Deinonychus - the "velociraptor" (a fake name made up for jurassic park)
Definately a real name and a real dinosaur. Also definately not the dinosaur in Jurassic Park
The name got used because it "sounds cool"... To be fair, they're right, it does
With regards to book hills, I'd agree with the previous suggestion and use towels, you can shape them and wouldn't need the card triangles. Which I assume would be triangular tubes like a Toblerone box? If you make them, I'd write the name of the book that each one fits to, that way they can line up properly each time without annoying you.
