yes
no, they are considered to be an actual type of reptile.
They are generally considered reptiles, though some think they should have their own class.
Zoologists who studies reptiles and amphibians are called Herpetologists
No, the majority of the scientific community has come to the conclusion that the dinosaurs were killed off by a meteor impact 65 million years ago.
i dont think there was any i mean scientist are starting to find things that look like dinosaurs but i think they all died in the meteor but like u can google it im not gonna stop you
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.
Most scientists believe that reptiles evolved from amphibians, specifically from ancient creatures known as early reptiliomorphs. These early tetrapods adapted to a more terrestrial lifestyle, eventually giving rise to reptiles.
A pterodactyl is technically not a dinosaur people just think it is. But, it certainly is a very very close relation to the dinosaurs, belong to a group of reptiles called pterosaurs. Even more closely related to dinosaurs are modern birds.
One reason is that there were a lot of fossils in many layers of rock and then suddenly, there are a lot fewer. Also, there don't appear to be many dinosaurs alive today. So, they went extinct. Do you really mean "how" did the dinosaurs go extinct?
Both. If you think about it, birds evolved from dinosaurs, and some think birds are the only living dinosaurs left.
i dont think its a
The first dinosaur's appeared on earth at about 230 million years ago. the first dinosaur was called Eoraptorc, found in Argentina and Brazil. It was a small meat eating creature. Scientist think there may be older dinosaurs out there.
