Evolution of the Dinosaur

Tyrannosaurus-rex.73505

Dinosaurs are believed to have gone extinct 65.4 million years ago. But did they? New scientific theories suggest that several dinosaurs are still roaming the earth. Others say this is nonsense. But, other theories say that dinosaurs are still around, but not as you would think. Some say that dinosaurs have evolved into present day animals, like Velociraptor and the Bald Eagle share similarities to points beyond imagination. But, science continues to throw curveballs at us, and your descision is influenced only by what you believe.

Dinosauromorphs, Dinosaurifromes and Nyasasaurus evolved into Dinosaurs.
