Dinosaur serrations

[Jonathan Lighter]

Cartoon dinosaurs (other than Stegosaurus) often used to be drawn with a
line of rather small, skinny serrations along their spines.  Why was that?
More to the point, does herpetology provide a more technical terms than
"serrations"?  Assuming that comparable structures exist on some reptiles
somewhere.
