You can check eBay. I've seen a CD with dinosaur 3D models in there. Search for "3D Models" and it should bring them up. I don't know if they work in Poser, but you can check them out. Also, there used to be a posable pteranodon in one of these forums at one time, but it disappeared and I don't know where it went. There was also a website with excellent posable dinosaurs of various types and it might have included a pteranodon, but I've lost the link to it. If anyone can remember what that was, please let all of us know. Melanie
