Had a hip structure similar to birds?
Ornithischians with a hip structure similar to that of present day birds.
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
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.
Is big al similar to a bird and a reptile?
Yes, Big Al is similar to both birds and reptiles in that it is a type of dinosaur. Birds are believed to have evolved from certain types of dinosaurs, and reptiles are part of the same broader group of animals that includes dinosaurs. Big Al specifically belongs to the group of dinosaurs known as theropods, which are closely related to both birds and some reptiles.
What had a hip structure similar to birds?
Theropod dinosaurs for one.
Are dinosaurs birds or lizards?
The answer to you question both Yes and No ... Dinosaurs are the evolutionary ancestors of both lizards and birds but they, themselves were neither lizards or birds. They were a separate, distinct breed of beast. all to themselves
Both and birds and dinosaurs have amniotic eggs?
Yes
Why do some scientist believe that dinosaurs were the primogenitors of the modern birds?
Scientists have found a number of fossils of theropod dinosaurs with anatomy remarkably similar to that of birds. Many dinosaurs are now known to have had feathers.
What made scientists think birds and reptiles were related?
Scientist think that birds are related to dinosaurs because as you study the fossilised bones of certain therapod dinosaurs especially dromaeosaurs you start to notice many similarities between them and modern day birds. The famous archeopteryx for example, which is historically considered the first bird, looked very much like a bird but still had claws on its wings and had a mouth full of teeth. Other dinosaurs from the same time period look even more like birds. In fact experiments done on modern day bird embryos show that if you play around with the genes of birds you can engineer dinosaur features such as teeth, long dinosaur tails etc. All the key features that people associate with birds developed when they were still dinosaurs. Dinosaurs had feathers, dinosaurs had oval shaped eggs, dinosaurs had beaks. The morphology of birds is so similar to some dinosaurs that scientist are starting to consider birds as not just related to dinosaurs but actually as avian dinosaurs.
Why do reptiles and birds have so much in common?
The most similar thing about birds and reptiles is that they both lay eggs. However, it is important to note that not all reptiles lay eggs. There are many species of snakes and lizards which do not lay eggs, but instead give birth to live young.
Are hens 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.
