How To unlock the other Dinosaurs?

Hello guys! So as you know the JW website just launched and one of the things you could view are the dinosaurs. Now it gives you a list of dinosaurs to click on like the touch screen monitor that we have also seen. Before we get into this I have a theory that the dinosaurs that we see that are on the touch screen only a very select few will make it in JW, most likely the ones we can view on the website. Now with that being said the screen only has three unlocked dinosaurs (T-Rex, Apatosaurus, and Triceratops.) how do you think we will unlock the other ones? Maybe someone will leak these on twitter or instagram or something. What do you think?
