My favorite pterosaur, dimorphodon. When I was younger, I called them "T. Rex Heads." They were so weird and creepy-looking and I loved them. In one of my comics, I used some speculation when creating the dimorphodons: I had them act like aggressive sea birds, with manes of fur that they would raise when they felt threatened. They would aggressively protect their nests and were very territorial. Imagine prehistoric seagulls. Opportunistic feeders. Of course this is all speculation and I wouldn't be surprised if I was way off the mark. I had a lot of fun creating this little thing. Click for a sound, space to see a drawing I made of it
