If Cenozoic animals only have a cameos or secondary roles (like the Mosasaurus) in a JP film then it's not a spinoff.

If Cenozoic animals have main focus in a film releated to the JP film series then it's a spinoff.

What is the JP franchise mostly about? Dinosaurs. Sure flying reptiles and aquatic reptiles appear but in secondary roles.

Take away dinosaurs out of the main picture (even if a Cenozoic Park film has dinosaurs but just minor screentime) then it's a spinoff plain and simple.
