1. I am the lead designer and I make the decisions on designing. If you are a skilled drawer want to be an assistant designer, send me a private message and I'll consider it.
2. You can't use designs for a single species that differ from the already established designs.
3. We exclusively use skeletal drawings in designing of dinosaurs, to make them look as accurate as possible(unless the dinosaur doesn't have an appropriate drawing)
4. No giant Tyrannosaurs with feathers: This hasn't been confirmed yet. Only exceptions: Gorgosaurus and Yuturannus.
5. No feathered herbivores!
6. It's recommended to have a design for both genders of a dinosaur species.
