I am an Iranian folder from Shiraz, and this is a new model of mine starting from a triangular sheet. Perhaps you have seen my Right-triangle-bird published here. Around the same time, I designed three similar models with right triangle paper: a bird, dragon and dinosaur. This is the dinosaur model, a deinonychus. Deinonychus was a small and carnivorous dinosaur and was very fast and smart. It was lived during the early cretaceous period.
