I always have way more fun drawing pterosaurs doing non-flying-related things. Although they’ve traditionally been depicted as sprawling and ungainly on the ground, the anatomy of many pterosaurs actually suggests they stood semi-erect (or fully erect in some types) and were competent at walking and even running.

So this is a male Pteranodon sternbergi (sometimes assigned to its own genus and called Geosternbergia sternbergi instead). Pteranodon is probably the most well-known pterosaur — over 1000 specimens have been found — and most of the time when a movie or TV show depicts a pterosaur it’s either a Pteranodon or a weird chimeric mash-up between it and Rhamphorhynchus.

Pteranodon specimens show marked sexual dimorphism, with the large-crested males being about one-and-a-half times bigger than the small-crested females.
