This Is Why Dinosaurs Looked Nothing Like in Movies

Meet a distant relative of a velociraptor. Look at these big fangs: they could easily pierce the scaly armor of any other dinosaur. This dinosaur’s peculiar backbone let it move on four legs pretty fast... Wait a second. I guess I mixed it up; this is a skeleton of a regular mouse.
But hold on, don’t turn it off. Because the velociraptor I just showed you, has nothing to do with dinosaurs either. It’s a figment of Steven Spielberg’s imagination translated into reality by the Jurassic Park movie crew. So how did dinosaurs really look like?
Why were the first finds buried back? Why would scientists break dinosaurs' bones?
And who’s hiding from us the truth about dinosaurs?
