Dinosaurs Make Everything Better

The PCs are all dinosaurs. You run around avoiding meteors and stomping things.

This could be played totally straight where the players are all dinosaurs doing dinosaur things. I spent a lot of time pretending I was a dinosaur as a kid, so there's got to be some fun there.

Or it could be more of a reverse Turok kind of deal, and the dinosaur-PCs eat Marines or Lost World explorers or scientists or whoever it would be entertaining for dinosaurs to eat.
