Many dinosaurs have birdlike traits. The basic body plan of theropods (the two legged carnivores) is somewhat birdlike. However some of these are especially birdlike. Among these are Archeopteryx, which is widely attributed to be the earliest known bird and clearly has traits of maniraptoran theropods. A number of maniraptorans such as Velociraptor are now known to have had large, well-developed feathers. One relative, Microraptor, is believed to have been able to glide between trees.

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.
What animal do scientists think penguins evolved from?
Penguins evolved from birds. :)
Why do we think birds Evolved from crocodiles and alligators?
They didn't but they do share a common ancestor. Looking at fossils, scientists have determined that bird evolved from small carnivorous dinosaurs. Both dinosaurs and crocodiles stem from a group of reptiles called archosaurs.
Why do scientists think that dinosasurs evolved into birds?
90% of modern birds
Do dinosaurs still live to this day?
Dinosaurs as most people think of them are completely extinct. However, birds evolved from dinosaurs, and as such, are considered to be a group of dinosaurs. Since birds are still alive today, so are some dinosaurs. No dinosaurs other than birds are alive today, though.
Why do scientists think that some dinosaurs are like today's birds?
becuase of simalarities
Are dinosaurs stiil about?
Technically yes. Birds are evolved dinosaurs. Animals traditionally thought of as dinosaurs; Tyrannosaurus, Triceratops, Baryonyx, ect; are extinct. I think some turtles and gators where around back then also.
How long have any type of birds been on this earth?
In a scientific view, birds first evolved from reptiles during the Jurrasic period (200-145 million years ago). One of the earlist birds was Archaeopteryx, whos name means "ancient bird'. However, on a religious point of view, birds were created by God on day 4.
Did people hunt dinosaurs?
Not dinosaurs as we traditionally think of them. "Classic" dinosaurs went extinict long before any people were around. However, scientists now know that one group of dinosaurs lives to this day: birds. Birds of various types have long been hunted by humans.
Do dinosaurs have 2 tongues?
I don't think scientists have ever found a fossilized dinosaur tongue. However, there is no reason to believe they would have had two tongues, since no modern animals do. Additionally, birds evolved from dinosaurs and they only have one tongue, and it's not even forked. So, it's safe to say dinosaurs had a single, non-forked tongue.
What observations did scientists make about dinosaurs that made them think dinosaurs were not l izards?
-Dinosaurs have thin/hollow bones, like birds. -Many dinosaurs take care of their young. -Dinosaurs can walk upright (some, at least). -The hip structure of dinosaurs is dissimilar to that of a lizard.
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.
