My yardstick for detecting bullshit is to look how many (((movies))) were made about the subject. Right now there are 1187 films about dinosaurs. If you pay attention to Jurassic Park, they actually use frog DNA to grow the "dinosaurs", a bit of soft disclosure of the hoax by Spielberg. But of course they really do feel the need to in some way tell us the truth, both to mock us and forgive their karmic debt for lying.
