Dinosaur 101

Let's be Dinosaur Mythbusters!

Myth #1
Dinosaurs lived alongside cavemen.
Although the image of human cave dwellers hunting dinosaurs is well established in fiction  it is far from accurate. People didn't evolve until about 65 million years after the dinosaurs' extinction. Except for the birds, who are the sole surviving descendants of the dinosaurs, dinosaurs and people are well separated.

Myth #2
All dinosaurs were huge creatures.
There were plenty of small and medium-sized dinosaurs. The smallest dinosaur yet discovered was the size of a chicken!  

Myth #3
Dinosaurs could fly and swim.
All dinosaurs lived on the land; none of them lived in the seas or flew (until the birds)! Neither the flying Pterosaurs, nor the swimming Ichthyrosaurs were dinosaurs, although all were closely related.
Some advanced meat-eating dinosaurs did develop feathers, and evolved into birds.
