So this is going to be an arcade-y flight sim in a similar vein to Star Fox or X-Wing: Rogue Squadron.The backstory here is that sentient dinosaurs have developed a technological civilization just in time to address the "asteroid problem" which caused the K-Pg extinction event. Your particular faction of sentient dinosaurs (have yet to decide on a name for their race) is building a rocket-ship to redirect/destroy the asteroid before it hits Earth, but a rival faction has stolen the parts of it and scattered them on various tropical islands. You have to take some commandos to the islands aboard your steampunk robot pterosaur (yeah....) and drop them off so that the parts can be retrieved and the rocket built. Along the way, you'll have to defend yourself against enemy fighters, of course, which is what the gameplay will mostly be about.
I guess I'm reinterpreting the theme to be, "What if the dinosaurs never went extinct because they had a space program?"
