I wasn't happy with the proportions of the previous Acteosaur, so I ended up measuring the best fossil image I could find of it and re-drawing it to be more accurate. The head is still very speculative, since said fossil is headless, but several close relatives have intact heads, so I did the best I could. The paddle tail is also speculative. It was aquatic, so it's very possible, but not all aquatic reptiles develop paddles.
