Triceratops
Originally Designed: 2004
Revised: 2012, 2015
2012 version Diagrammed in:
Another very old design of mine. I still remember the original version which was very boxy (not pictured) and was then refined somewhat with two narrow sinks along the back. The actual crease pattern was identical to the diagrammed version outside of that minor change.
While preparing for the Origami Tanteidan Convention in 2015, I folded the model again with some upgrades which mainly added the missing lower jaw and refined the proportions.
the 2012 and 2015 crease patterns.
