Survival is a big theme. In these fanfictions, humans have to figure out how to survive in a world dominated by dinosaurs. They need to find food, shelter, and avoid being eaten. The theme of friendship also appears. Sometimes a human befriends a dinosaur, like in the story where a lonely boy forms a bond with a gentle herbivore dinosaur. Additionally, the idea of time - travel is common. It allows for the mixing of different eras, with humans from the present going back to the dinosaur age or vice versa.
One common theme is the idea of different dinosaur species interacting romantically. For example, a T - Rex and a Triceratops might be characters in a love story.

And of course, there are the classic themes of love and conflict, like a human falling in love with a dinosaur - like being or having a conflict with a group of dinosaurs over territory or resources.

The exploration of an ancient and dangerous world is also a theme. Dinosaur war novels often take readers to a prehistoric or dinosaur - inhabited world full of unknowns. The characters need to explore this world while also dealing with the threat of dinosaurs, like in 'The Lost World' where the exploration of the lost land with dinosaurs is filled with perils and battles.
A common theme is friendship. Just like in the main MLP series, in these fanfics, the ponies often form friendships with dinosaurs or help each other out. For example, they might team up to solve a problem that threatens both their worlds.
