Material: colored paper.

1. Prepare a square colored paper. Fold in half once along the diagonal of the square, and fold both sides inward with the diagonal as a reference.

2. After folding inward, the remaining small triangle is folded backwards. Open it all again and fold it inward, overlapping with the corner point in the lower left corner of the vertex triangle.

3. Fold the adjacent edge on the left, and also overlap the point on the lower right corner of the triangle in the upper right corner. Fold it up and open it all.

4. Press the creases and corners of the just folded two steps into such a small square. Conversely, fold both sides of the small square inward with the diagonal as the center. Then open all the newly folded ones in turn.

5. Fold inward according to the crease just folded. Then fold the corner at the other end inward and press the excess part in.

6. The small square is folded inward with the diagonal as the center. Press the folded crease into this shape. The other end is also folded inward around the diagonal. After folding, press the crease inward, and treat each side in the same way.

7. Fold the middle corner up and then down, flush with the corner of the small triangle. Like little wings, pull the horn to the top of Tyrannosaurus Rex's head, and then fold the extra part inward.

8. After folding the previous step, fold it in half. Fold the triangle near the head outward, which looks like little wings, but it is actually the forelimb of Tyrannosaurus Rex. Then fold the hind legs of Tyrannosaurus rex in the direction of its forelimbs.
