Because they are alive today, birds are dinosaurs.
And because of fossils.
as far as I know, Yes Dinosaurs did existed
they are not sure how they died out
Dinosaur fossils prove that they existed. I personally know about them by reading about them and watching documentaries about them.
Dinosaurs are not mythical they lived hundreds,and hundreds,and hundreds of years ago
so they can know how there body and bones were
When a dino dies, it becomes a fossil. We know that the dinosaurs existed because they left behind fossils we see today.
A scientist who studies dinosaurs is called a paleontologist.
Palentologist lol I know its spelled wrong
existed. as in, "dinosaurs existed on this world years ago"
We do not know the total number of dinosaurs that existed, as many have not been discovered. Currently, there are 500 known genera and 1,000 different species.
Yes. Worms existed long before dinosaurs did.
people and dinosaurs never co-existed
