Every dinosaur playing card is related to an official Clade-Gravim Trading Card. It will have the C-G nickname and Trading Card number at the top of the card. An official "Luterio" rendition of the Dino will be in the center. At the bottom of the playing card will be the scientific name for the dinosaur. As with all Clade-Gravim dinosaur products we hope you learn while playing. Play like the classic games "Old Maid" and "Go Fish". Additional game suggestions included.
