Here's my suggestions

Cretaceous morroco ( ornithocheirus , spinosaurus , iguanadon , poloracamus , carachadontosaurus , liopuerdion and opthamolosaurus )

Miocene south America ( silmodon populator , titanis , barinasuchus, demosdus draculae and giant ground sloth )

These are my two suggestions

If this counts, I'm saying:

Takes place in this little continent with no humans where dinosaurs co-exist with other animals. And the animals have human-like brains that they can build houses and castles.

It's pretty much like ICE AGE: Dawn of the dinosaurs.

The main characters are Sobbie Pobbie, Monsty Permian, Singey Dragon, Blitzercup, and CherryCat. Along with many background dinosaurs and some other prehistoric fauna.
