Pteranodons were large flying reptiles who claimed to be more famous than Pterodactyls. Their wingspan could reach 20 feet, or 6 meters. Humans have found over 1,000 fossil specimens.
Further down the wormhole, shout-out to the ancient Mothership: Pteranodons lived in the area of the Western Interior Seaway, which for a time, split the present North American continent in two.
