What if the asteroid dropping on earth was the last act in a war between the dinosaurs and some other alien race?
That's not an underbite, he's eating his own beak. He also asks questions that were just answered.
- How would him eating his beak be related to down syndrome? Also, his asking a question that was just answered, he could just be asking to make sure his thinking is correct or that he heard correctly.
- You're expecting logic on a wild mass guess? Okay, I'll give you a little: one physical sign of Downs is a flatter face. How do you do that with a long beaked/muzzled species?
- Then so does Grandpa Pterodon has it too since the grandparents comment that Don has his grandpa's beak. Though Grandpa doesn't demonstrate many other signs of Downs.
- How on Earth can something eat its own beak? It's a beak!
- You're expecting logic on a wild mass guess? Okay, I'll give you a little: one physical sign of Downs is a flatter face. How do you do that with a long beaked/muzzled species?
- Don's behavior is closer to that of autism. In fact …
- She doesn't exhibit any signs of OCD. She just seems to be a bit of a perfectionist.
- To take this one step further (don’t take this seriously at all, this is just me going insane), what if he’s the Doctor and Thurston is the Master? They mention going to school together, they’re friendly enemies, Thurston has the suave attitude of the Classic Masters and at one point they look like they’re about to re-enact Survival!
Dinosaurs can travel through time whenever they get the urge, with nothing more than an easily obtained ticket. This is, of course, impossible. They can travel to pretty much any place on land and even under the sea using nothing more than a train. This is, of course, impossible. Not only that, but they can zip to those places in the space of minutes and be back home in time for supper. This is, of course, impossible. They can do all this apparently without any worries about being trapped in another time period or causing paradoxes. This is, of course, impossible. They can travel as much as they want and be sure of never meeting themselves because of the embarrassment this usually causes. This, even if the rest were true, is patently impossible. They can gather together dinosaurs of any species from any age together on a moment's notice without any adverse affects on the timeline. This is not merely impossible, but clearly insane, so after they've finished all of this, it only makes sense that they would round it off with a bite to eat at Milliway's, The Restaurant at the End of the Universe.
- The episode "Back In Time" seems to support the idea that the time tunnels were not of dinosaur origin, with the revelation that some of them are, in fact, abandoned and unexplored.
- Jossed: Mrs Pteranodon mentions to Doris Tyrannosaurus in “I’m a Tyrannosaurus” that they adopted Buddy and just didn’t know which species he’d hatch into
- If he knows anything about the asteroid, he's a very good actor because in "Zeppelin: Crater," he and the other characters discuss the idea of an asteroid hitting Earth and he says that his mother told him that it's very rare and not something to worry about.
Additionally, the Fraggles appear to be some kind of small feathered theropod...
This guess is based on Isaac Asimov's The End of Eternity and the Star Trek episode All Our Yesterdays. The dinosaurs, having elected to develop time travel technology over space technology, have created a 200 million year eco technic utopian society that ends at the KT boundary. Dinosaurs living close to the boundary simply move backward when the end date approaches. It may be that the dead are buried near the boundary. This is no longer our world. If humans evolve post asteroid, the fossil record they see will be radically different from what we see. Perhaps one day those ape descended critters will find time travel technology and stop by for a visit.
Dinosaur Train Industries is often coming out with new innovations such as a Dinosaur Train submarine, Dinosaur Train zeppelin, or a train that bores into the Earth's crust. They seem to have unlimited funding, and you can bet they're getting it from time travel to some rich source we're never going to be allowed to see.
Mrs. Pteranodon is abusive to her family and is racist towards Buddy when not on camera. She's discrete about it as to not get alienated by the rest of the dinosaurs and get banned from the Dinosaur Train. This is probably why they're going through to meet all the species: She's trying to find Buddy's family so that they can put him 'where he belongs' and 'live in peace'. However, the rest of the family know better, and probably won't let her give up Buddy. Mr. Pteranodon stays with her because he's worried Mrs will kill him if he leaves, and the kids because the Cretaceous doesn't have CPS.
Think about it. They basically have the same design except Buddy's an anthro dinosaur. Same eye shape, proportions, and general art style. Their designs are even both orange with blue highlights. They're both focused on hypotheses, research, and general science, and given Sid's age, him being interested in dinosaurs would be completely in character. The whole of Dinosaur Train is Sid and possibly his friends getting really invested in a combination roleplay/unit study on dinosaurs. Inaccuracies, and the time-traveling train, are due to the dinosaurs all being kids', albeit science-minded kids', perceptions, and them needing an excuse to explore creatures from different time periods. Dr. Scott the Paleontologist is a teacher trying to get the kids back on track and focused on real dinosaurs as opposed to fictional ones.
- This opens up its own brand of Fridge Horror. As Cenozoic mammals ourselves, are we being farmed as a food source by hyper-intelligent time-traveling dinosaurs while being purposely kept in the dark about it? Is our entire civilization engineered for the primary purpose of feeding theirs? Dear god...
- In the episode Father's Day, it is revealed that Mr. Conductor's father used his drill train to go to the Cenozoic but his train broke down and the tunnel collapsed, trapping him until the episode, in which Mr. Conductor uses a new drill train to go to the Cenozoic (who only knew the name of the era because the train Systems said so), and they get his father back to the Mesozoic.
