Dinosaur Train/Fridge

Fridge Logic

 * Okay so... Time Travel is a reality in the dinosaur society. It's so commonly used that the various dinosaurs react to time travelers in pretty much the same way as they would with tourists. Than again, it's basically the writer's way to avoid Temporally Misplaced Wildlife, which is fine.
 * Plot Bunny: Suppose a few dinosaurs miss the train, and the local train station only gets a train at very rare random intervals. They decide to start a new family in their new time and end up creating a new occurrence of their species either before their actual appearance, or after their extinction. Time paradox at its purest.
 * Remember, the show is for children who are just learning to identify different animals by name. But the producers did kind of acknowledge this idea. There is an episode where Tiny accidentally leaves her favorite toy in a friend's nest before boarding the train (it is rescued by another pterosaur) and that's more than enough drama for the target audience.

Fridge Horror

 * Hell if we're going this far. "Hey, Mr. Conductor, how come you've never taken us past the late Cretaceous?"
 * In one episode, the characters are comparing their collections and one of them had a collection of fossils. In other words, they had a collection of the fossilized remains of dinosaurs they met earlier.
