Yep, Dinosaur rhymes 464 and so is the theme of the competition.  Your comic doesn't necessarily have to have a dinosaur in it, though obviously it can, but should in some way be dino related, be it a reference, a pun of some sorts, you know the drill.

I'll close this once all ideas have become extinct and its time to evolve into the next competition.

 

Have at it.
