Montroll's Brontosaurus

Montroll's Brontosaurus is a single-sheet origami dinosaur model created by American origami designer John Montroll. It is noted for its clean, elegant design that captures the long neck and tail of the prehistoric creature.

The model is generally aimed at intermediate to advanced folders, as it requires precise sinking and shaping to form the dinosaur's distinct features. Folders need to be comfortable with complex crease patterns to achieve Montroll's signature aesthetic.

Because of its long neck and tail, a paper that holds creases well, such as standard kami or a slightly heavier duo paper, is recommended. Using paper that is too thin might cause the neck to droop, while paper that is too thick will make the folds bulky.

You can find the step-by-step instructions for this famous origami model in John Montroll's various animal origami book series. It is frequently included in his collections focusing on prehistoric or extinct creatures.
