Here is a papercraft I created of my nasty, battle-scarred, one-eyed Hyaenodon character. This requires photoshop and rar-opening software to make. Also, this is quite difficult, probably being a 9/10. The reason why is this model was never really meant to be a papercraft, and she is intended to be small to be in scale with the other prehistoric critters. You can make this easier by making her an H. Gigas instead of an H. Horridus (increasing the papercraft size).
