You can't unfortunately. A dinosaur that has a gold ranking is one you can get far into the game. My favourite is Albertosaurus (6000 health, up to 2000 damage).

This is JPB right?
Life cannot be contained, it breaks walls, crashes through barriers sometimes painfully, but uh... Life uh, finds a way

Yes it is (I think at least, that's what I got out of this).

I just started playing last week and only level 11, so maybe im wrong, but if you referring to gold dinos in the arena the only ones I have that are gold are my premium purchased ones.

You're not wrong. Most of my dinosaurs are level 40, and my gold ones are the very expensive, later in the game dinosaurs. If it's bronze as a level 1, it's a bronze all the way through.
