Many scientists claim that birds evolved from theropod dinosaurs over 100 million years ago.  The most-frequently claimed candidate for a [[transitional form]] is ''[[Archaeopteryx|Archaeopteryx lithographica]]'' which is from the late [[Jurassic]] (about 150 million years ago) of [[Germany]].

A very widely held hypothesis is that birds evolved from theropod dinosaurs over 100 million years ago.  The most-frequently claimed candidate for a [[transitional form]] is ''[[Archaeopteryx|Archaeopteryx lithographica]]'' which is from the late [[Jurassic]] (about 150 million years ago) of [[Germany]].

There are other claimed transitional fossils <ref>http://www.talkorigins.org/faqs/faq-transitional/part1b.html#bird</ref> also.

There are many papers in the peer-reviewed science journals such as ''Nature'' and ''Science'' that support the idea that birds evolved from dinosaurs.  For example:

There are many papers in the peer-reviewed science literature, including leading journals such as ''Nature'' and ''Science'', that support the idea that birds are a sub-group of dinosaurs.  For example:

{{QuoteBox|Several features, including a carinate sternum and reduced fibula, suggest that ''Mononychus olecranus'' is more closely related to modern birds than is ''Archaeopteryx lithographica''. The two skeletons are among the best preserved fossils known of a primitive bird, and emphasize the complexity of the morphological transformation from nonavialian theropods to modern birds. The occurrence of such a primitive bird in the Late Cretaceous reflects the paucity of Mesozoic bird fossils and suggests that the early radiation of avialians is only beginning to be sampled

Almost all evolutionary biologists, with rare exceptions, believe that birds are the only extant group of dinosaurs, a branch of the theropods, which included ''Velociraptor'' and ''Deinonychus''. This view is disputed by [[creationism|creationists]], and also by a few prominent evolutionists, including Storrs L. Olson, Curator of Birds at the [[National Museum of Natural History]] at the [[Smithsonian Institution]], who said: {{QuoteBox|The idea of feathered dinosaurs and the theropod origin of birds is being actively promulgated by a cadre of zealous scientists acting in concert with certain editors at Nature and National Geographic who themselves have become outspoken and highly biased proselytizers of the faith.
