There has been research done that indicates that birds have evolved from dinosaurs. and mounting evidence shows that theropod dinosaurs are the ancestors of birds. Evidence includes countless skeletal similarities and evidence of feathers in many fossils. Feathers were thought to originally developed for warmth, and eventually evolved into flight aids.
In face of this many scientists do consider birds to be descended from dinosaurs, if not a branch of them.
Answer: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 even pre-date the dinosaurs. We have little record of them though because their hollow bones decompose very easily so are less likely to leave fossils. We do have some very ancient bird footprints though (see 3rd link).
It may be more accurate to call the theropods Flightless Birds, rather than calling birds dinosaurs.

∙ 11y agoNot all dinosaurs were birds. However, birds did evolve from theropod dinosaurs. Therefor, birds are considered a group of dinosaurs, the avian dinosaurs.
We don't know for sure that birds evolved from dinosaurs. though evidence is very strong.

Why do birds not have teeth if they are a form of dinosaur?
Because certain dinosaurs had teeth. First off all dinosaurs had teeth, if not tel me one that didn`t, and dinosaurs are birds and reptiles, not just birds.
Why do scientists believe that birds evolved from dinosaurs?
Birds are thought to have evolved from bipedal dinosaurs.
What did Birds evolved from?
The general consensus is that they evolved from a group of small theropod dinosaurs.
Are turkeys dinosaurs?
No. Turtle are from a branch of reptiles completely separate from dinosaurs.
Most scientists now believe that birds evolved directly from bipedal?
Most scientists believe that birds evolved directly from bipedal, terrestrial dinosaurs.
Are dinosaur birds mammals?
Birds are now classed as dinosaurs, but most dinosaurs were not birds. Neither dinosaurs nor birds are mammals.
Which animal was alive first birds or dinosaurs?
Dinosaurs evolved first and then some dinosaurs evolved into birds. So all birds are technically dinosaurs.
Were dinosaurs or birds the first beings?
Dinosaurs came before birds, because dinosaurs later on evolved into birds, therefore, making birds come along LATER then the dinosaurs. However dinosaurs were far from the first creatures on earth.
What was around longer birds or dinosaurs?
Both. If you think about it, birds evolved from dinosaurs, and some think birds are the only living dinosaurs left.
Were normal birds alive during the Dinosaur times?
birds are dinosaurs some birds that lived with dinosaurs were archeopteryx, confuisosornis, and avivisaurus these creatures are dinosaurs all birds were dinosaurs
Are cassowary birds related to dinosaurs?
Yes. All birds are direct descendants of dinosaurs and are considered by many to be dinosaurs.
Birds are direct descedants of the dinosaurs?
they are dinosaurs
What are dinosaurs most closely related to?
Dinosaurs are most closely related to birds to the extent that birds are cnsidered a branch of dinosaurs.
Are there still living dinosaurs?
yes crocodiles and alligators are dinosaurs and some dinosaurs turned into birds
Are people sure dinosaurs are still alive?
Birds are dinosaurs and today everywhere we have birds.
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.
