Thalassodromeus sethi, a particularly handsome pterosaur from the Early Cretaceous of what is now Brazil. It had a wingspan of about 4,5 metres, which isn't particularly big on pterosaur standards, but compared to modern birds, it's still huge.
Not much more to add. I'm definitely not acting like an adult tonight. It's midnight, I just ate so many cookies my stomach hurts, and instead of sleeping, I'm painting pterosaurs. Just because I can.
