Are dinosaurs Real in 2020?

Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive. These, and all other non-avian dinosaurs became extinct at least 65 million years ago at the end of the Cretaceous Period.

Did dinosaurs exist before man?

Evolutionists have long conjectured that dinosaurs were part of a theoretical Great Age of the Reptiles about 200 million years ago. According to their theory, dinosaurs became extinct about 70 million years ago. And man did not evolve until about 4 million years ago. If this is true, no man could ever have seen a live dinosaur.

Why can’t we find dinosaurs in the fossil record?
