Theropods, a type of bipedal, carnivorous dinosaur.
Answer:Possibly none. Birds may have evolved from a creature, likely a reptile, that pre-dated the dinosaurs. Birds do have many features in common with theropods (bipedal carnivorous dinosaurs) which suggests that they had a common ancestor. We dont know that this common ancestor was a dinosaur though. It may well have been a bird (see related links).Looking back in time through the theropod fossil record, these dinosaurs appear to be more bird-like the further back in time you look. Raptors are known to have had feathers and were fairly bird-like, but Archaeopteryx was much more bird-like and lived much earlier and may have been an ancestor of the raptors. There is also a controversial fossil called Protoavis that was dated even earlier and was more bird-like still, with hollow bones like modern birds.
So birds may have been around throughout the mesozoic era and pre-date the dinosaurs. We have little record of them though because their more fragile, hollow bones reduce the chances of any fossils surviving to the present day.
What else can I help you with?
Why do scientists believe that birds evolved from dinosaurs?
Scientists believe birds evolved from dinosaurs because of several pieces of evidence, such as shared skeletal features, fossil records of "transitional" bird-like dinosaurs, and genetic similarities. These connections suggest that birds are the descendants of a group of small theropod dinosaurs.
Names of dinosaurs that survived extinction?
No dinosaur species survived the mass extinction event that occurred at the end of the Cretaceous period about 66 million years ago. However, birds are considered descendants of theropod dinosaurs and are the only living group of dinosaurs today.
What are the living ancestors of dinosaurs?
Birds are considered the living ancestors of dinosaurs. Modern birds evolved from a group of two-legged dinosaurs known as theropods, which also included the iconic Tyrannosaurus rex and Velociraptor. Birds share many similar traits with their dinosaur ancestors, such as hollow bones and feathers.
Did dinosaurs evolve into birds before or after a meteor killed all the dinosaurs?
Birds evolved in the late Jurassic Period about 150 to 145 million years ago. This was about 90 to 95 million years before the asteroid impact that marked the K-T extinction event.Just a sub note that most scientist recognise that birds are a specialised branch of the therapod dinosaur. Birds are dinosaurs in the same way cats are mammals.
What did Birds evolved from?
Birds are believed to have evolved from theropod dinosaurs during the Mesozoic era. The fossil record shows a gradual transition from small, feathered dinosaurs to early bird species, which eventually led to the wide diversity of bird species we see today.
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 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."
Did dinosaurs evolve into reptiles?
No. Dinosaurs evolved from reptiles. Birds evolved from 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.
Did birds ever evolve to dinosaurs?
No. It's the other way around. A branch of the dinosaurs evolved into birds.
Did mammals evolve from a group of reptiles called raptors?
No. Mammals evolved from a group of reptiles called cynodonts. "Raptor" is an informal term for a group of dinosaurs call dromaeosaurids, which were closely related to the ancestors of birds.
What major group of vertebrates evolved from dinosaurs?
Birds
What order of dinosaurs did birds evolve from?
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.
How do birds and dinosaurs relate?
Birds branched of from a group of dinosaurs called theropods (the two legged dinosaurs consisting mostly of carnivores) in the late Jurassic period.
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.
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.
