Dex is a 9-year-old artist, explorer, and "paleontologist in training". Like Dan, Trek, and 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, reconsidering how prehistoric creatures looked and lived. Join Dex and his neighbor, Kayla, as they question what we thought we knew about dinosaurs.
