eventually these feathers became adapted for flying.
What else can I help you with?
Did dinosaurs evolve into reptiles?
No. Dinosaurs evolved from reptiles. Birds evolved from dinosaurs.
Did birds evolve from lizards?
No, birds didn't evolve from lizards, but they did evolve from dinosaurs, a different group of reptiles. Dinosaurs are different from lizards especially because of their hip structure. Birds descended from a group of dinosaurs known as theropods (bipedal carnivores)
Did birds ever evolve to dinosaurs?
No. It's the other way around. A branch of the dinosaurs evolved into birds.
Did underwater dinosaurs evolve into crocodiles?
what an interesting topic! Birds and reptiles are the living descendantsof the dinosaurs that survived the meteorite-triggered mass extinction that killed off most of the species living 66 million years ago. And of all reptiles, crocodiles are the most closely related to birds.
Did birds evolve from the gliding called pterosaurs?
No. Birds evolved from a group of small carnivorous dinosaurs related to the "raptors."
Does the wolf eat dinosaurs?
Wolves didn't evolve until long after the extinction of non-avian dinosaurs. However, birds are considered dinosaurs, and wolves do sometimes eat birds, so I would say that wolves do eat dinosaurs.
Why have dinosaurs not changes since before the time of dinosaurs?
Dinosaurs are extinct, buddy. I don't know what planet you live on, but they've been gone for a long time. And they did evolve, they turned into birds and mammals. Robert, they likely did not evolve into mammals, the mammals were already there. Although, I will give you credit on birds, due to the Archaeopteryx.
How did birds evolve from reptiles?
But they did. Specifically, birds evolved from a subgroup of dinosaurs (which were reptiles) known as theropods. There is a lot of fossil and anatomical evidence for this.
Where manaties with dinosaurs?
The non avian dinosaurs became extinct 65.5 million years ago. The earliest sirenians, (the order that includes manatees), didn't evolve until about 50 million years ago, 15 million years after the extinction of the non avian dinosaurs. However, scientists consider birds a group of dinosaurs, and, because birds still exist today, manatees do coexist with avian dinosaurs.
Did mammals evolve from 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.
Are parrots in the time when dinosaurs were alive?
In the sense that birds are dinosaurs, and thus that dinosaurs are still alive, yes. However they were not alive when non-avian dinosaurs were around. Parrots did not evolve until a few million years after non-avian dinosaurs died out.
Are dinosaur birds mammals?
Birds are now classed as dinosaurs, but most dinosaurs were not birds. Neither dinosaurs nor birds are mammals.
