I just remembered this one idea I had for a cartoon series.
It took the Good Dinosaur question of "what if dinosaurs didn't go extinct and evolved further", but instead of being about the early, early farmer era with funny human dogs, it jumped to the Roman times.
The main character was this teenage Troodon (before crazy stuff happened to that genus), and he wanted to become a guard for the emperor of his kingdom, who was this big doofy Anklyosaurus. The emperor had adopted this Carnotaurus chick who was a total valley girl (in Roman times. Yeah that makes sense lol) and she was the Troodon's best friend, and love interest.
In the pilot they'd run across this coliseum inhabited entirely by dinosaur girls who appear to be mean vacuous high school girl stereotypes, but they actually turn out to be quite personable. There was a sassy Pachycephalosaurus with a snarky attitude, a sweet Spinosaurus who cried at the drop of a hat, a cool Tyrannosaurus who never talked and was as big and awesome as T-rexes come, and, my favorite, a Baryonyx who wanted to become a mime. Legit, she had the face paint and everything, didn't speak and did all sorts of silly miming maneuvers to communicate. (Again, in Roman times...)
Anachronisms? Sure, but younger me liked the idea lol
