Dino Dex.

Dex is a 9-year-old artist, explorer, and "paleontologist in training". Like Dan, Trek, and his big sister Dana, Dex uses his Dino Field Guide to magically see and study dinosaurs in the real world. Thanks to his artistic eye, Dex envisions them a bit differently, getting right into the action to reconsider how prehistoric creatures like the T. rex, Velociraptor, and Megalodon looked and lived.
