Brontosaurus (Pureland)

This Brontosaurus is formed from only simple valley and mountain folds, following the Pureland origami definition championed by the late John Smith. There are some unusual reference points, elevating this folding sequence to a "low intermediate" level designation. Diagrams for this can be found in the book Prehistoric Origami:

A single square of larger kami is recommended (10"/25cm). With more practice you can use smaller sheets.
