you wouldn't! no body knew about them until people starting finding mysteriously large bones all around the world and finally scientists figured it out.
you wouldn't there would no for sure way and even the fossils could be another species than what we thought. No one can really be able to tell what happened years ago even with fossils. There is stil no for certain way.
Fossils affect how people think about ancient creatures of Earth. The fossils show animals that people did not previously know existed.
Depends on the type of eurypterid. In short, no; we don't know enough about them to say that they are only found in certain time zones.
Certainly fossilized parts of dinosaurs had been found for centuries but people didn't know exactly what they were. They were mistaken for all sorts of animals. I think it was Othniel Charles Marsh in the mid-to-late 19th century who first systematically collected dinosaur fossils and assembled them so that it became clear what they were and how they were related.
Scientists know that dinosaurs existed back then because all of the fossils that they found and tested dated back between 64 and 65 millon years ago. They also have a theory that a massive asteroid hit the earth and that is what they think killed all of the dinosaurs but nobody knows for definite.
Humans are not index fossils because human remains are only found in very recent unlithified deposits up to the present, which we would usually already know to be very recent.
Because they are alive today, birds are dinosaurs. And because of fossils.
When a dino dies, it becomes a fossil. We know that the dinosaurs existed because they left behind fossils we see today.
Dinosaur fossils prove that they existed. I personally know about them by reading about them and watching documentaries about them.
I know about dinosaurs from reading about them, watching documentaries, and a visit to a natural history museum to see dinosaur fossils in person. Scientists learned about dinosaurs by studying fossils, including bones, skin impressions, and footprints, and the rocks the fossils were found in.
I know about dinosaurs and their habitats from reading about them. Scientists learn about dinosaurs and their habitats by studying fossils.
Our most provident evidence would be carbon dating and fossils.
as far as I know, Yes Dinosaurs did existed
Fossils
From the fossils and where they are found.Mr. Seidschlag
Dinosaurs are reconstructed from fossils, petrified remains, trace fossils, and comparisons with existing animals.
by the process of dating fossils
The fossils of their shells, etc.
