It is generally believed that birds evolved from small, feathered, meat eating dinosaur during the Jurassic period. This is because of the similarities between those dinosaurs and early birds, which include feathers, 'hollow' bones (really they have an internal honeycomb structure), beaks, and other similar features. Additionally, animals that appear to be evolutionary links between birds and dinosaurs exist, such as Archaeopteryx.
Yes there is. Birds are directly descended from a group of small carnivorous dinosaurs that lived in the Jurassic period.
they have the same bones and some had feathers
Birds have an evolutionary link between Dinosaurs...
Yes (WITH A BIG MAYBE ATTACHED) The difference between certain therapod dinosaurs and birds is very small. Every feature we use to describe birds (beak, feathers, wings) first evolved on dinosaurs. In fact the morphology between birds and the raptor family of therapod dinosaurs is so similar many scientists to call birds avian dinosaurs.
Birds are now classed as dinosaurs, but most dinosaurs were not birds. Neither dinosaurs nor birds are mammals.
Dinosaurs evolved first and then some dinosaurs evolved into birds. So all birds are technically dinosaurs.
Not a whole lot. Birds and dinosaurs share the same skeletal structure and walk the same and many had feathers and were probably warm blooded.
Pterosaurs were closely related to the dinosaurs. Because birds have descended from dinosaurs, the closest living relatives of pterosaurs are birds. All birds are equally related to pterosaurs.
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.
Both. If you think about it, birds evolved from dinosaurs, and some think birds are the only living dinosaurs left.
birds are dinosaurs some birds that lived with dinosaurs were archeopteryx, confuisosornis, and avivisaurus these creatures are dinosaurs all birds were dinosaurs
Otherwise known as dino birds, these dinos were the first "birds" to exist.
Yes. All birds are direct descendants of dinosaurs and are considered by many to be dinosaurs.
