You don’t need a very big sheet of paper for this model, even though there are quite a bit of fine complex fold for the feet and the head. I have used a 20cm square paper and it yield a 17cm (head to tail) model nicely.
As the model is small, it is best to use a slightly stiffer paper for folding. Thicker paper may still be possible as there are few stack up layers nor tricky sink maneuver. I have used the Kraft paper for folding this model and the result turned out to be very satisfactory
The highlight of this model is on the ‘sail’ at the back of the model and the feet. This ‘sail’ is a signature design of Yoshino’s model. you can find it again in his Horse model.
The feet design has 3 toes, folded only with a smaller little portion of triangular shape paper, yet nicely formed to proportion.
Yoshino cleverly uses the tail to support the model and has enabled this small dinosaur to stand on its own.
